-module ActionView
-  # There's also a convenience method for rendering sub templates within the current controller that depends on a
-  # single object (we call this kind of sub templates for partials). It relies on the fact that partials should
-  # follow the naming convention of being prefixed with an underscore -- as to separate them from regular
-  # templates that could be rendered on their own.
-  #
-  # In a template for Advertiser#account:
-  #
-  #  <%= render :partial => "account" %>
-  #
-  # This would render "advertiser/_account.erb" and pass the instance variable @account in as a local variable
-  # +account+ to the template for display.
-  #
-  # In another template for Advertiser#buy, we could have:
-  #
-  #   <%= render :partial => "account", :locals => { :account => @buyer } %>
-  #
-  #   <% for ad in @advertisements %>
-  #     <%= render :partial => "ad", :locals => { :ad => ad } %>
-  #   <% end %>
-  #
-  # This would first render "advertiser/_account.erb" with @buyer passed in as the local variable +account+, then
-  # render "advertiser/_ad.erb" and pass the local variable +ad+ to the template for display.
-  #
-  # == Rendering a collection of partials
-  #
-  # The example of partial use describes a familiar pattern where a template needs to iterate over an array and
-  # render a sub template for each of the elements. This pattern has been implemented as a single method that
-  # accepts an array and renders a partial by the same name as the elements contained within. So the three-lined
-  # example in "Using partials" can be rewritten with a single line:
-  #
-  #   <%= render :partial => "ad", :collection => @advertisements %>
-  #
-  # This will render "advertiser/_ad.erb" and pass the local variable +ad+ to the template for display. An
-  # iteration counter will automatically be made available to the template with a name of the form
-  # +partial_name_counter+. In the case of the example above, the template would be fed +ad_counter+.
-  #
-  # NOTE: Due to backwards compatibility concerns, the collection can't be one of hashes. Normally you'd also
-  # just keep domain objects, like Active Records, in there.
-  #
-  # == Rendering shared partials
-  #
-  # Two controllers can share a set of partials and render them like this:
-  #
-  #   <%= render :partial => "advertisement/ad", :locals => { :ad => @advertisement } %>
-  #
-  # This will render the partial "advertisement/_ad.erb" regardless of which controller this is being called from.
-  #
-  # == Rendering objects with the RecordIdentifier
-  #
-  # Instead of explicitly naming the location of a partial, you can also let the RecordIdentifier do the work if
-  # you're following its conventions for RecordIdentifier#partial_path. Examples:
-  #
-  #  # @account is an Account instance, so it uses the RecordIdentifier to replace
-  #  # <%= render :partial => "accounts/account", :locals => { :account => @buyer } %>
-  #  <%= render :partial => @account %>
-  #
-  #  # @posts is an array of Post instances, so it uses the RecordIdentifier to replace
-  #  # <%= render :partial => "posts/post", :collection => @posts %>
-  #  <%= render :partial => @posts %>
-  #
-  # == Rendering the default case
-  #
-  # If you're not going to be using any of the options like collections or layouts, you can also use the short-hand
-  # defaults of render to render partials. Examples:
-  #
-  #  # Instead of <%= render :partial => "account" %>
-  #  <%= render "account" %>
-  #
-  #  # Instead of <%= render :partial => "account", :locals => { :account => @buyer } %>
-  #  <%= render "account", :account => @buyer %>
-  #
-  #  # @account is an Account instance, so it uses the RecordIdentifier to replace
-  #  # <%= render :partial => "accounts/account", :locals => { :account => @account } %>
-  #  <%= render(@account) %>
-  #
-  #  # @posts is an array of Post instances, so it uses the RecordIdentifier to replace
-  #  # <%= render :partial => "posts/post", :collection => @posts %>
-  #  <%= render(@posts) %>
-  #
-  # == Rendering partials with layouts
-  #
-  # Partials can have their own layouts applied to them. These layouts are different than the ones that are
-  # specified globally for the entire action, but they work in a similar fashion. Imagine a list with two types
-  # of users:
-  #
-  #   <%# app/views/users/index.html.erb &>
-  #   Here's the administrator:
-  #   <%= render :partial => "user", :layout => "administrator", :locals => { :user => administrator } %>
-  #
-  #   Here's the editor:
-  #   <%= render :partial => "user", :layout => "editor", :locals => { :user => editor } %>
-  #
-  #   <%# app/views/users/_user.html.erb &>
-  #   Name: <%= user.name %>
-  #
-  #   <%# app/views/users/_administrator.html.erb &>
-  #   <div id="administrator">
-  #     Budget: $<%= user.budget %>
-  #     <%= yield %>
-  #   </div>
-  #
-  #   <%# app/views/users/_editor.html.erb &>
-  #   <div id="editor">
-  #     Deadline: <%= user.deadline %>
-  #     <%= yield %>
-  #   </div>
-  #
-  # ...this will return:
-  #
-  #   Here's the administrator:
-  #   <div id="administrator">
-  #     Budget: $<%= user.budget %>
-  #     Name: <%= user.name %>
-  #   </div>
-  #
-  #   Here's the editor:
-  #   <div id="editor">
-  #     Deadline: <%= user.deadline %>
-  #     Name: <%= user.name %>
-  #   </div>
-  #
-  # You can also apply a layout to a block within any template:
-  #
-  #   <%# app/views/users/_chief.html.erb &>
-  #   <% render(:layout => "administrator", :locals => { :user => chief }) do %>
-  #     Title: <%= chief.title %>
-  #   <% end %>
-  #
-  # ...this will return:
-  #
-  #   <div id="administrator">
-  #     Budget: $<%= user.budget %>
-  #     Title: <%= chief.name %>
-  #   </div>
-  #
-  # As you can see, the <tt>:locals</tt> hash is shared between both the partial and its layout.
-  #
-  # If you pass arguments to "yield" then this will be passed to the block. One way to use this is to pass
-  # an array to layout and treat it as an enumerable.
-  #
-  #   <%# app/views/users/_user.html.erb &>
-  #   <div class="user">
-  #     Budget: $<%= user.budget %>
-  #     <%= yield user %>
-  #   </div>
-  #
-  #   <%# app/views/users/index.html.erb &>
-  #   <% render :layout => @users do |user| %>
-  #     Title: <%= user.title %>
-  #   <% end %>
-  #
-  # This will render the layout for each user and yield to the block, passing the user, each time.
-  #
-  # You can also yield multiple times in one layout and use block arguments to differentiate the sections.
-  #
-  #   <%# app/views/users/_user.html.erb &>
-  #   <div class="user">
-  #     <%= yield user, :header %>
-  #     Budget: $<%= user.budget %>
-  #     <%= yield user, :footer %>
-  #   </div>
-  #
-  #   <%# app/views/users/index.html.erb &>
-  #   <% render :layout => @users do |user, section| %>
-  #     <%- case section when :header -%>
-  #       Title: <%= user.title %>

+  #   <%= render :partial => "account", :locals => { :account => @buyer } %>
+  #
+  #   <% for ad in @advertisements %>
+  #     <%= render :partial => "ad", :locals => { :ad => ad } %>
+  #   <% end %>
+  #
+  # This would first render "advertiser/_account.erb" with @buyer passed in as the local variable +account+, then
+  # render "advertiser/_ad.erb" and pass the local variable +ad+ to the template for display.
+  #
+  # == Rendering a collection of partials
+  #
+  # The example of partial use describes a familiar pattern where a template needs to iterate over an array and
+  # render a sub template for each of the elements. This pattern has been implemented as a single method that
+  # accepts an array and renders a partial by the same name as the elements contained within. So the three-lined
+  # example in "Using partials" can be rewritten with a single line:
+  #
+  #   <%= render :partial => "ad", :collection => @advertisements %>
+  #
+  # This will render "advertiser/_ad.erb" and pass the local variable +ad+ to the template for display. An
+  # iteration counter will automatically be made available to the template with a name of the form
+  # +partial_name_counter+. In the case of the example above, the template would be fed +ad_counter+.
+  #
+  # NOTE: Due to backwards compatibility concerns, the collection can't be one of hashes. Normally you'd also
+  # just keep domain objects, like Active Records, in there.
+  #
+  # == Rendering shared partials
+  #
+  # Two controllers can share a set of partials and render them like this:
+  #
+  #   <%= render :partial => "advertisement/ad", :locals => { :ad => @advertisement } %>
+  #
+  # This will render the partial "advertisement/_ad.erb" regardless of which controller this is being called from.
+  #
+  # == Rendering objects with the RecordIdentifier
+  #
+  # Instead of explicitly naming the location of a partial, you can also let the RecordIdentifier do the work if
+  # you're following its conventions for RecordIdentifier#partial_path. Examples:
+  #
+  #  # @account is an Account instance, so it uses the RecordIdentifier to replace
+  #  # <%= render :partial => "accounts/account", :locals => { :account => @buyer } %>
+  #  <%= render :partial => @account %>
+  #
+  #  # @posts is an array of Post instances, so it uses the RecordIdentifier to replace
+  #  # <%= render :partial => "posts/post", :collection => @posts %>
+  #  <%= render :partial => @posts %>
+  #
+  # == Rendering the default case
+  #
+  # If you're not going to be using any of the options like collections or layouts, you can also use the short-hand
+  # defaults of render to render partials. Examples:
+  #
+  #  # Instead of <%= render :partial => "account" %>
+  #  <%= render "account" %>
+  #
+  #  # Instead of <%= render :partial => "account", :locals => { :account => @buyer } %>
+  #  <%= render "account", :account => @buyer %>
+  #
+  #  # @account is an Account instance, so it uses the RecordIdentifier to replace
+  #  # <%= render :partial => "accounts/account", :locals => { :account => @account } %>
+  #  <%= render(@account) %>
+  #
+  #  # @posts is an array of Post instances, so it uses the RecordIdentifier to replace
+  #  # <%= render :partial => "posts/post", :collection => @posts %>
+  #  <%= render(@posts) %>
+  #
+  # == Rendering partials with layouts
+  #
+  # Partials can have their own layouts applied to them. These layouts are different than the ones that are
+  # specified globally for the entire action, but they work in a similar fashion. Imagine a list with two types
+  # of users:
+  #
+  #   <%# app/views/users/index.html.erb &>
+  #   Here's the administrator:
+  #   <%= render :partial => "user", :layout => "administrator", :locals => { :user => administrator } %>
+  #
+  #   Here's the editor:
+  #   <%= render :partial => "user", :layout => "editor", :locals => { :user => editor } %>
+  #
+  #   <%# app/views/users/_user.html.erb &>
+  #   Name: <%= user.name %>
+  #
+  #   <%# app/views/users/_administrator.html.erb &>
+  #   <div id="administrator">
+  #     Budget: $<%= user.budget %>
+  #     <%= yield %>
+  #   </div>
+  #
+  #   <%# app/views/users/_editor.html.erb &>
+  #   <div id="editor">
+  #     Deadline: <%= user.deadline %>
+  #     <%= yield %>
+  #   </div>
+  #
+  # ...this will return:
+  #
+  #   Here's the administrator:
+  #   <div id="administrator">
+  #     Budget: $<%= user.budget %>
+  #     Name: <%= user.name %>
+  #   </div>
+  #
+  #   Here's the editor:
+  #   <div id="editor">
+  #     Deadline: <%= user.deadline %>
+  #     Name: <%= user.name %>
+  #   </div>
+  #
+  # You can also apply a layout to a block within any template:
+  #
+  #   <%# app/views/users/_chief.html.erb &>
+  #   <% render(:layout => "administrator", :locals => { :user => chief }) do %>
+  #     Title: <%= chief.title %>
+  #   <% end %>
+  #
+  # ...this will return:
+  #
+  #   <div id="administrator">
+  #     Budget: $<%= user.budget %>
+  #     Title: <%= chief.name %>
+  #   </div>
+  #
+  # As you can see, the <tt>:locals</tt> hash is shared between both the partial and its layout.
+  #
+  # If you pass arguments to "yield" then this will be passed to the block. One way to use this is to pass
+  # an array to layout and treat it as an enumerable.
+  #
+  #   <%# app/views/users/_user.html.erb &>
+  #   <div class="user">
+  #     Budget: $<%= user.budget %>
+  #     <%= yield user %>
+  #   </div>
+  #
+  #   <%# app/views/users/index.html.erb &>
+  #   <% render :layout => @users do |user| %>
+  #     Title: <%= user.title %>
+  #   <% end %>
+  #
+  # This will render the layout for each user and yield to the block, passing the user, each time.
+  #
+  # You can also yield multiple times in one layout and use block arguments to differentiate the sections.
+  #
+  #   <%# app/views/users/_user.html.erb &>
+  #   <div class="user">
+  #     <%= yield user, :header %>
+  #     Budget: $<%= user.budget %>
+  #     <%= yield user, :footer %>
+  #   </div>
+  #
+  #   <%# app/views/users/index.html.erb &>
+  #   <% render :layout => @users do |user, section| %>
+  #     <%- case section when :header -%>
+  #       Title: <%= user.title %>
+  #     <%- when :footer -%>
+  #       Deadline: <%= user.deadline %>
+  #     <%- end -%>

-      #
-      # Pass a hash in the second argument (+path+) to specify the request method.  This is useful for routes

-    # Adds the +assert_select+ method for use in Rails functional
-    # test cases, which can be used to make assertions on the response HTML of a controller
-    # action. You can also call +assert_select+ within another +assert_select+ to
-    # make assertions on elements selected by the enclosing assertion.
-    #
-    # Use +css_select+ to select elements without making an assertions, either
-    # from the response HTML or elements selected by the enclosing assertion.
-    # 
-    # In addition to HTML responses, you can make the following assertions:
-    # * +assert_select_rjs+ - Assertions on HTML content of RJS update and insertion operations.
-    # * +assert_select_encoded+ - Assertions on HTML encoded inside XML, for example for dealing with feed item descriptions.
-    # * +assert_select_email+ - Assertions on the HTML body of an e-mail.
-    #
-    # Also see HTML::Selector to learn how to use selectors.
-    module SelectorAssertions
-      # :call-seq:
-      #   css_select(selector) => array
-      #   css_select(element, selector) => array
-      #
-      # Select and return all matching elements.
-      #
-      # If called with a single argument, uses that argument as a selector
-      # to match all elements of the current page. Returns an empty array
-      # if no match is found.
-      #
-      # If called with two arguments, uses the first argument as the base
-      # element and the second argument as the selector. Attempts to match the
-      # base element and any of its children. Returns an empty array if no
-      # match is found.
-      #
-      # The selector may be a CSS selector expression (String), an expression
-      # with substitution values (Array) or an HTML::Selector object.
-      #
-      # ==== Examples

-      #   assert_select(selector, equality?, message?)
-      #   assert_select(element, selector, equality?, message?)
-      #
-      # An assertion that selects elements and makes one or more equality tests.
-      #
-      # If the first argument is an element, selects all matching elements
-      # starting from (and including) that element and all its children in
-      # depth-first order.
-      #
-      # If no element if specified, calling +assert_select+ selects from the
-      # response HTML unless +assert_select+ is called from within an +assert_select+ block.
-      #
-      # When called with a block +assert_select+ passes an array of selected elements
-      # to the block. Calling +assert_select+ from the block, with no element specified,
-      # runs the assertion on the complete set of elements selected by the enclosing assertion.
-      # Alternatively the array may be iterated through so that +assert_select+ can be called
-      # separately for each element.
-      #
-      #
-      # ==== Example
-      # If the response contains two ordered lists, each with four list elements then:
-      #   assert_select "ol" do |elements|
-      #     elements.each do |element|
-      #       assert_select element, "li", 4
-      #     end
-      #   end
-      #
-      # will pass, as will:
-      #   assert_select "ol" do
-      #     assert_select "li", 8
-      #   end
-      #
-      # The selector may be a CSS selector expression (String), an expression
-      # with substitution values, or an HTML::Selector object.
-      #
-      # === Equality Tests
-      #
-      # The equality test may be one of the following:
-      # * <tt>true</tt> - Assertion is true if at least one element selected.
-      # * <tt>false</tt> - Assertion is true if no element selected.
-      # * <tt>String/Regexp</tt> - Assertion is true if the text value of at least
-      #   one element matches the string or regular expression.
-      # * <tt>Integer</tt> - Assertion is true if exactly that number of
-      #   elements are selected.
-      # * <tt>Range</tt> - Assertion is true if the number of selected
-      #   elements fit the range.
-      # If no equality test specified, the assertion is true if at least one
-      # element selected.
-      #
-      # To perform more than one equality tests, use a hash with the following keys:
-      # * <tt>:text</tt> - Narrow the selection to elements that have this text
-      #   value (string or regexp).
-      # * <tt>:html</tt> - Narrow the selection to elements that have this HTML
-      #   content (string or regexp).
-      # * <tt>:count</tt> - Assertion is true if the number of selected elements
-      #   is equal to this value.
-      # * <tt>:minimum</tt> - Assertion is true if the number of selected
-      #   elements is at least this value.
-      # * <tt>:maximum</tt> - Assertion is true if the number of selected
-      #   elements is at most this value.
-      #
-      # If the method is called with a block, once all equality tests are
-      # evaluated the block is called with an array of all matched elements.
-      #
-      # ==== Examples
-      #
-      #   # At least one form element
-      #   assert_select "form"
-      #
-      #   # Form element includes four input fields
-      #   assert_select "form input", 4

-      # === Narrowing down
-      #
-      # With no arguments, asserts that one or more elements are updated or
-      # inserted by RJS statements.
-      #
-      # Use the +id+ argument to narrow down the assertion to only statements
-      # that update or insert an element with that identifier.
-      #
-      # Use the first argument to narrow down assertions to only statements
-      # of that type. Possible values are <tt>:replace</tt>, <tt>:replace_html</tt>, 
-      # <tt>:show</tt>, <tt>:hide</tt>, <tt>:toggle</tt>, <tt>:remove</tt> and
-      # <tt>:insert_html</tt>.
-      #
-      # Use the argument <tt>:insert</tt> followed by an insertion position to narrow
-      # down the assertion to only statements that insert elements in that
-      # position. Possible values are <tt>:top</tt>, <tt>:bottom</tt>, <tt>:before</tt>
-      # and <tt>:after</tt>.
-      #
-      # Using the <tt>:remove</tt> statement, you will be able to pass a block, but it will
-      # be ignored as there is no HTML passed for this statement.
-      #
-      # === Using blocks
-      #
-      # Without a block, +assert_select_rjs+ merely asserts that the response
-      # contains one or more RJS statements that replace or update content.
-      #
-      # With a block, +assert_select_rjs+ also selects all elements used in
-      # these statements and passes them to the block. Nested assertions are
-      # supported.
-      #
-      # Calling +assert_select_rjs+ with no arguments and using nested asserts
-      # asserts that the HTML content is returned by one or more RJS statements.
-      # Using +assert_select+ directly makes the same assertion on the content,
-      # but without distinguishing whether the content is returned in an HTML
-      # or JavaScript.
-      #
-      # ==== Examples
-      #
-      #   # Replacing the element foo.
-      #   # page.replace 'foo', ...
-      #   assert_select_rjs :replace, "foo"

-  #   class GuestBookController < ActionController::Base
-  #     def index
-  #       @entries = Entry.find(:all)
-  #     end
-  #
-  #     def sign
-  #       Entry.create(params[:entry])
-  #       redirect_to :action => "index"
-  #     end
-  #   end
-  #
-  # Actions, by default, render a template in the <tt>app/views</tt> directory corresponding to the name of the controller and action
-  # after executing code in the action. For example, the +index+ action of the GuestBookController would render the
-  # template <tt>app/views/guestbook/index.erb</tt> by default after populating the <tt>@entries</tt> instance variable.
-  #
-  # Unlike index, the sign action will not render a template. After performing its main purpose (creating a
-  # new entry in the guest book), it initiates a redirect instead. This redirect works by returning an external
-  # "302 Moved" HTTP response that takes the user to the index action.
-  #
-  # The index and sign represent the two basic action archetypes used in Action Controllers. Get-and-show and do-and-redirect.
-  # Most actions are variations of these themes.
-  #
-  # == Requests
-  #
-  # Requests are processed by the Action Controller framework by extracting the value of the "action" key in the request parameters.
-  # This value should hold the name of the action to be performed. Once the action has been identified, the remaining
-  # request parameters, the session (if one is available), and the full request with all the HTTP headers are made available to
-  # the action through instance variables. Then the action is performed.
-  #
-  # The full request object is available with the request accessor and is primarily used to query for HTTP headers. These queries
-  # are made by accessing the environment hash, like this:
-  #
-  #   def server_ip
-  #     location = request.env["SERVER_ADDR"]
-  #     render :text => "This server hosted at #{location}"
-  #   end
-  #
-  # == Parameters
-  #
-  # All request parameters, whether they come from a GET or POST request, or from the URL, are available through the params method
-  # which returns a hash. For example, an action that was performed through <tt>/weblog/list?category=All&limit=5</tt> will include
-  # <tt>{ "category" => "All", "limit" => 5 }</tt> in params.
-  #
-  # It's also possible to construct multi-dimensional parameter hashes by specifying keys using brackets, such as:
-  #
-  #   <input type="text" name="post[name]" value="david">
-  #   <input type="text" name="post[address]" value="hyacintvej">
-  #
-  # A request stemming from a form holding these inputs will include <tt>{ "post" => { "name" => "david", "address" => "hyacintvej" } }</tt>.
-  # If the address input had been named "post[address][street]", the params would have included
-  # <tt>{ "post" => { "address" => { "street" => "hyacintvej" } } }</tt>. There's no limit to the depth of the nesting.
-  #
-  # == Sessions
-  #
-  # Sessions allows you to store objects in between requests. This is useful for objects that are not yet ready to be persisted,
-  # such as a Signup object constructed in a multi-paged process, or objects that don't change much and are needed all the time, such
-  # as a User object for a system that requires login. The session should not be used, however, as a cache for objects where it's likely
-  # they could be changed unknowingly. It's usually too much work to keep it all synchronized -- something databases already excel at.
-  #
-  # You can place objects in the session by using the <tt>session</tt> method, which accesses a hash:
-  #
-  #   session[:person] = Person.authenticate(user_name, password)
-  #
-  # And retrieved again through the same hash:
-  #
-  #   Hello #{session[:person]}
-  #
-  # For removing objects from the session, you can either assign a single key to +nil+:
-  #
-  #   # removes :person from session
-  #   session[:person] = nil
-  #
-  # or you can remove the entire session with +reset_session+.
-  #
-  # Sessions are stored by default in a browser cookie that's cryptographically signed, but unencrypted.
-  # This prevents the user from tampering with the session but also allows him to see its contents.
-  #
-  # Do not put secret information in cookie-based sessions!
-  #
-  # Other options for session storage are:
-  #
-  # * ActiveRecord::SessionStore - Sessions are stored in your database, which works better than PStore with multiple app servers and,
-  #   unlike CookieStore, hides your session contents from the user. To use ActiveRecord::SessionStore, set
-  #
-  #     config.action_controller.session_store = :active_record_store
-  #
-  #   in your <tt>config/environment.rb</tt> and run <tt>rake db:sessions:create</tt>.
-  #
-  # * MemCacheStore - Sessions are stored as entries in your memcached cache.
-  #   Set the session store type in <tt>config/environment.rb</tt>:
-  #
-  #     config.action_controller.session_store = :mem_cache_store
-  #
-  #   This assumes that memcached has been installed and configured properly.
-  #   See the MemCacheStore docs for more information.
-  #
-  # == Responses
-  #
-  # Each action results in a response, which holds the headers and document to be sent to the user's browser. The actual response
-  # object is generated automatically through the use of renders and redirects and requires no user intervention.
-  #
-  # == Renders
-  #
-  # Action Controller sends content to the user by using one of five rendering methods. The most versatile and common is the rendering
-  # of a template. Included in the Action Pack is the Action View, which enables rendering of ERb templates. It's automatically configured.
-  # The controller passes objects to the view by assigning instance variables:
-  #
-  #   def show
-  #     @post = Post.find(params[:id])
-  #   end
-  #
-  # Which are then automatically available to the view:
-  #
-  #   Title: <%= @post.title %>
-  #
-  # You don't have to rely on the automated rendering. Especially actions that could result in the rendering of different templates will use
-  # the manual rendering methods:
-  #
-  #   def search
-  #     @results = Search.find(params[:query])
-  #     case @results
-  #       when 0 then render :action => "no_results"
-  #       when 1 then render :action => "show"
-  #       when 2..10 then render :action => "show_many"
-  #     end
-  #   end
-  #
-  # Read more about writing ERb and Builder templates in link:classes/ActionView/Base.html.
-  #
-  # == Redirects
-  #
-  # Redirects are used to move from one action to another. For example, after a <tt>create</tt> action, which stores a blog entry to a database,
-  # we might like to show the user the new entry. Because we're following good DRY principles (Don't Repeat Yourself), we're going to reuse (and redirect to)
-  # a <tt>show</tt> action that we'll assume has already been created. The code might look like this:
-  #
-  #   def create
-  #     @entry = Entry.new(params[:entry])
-  #     if @entry.save
-  #       # The entry was saved correctly, redirect to show
-  #       redirect_to :action => 'show', :id => @entry.id
-  #     else
-  #       # things didn't go so well, do something else
-  #     end
-  #   end
-  #
-  # In this case, after saving our new entry to the database, the user is redirected to the <tt>show</tt> method which is then executed.
-  #
-  # == Calling multiple redirects or renders
-  #
-  # An action may contain only a single render or a single redirect. Attempting to try to do either again will result in a DoubleRenderError:
-  #
-  #   def do_something
-  #     redirect_to :action => "elsewhere"
-  #     render :action => "overthere" # raises DoubleRenderError
-  #   end
-  #
-  # If you need to redirect on the condition of something, then be sure to add "and return" to halt execution.
-  #
-  #   def do_something
-  #     redirect_to(:action => "elsewhere") and return if monkeys.nil?
-  #     render :action => "overthere" # won't be called if monkeys is nil

-      # Routes composes a query string as the key/value pairs not included in the <base>.
-      #
-      # The default Routes setup supports a typical Rails path of "controller/action/id" where action and id are optional, with
-      # action defaulting to 'index' when not given. Here are some typical url_for statements and their corresponding URLs:
-      #
-      #   url_for :controller => 'posts', :action => 'recent'                # => 'proto://host.com/posts/recent'
-      #   url_for :controller => 'posts', :action => 'index'                 # => 'proto://host.com/posts'
-      #   url_for :controller => 'posts', :action => 'index', :port=>'8033'  # => 'proto://host.com:8033/posts'
-      #   url_for :controller => 'posts', :action => 'show', :id => 10       # => 'proto://host.com/posts/show/10'
-      #   url_for :controller => 'posts', :user => 'd', :password => '123'   # => 'proto://d:123@host.com/posts'
-      #
-      # When generating a new URL, missing values may be filled in from the current request's parameters. For example,
-      # <tt>url_for :action => 'some_action'</tt> will retain the current controller, as expected. This behavior extends to
-      # other parameters, including <tt>:controller</tt>, <tt>:id</tt>, and any other parameters that are placed into a Route's
-      # path.
-      #  
-      # The URL helpers such as <tt>url_for</tt> have a limited form of memory: when generating a new URL, they can look for
-      # missing values in the current request's parameters. Routes attempts to guess when a value should and should not be
-      # taken from the defaults. There are a few simple rules on how this is performed:
-      #
-      # * If the controller name begins with a slash no defaults are used:
-      #
-      #     url_for :controller => '/home'
-      #
-      #   In particular, a leading slash ensures no namespace is assumed. Thus,
-      #   while <tt>url_for :controller => 'users'</tt> may resolve to
-      #   <tt>Admin::UsersController</tt> if the current controller lives under
-      #   that module, <tt>url_for :controller => '/users'</tt> ensures you link
-      #   to <tt>::UsersController</tt> no matter what.
-      # * If the controller changes, the action will default to index unless provided
-      #
-      # The final rule is applied while the URL is being generated and is best illustrated by an example. Let us consider the
-      # route given by <tt>map.connect 'people/:last/:first/:action', :action => 'bio', :controller => 'people'</tt>.
-      #
-      # Suppose that the current URL is "people/hh/david/contacts". Let's consider a few different cases of URLs which are generated
-      # from this page.
-      #
-      # * <tt>url_for :action => 'bio'</tt> -- During the generation of this URL, default values will be used for the first and
-      # last components, and the action shall change. The generated URL will be, "people/hh/david/bio".
-      # * <tt>url_for :first => 'davids-little-brother'</tt> This generates the URL 'people/hh/davids-little-brother' -- note
-      #   that this URL leaves out the assumed action of 'bio'.
-      #
-      # However, you might ask why the action from the current request, 'contacts', isn't carried over into the new URL. The
-      # answer has to do with the order in which the parameters appear in the generated path. In a nutshell, since the
-      # value that appears in the slot for <tt>:first</tt> is not equal to default value for <tt>:first</tt> we stop using
-      # defaults. On its own, this rule can account for much of the typical Rails URL behavior.
-      #  
-      # Although a convenience, defaults can occasionally get in your way. In some cases a default persists longer than desired.
-      # The default may be cleared by adding <tt>:name => nil</tt> to <tt>url_for</tt>'s options.
-      # This is often required when writing form helpers, since the defaults in play may vary greatly depending upon where the
-      # helper is used from. The following line will redirect to PostController's default action, regardless of the page it is
-      # displayed on:
-      #
-      #   url_for :controller => 'posts', :action => nil
-      #
-      # If you explicitly want to create a URL that's almost the same as the current URL, you can do so using the
-      # <tt>:overwrite_params</tt> options. Say for your posts you have different views for showing and printing them.
-      # Then, in the show view, you get the URL for the print view like this
-      #
-      #   url_for :overwrite_params => { :action => 'print' }
-      #
-      # This takes the current URL as is and only exchanges the action. In contrast, <tt>url_for :action => 'print'</tt>
-      # would have slashed-off the path components after the changed action.
-      def url_for(options = {})

-      # Renders the content that will be returned to the browser as the response body.
-      #
-      # === Rendering an action
-      #
-      # Action rendering is the most common form and the type used automatically by Action Controller when nothing else is
-      # specified. By default, actions are rendered within the current layout (if one exists).
-      #
-      #   # Renders the template for the action "goal" within the current controller
-      #   render :action => "goal"
-      #
-      #   # Renders the template for the action "short_goal" within the current controller,
-      #   # but without the current active layout
-      #   render :action => "short_goal", :layout => false
-      #
-      #   # Renders the template for the action "long_goal" within the current controller,
-      #   # but with a custom layout
-      #   render :action => "long_goal", :layout => "spectacular"
-      #
-      # === Rendering partials
-      #
-      # Partial rendering in a controller is most commonly used together with Ajax calls that only update one or a few elements on a page
-      # without reloading. Rendering of partials from the controller makes it possible to use the same partial template in
-      # both the full-page rendering (by calling it from within the template) and when sub-page updates happen (from the
-      # controller action responding to Ajax calls). By default, the current layout is not used.
-      #
-      #   # Renders the same partial with a local variable.
-      #   render :partial => "person", :locals => { :name => "david" }
-      #
-      #   # Renders the partial, making @new_person available through
-      #   # the local variable 'person'
-      #   render :partial => "person", :object => @new_person
-      #
-      #   # Renders a collection of the same partial by making each element
-      #   # of @winners available through the local variable "person" as it
-      #   # builds the complete response.
-      #   render :partial => "person", :collection => @winners
-      #
-      #   # Renders a collection of partials but with a custom local variable name
-      #   render :partial => "admin_person", :collection => @winners, :as => :person
-      #
-      #   # Renders the same collection of partials, but also renders the
-      #   # person_divider partial between each person partial.
-      #   render :partial => "person", :collection => @winners, :spacer_template => "person_divider"
-      #
-      #   # Renders a collection of partials located in a view subfolder
-      #   # outside of our current controller.  In this example we will be
-      #   # rendering app/views/shared/_note.r(html|xml)  Inside the partial
-      #   # each element of @new_notes is available as the local var "note".
-      #   render :partial => "shared/note", :collection => @new_notes
-      #
-      #   # Renders the partial with a status code of 500 (internal error).
-      #   render :partial => "broken", :status => 500
-      #
-      # Note that the partial filename must also be a valid Ruby variable name,
-      # so e.g. 2005 and register-user are invalid.
-      #
-      #
-      # == Automatic etagging
-      #
-      # Rendering will automatically insert the etag header on 200 OK responses. The etag is calculated using MD5 of the
-      # response body. If a request comes in that has a matching etag, the response will be changed to a 304 Not Modified
-      # and the response body will be set to an empty string. No etag header will be inserted if it's already set.
-      #
-      # === Rendering a template
-      #
-      # Template rendering works just like action rendering except that it takes a path relative to the template root.
-      # The current layout is automatically applied.
-      #
-      #   # Renders the template located in [TEMPLATE_ROOT]/weblog/show.r(html|xml) (in Rails, app/views/weblog/show.erb)
-      #   render :template => "weblog/show"
-      #
-      #   # Renders the template with a local variable
-      #   render :template => "weblog/show", :locals => {:customer => Customer.new}
-      #
-      # === Rendering a file
-      #
-      # File rendering works just like action rendering except that it takes a filesystem path. By default, the path
-      # is assumed to be absolute, and the current layout is not applied.
-      #
-      #   # Renders the template located at the absolute filesystem path
-      #   render :file => "/path/to/some/template.erb"
-      #   render :file => "c:/path/to/some/template.erb"
-      #
-      #   # Renders a template within the current layout, and with a 404 status code
-      #   render :file => "/path/to/some/template.erb", :layout => true, :status => 404
-      #   render :file => "c:/path/to/some/template.erb", :layout => true, :status => 404
-      #
-      # === Rendering text
-      #
-      # Rendering of text is usually used for tests or for rendering prepared content, such as a cache. By default, text
-      # rendering is not done within the active layout.
-      #
-      #   # Renders the clear text "hello world" with status code 200
-      #   render :text => "hello world!"
-      #
-      #   # Renders the clear text "Explosion!"  with status code 500
-      #   render :text => "Explosion!", :status => 500
-      #
-      #   # Renders the clear text "Hi there!" within the current active layout (if one exists)
-      #   render :text => "Hi there!", :layout => true
-      #
-      #   # Renders the clear text "Hi there!" within the layout
-      #   # placed in "app/views/layouts/special.r(html|xml)"
-      #   render :text => "Hi there!", :layout => "special"
-      #
-      # The <tt>:text</tt> option can also accept a Proc object, which can be used to manually control the page generation. This should
-      # generally be avoided, as it violates the separation between code and content, and because almost everything that can be
-      # done with this method can also be done more cleanly using one of the other rendering methods, most notably templates.
-      #
-      #   # Renders "Hello from code!"
-      #   render :text => proc { |response, output| output.write("Hello from code!") }
-      #
-      # === Rendering XML
-      #
-      # Rendering XML sets the content type to application/xml.
-      #
-      #   # Renders '<name>David</name>'
-      #   render :xml => {:name => "David"}.to_xml
-      #
-      # It's not necessary to call <tt>to_xml</tt> on the object you want to render, since <tt>render</tt> will
-      # automatically do that for you:
-      #
-      #   # Also renders '<name>David</name>'
-      #   render :xml => {:name => "David"}
-      #
-      # === Rendering JSON
-      #
-      # Rendering JSON sets the content type to application/json and optionally wraps the JSON in a callback. It is expected
-      # that the response will be parsed (or eval'd) for use as a data structure.
-      #
-      #   # Renders '{"name": "David"}'
-      #   render :json => {:name => "David"}.to_json
-      #
-      # It's not necessary to call <tt>to_json</tt> on the object you want to render, since <tt>render</tt> will
-      # automatically do that for you:
-      #
-      #   # Also renders '{"name": "David"}'
-      #   render :json => {:name => "David"}
-      #
-      # Sometimes the result isn't handled directly by a script (such as when the request comes from a SCRIPT tag),
-      # so the <tt>:callback</tt> option is provided for these cases.
-      #
-      #   # Renders 'show({"name": "David"})'
-      #   render :json => {:name => "David"}.to_json, :callback => 'show'
-      #
-      # === Rendering an inline template
-      #
-      # Rendering of an inline template works as a cross between text and action rendering where the source for the template
-      # is supplied inline, like text, but its interpreted with ERb or Builder, like action. By default, ERb is used for rendering
-      # and the current layout is not used.
-      #
-      #   # Renders "hello, hello, hello, again"
-      #   render :inline => "<%= 'hello, ' * 3 + 'again' %>"
-      #
-      #   # Renders "<p>Good seeing you!</p>" using Builder
-      #   render :inline => "xml.p { 'Good seeing you!' }", :type => :builder
-      #
-      #   # Renders "hello david"
-      #   render :inline => "<%= 'hello ' + name %>", :locals => { :name => "david" }
-      #
-      # === Rendering inline JavaScriptGenerator page updates
-      #
-      # In addition to rendering JavaScriptGenerator page updates with Ajax in RJS templates (see ActionView::Base for details),
-      # you can also pass the <tt>:update</tt> parameter to +render+, along with a block, to render page updates inline.
-      #
-      #   render :update do |page|
-      #     page.replace_html  'user_list', :partial => 'user', :collection => @users
-      #     page.visual_effect :highlight, 'user_list'
-      #   end
-      #
-      # === Rendering vanilla JavaScript
-      #
-      # In addition to using RJS with render :update, you can also just render vanilla JavaScript with :js.
-      #
-      #   # Renders "alert('hello')" and sets the mime type to text/javascript
-      #   render :js => "alert('hello')"
-      #
-      # === Rendering with status and location headers
-      # All renders take the <tt>:status</tt> and <tt>:location</tt> options and turn them into headers. They can even be used together:
-      #
-      #   render :xml => post.to_xml, :status => :created, :location => post_url(post)
-      def render(options = nil, extra_options = {}, &block) #:doc:

+  # Action Controllers are the core of a web request in Rails. They are made up of one or more actions that are executed
+  # on request and then either render a template or redirect to another action. An action is defined as a public method
+  # on the controller, which will automatically be made accessible to the web-server through Rails Routes.
+  #
+  # A sample controller could look like this:
+  #
+  #   class GuestBookController < ActionController::Base
+  #     def index
+  #       @entries = Entry.find(:all)
+  #     end
+  #
+  #     def sign
+  #       Entry.create(params[:entry])
+  #       redirect_to :action => "index"
+  #     end
+  #   end
+  #
+  # Actions, by default, render a template in the <tt>app/views</tt> directory corresponding to the name of the controller and action
+  # after executing code in the action. For example, the +index+ action of the GuestBookController would render the
+  # template <tt>app/views/guestbook/index.erb</tt> by default after populating the <tt>@entries</tt> instance variable.
+  #
+  # Unlike index, the sign action will not render a template. After performing its main purpose (creating a
+  # new entry in the guest book), it initiates a redirect instead. This redirect works by returning an external
+  # "302 Moved" HTTP response that takes the user to the index action.
+  #
+  # The index and sign represent the two basic action archetypes used in Action Controllers. Get-and-show and do-and-redirect.
+  # Most actions are variations of these themes.
+  #
+  # == Requests
+  #
+  # Requests are processed by the Action Controller framework by extracting the value of the "action" key in the request parameters.
+  # This value should hold the name of the action to be performed. Once the action has been identified, the remaining
+  # request parameters, the session (if one is available), and the full request with all the HTTP headers are made available to
+  # the action through instance variables. Then the action is performed.
+  #
+  # The full request object is available with the request accessor and is primarily used to query for HTTP headers. These queries
+  # are made by accessing the environment hash, like this:
+  #
+  #   def server_ip
+  #     location = request.env["SERVER_ADDR"]
+  #     render :text => "This server hosted at #{location}"
+  #   end
+  #
+  # == Parameters
+  #
+  # All request parameters, whether they come from a GET or POST request, or from the URL, are available through the params method
+  # which returns a hash. For example, an action that was performed through <tt>/weblog/list?category=All&limit=5</tt> will include
+  # <tt>{ "category" => "All", "limit" => 5 }</tt> in params.
+  #
+  # It's also possible to construct multi-dimensional parameter hashes by specifying keys using brackets, such as:
+  #
+  #   <input type="text" name="post[name]" value="david">
+  #   <input type="text" name="post[address]" value="hyacintvej">
+  #
+  # A request stemming from a form holding these inputs will include <tt>{ "post" => { "name" => "david", "address" => "hyacintvej" } }</tt>.
+  # If the address input had been named "post[address][street]", the params would have included
+  # <tt>{ "post" => { "address" => { "street" => "hyacintvej" } } }</tt>. There's no limit to the depth of the nesting.
+  #
+  # == Sessions
+  #
+  # Sessions allows you to store objects in between requests. This is useful for objects that are not yet ready to be persisted,
+  # such as a Signup object constructed in a multi-paged process, or objects that don't change much and are needed all the time, such
+  # as a User object for a system that requires login. The session should not be used, however, as a cache for objects where it's likely
+  # they could be changed unknowingly. It's usually too much work to keep it all synchronized -- something databases already excel at.
+  #
+  # You can place objects in the session by using the <tt>session</tt> method, which accesses a hash:
+  #
+  #   session[:person] = Person.authenticate(user_name, password)
+  #
+  # And retrieved again through the same hash:
+  #
+  #   Hello #{session[:person]}
+  #
+  # For removing objects from the session, you can either assign a single key to +nil+:
+  #
+  #   # removes :person from session
+  #   session[:person] = nil
+  #
+  # or you can remove the entire session with +reset_session+.
+  #
+  # Sessions are stored by default in a browser cookie that's cryptographically signed, but unencrypted.
+  # This prevents the user from tampering with the session but also allows him to see its contents.
+  #
+  # Do not put secret information in cookie-based sessions!
+  #
+  # Other options for session storage are:
+  #
+  # * ActiveRecord::SessionStore - Sessions are stored in your database, which works better than PStore with multiple app servers and,
+  #   unlike CookieStore, hides your session contents from the user. To use ActiveRecord::SessionStore, set
+  #
+  #     config.action_controller.session_store = :active_record_store
+  #
+  #   in your <tt>config/environment.rb</tt> and run <tt>rake db:sessions:create</tt>.
+  #
+  # * MemCacheStore - Sessions are stored as entries in your memcached cache.
+  #   Set the session store type in <tt>config/environment.rb</tt>:
+  #
+  #     config.action_controller.session_store = :mem_cache_store
+  #
+  #   This assumes that memcached has been installed and configured properly.
+  #   See the MemCacheStore docs for more information.
+  #
+  # == Responses
+  #
+  # Each action results in a response, which holds the headers and document to be sent to the user's browser. The actual response
+  # object is generated automatically through the use of renders and redirects and requires no user intervention.
+  #
+  # == Renders
+  #
+  # Action Controller sends content to the user by using one of five rendering methods. The most versatile and common is the rendering
+  # of a template. Included in the Action Pack is the Action View, which enables rendering of ERb templates. It's automatically configured.
+  # The controller passes objects to the view by assigning instance variables:
+  #
+  #   def show
+  #     @post = Post.find(params[:id])
+  #   end
+  #
+  # Which are then automatically available to the view:
+  #
+  #   Title: <%= @post.title %>
+  #
+  # You don't have to rely on the automated rendering. Especially actions that could result in the rendering of different templates will use
+  # the manual rendering methods:
+  #
+  #   def search
+  #     @results = Search.find(params[:query])
+  #     case @results
+  #       when 0 then render :action => "no_results"
+  #       when 1 then render :action => "show"
+  #       when 2..10 then render :action => "show_many"
+  #     end
+  #   end
+  #
+  # Read more about writing ERb and Builder templates in link:classes/ActionView/Base.html.
+  #
+  # == Redirects
+  #
+  # Redirects are used to move from one action to another. For example, after a <tt>create</tt> action, which stores a blog entry to a database,
+  # we might like to show the user the new entry. Because we're following good DRY principles (Don't Repeat Yourself), we're going to reuse (and redirect to)
+  # a <tt>show</tt> action that we'll assume has already been created. The code might look like this:
+  #
+  #   def create
+  #     @entry = Entry.new(params[:entry])
+  #     if @entry.save
+  #       # The entry was saved correctly, redirect to show
+  #       redirect_to :action => 'show', :id => @entry.id
+  #     else
+  #       # things didn't go so well, do something else
+  #     end
+  #   end
+  #
+  # In this case, after saving our new entry to the database, the user is redirected to the <tt>show</tt> method which is then executed.
+  #
+  # == Calling multiple redirects or renders
+  #
+  # An action may contain only a single render or a single redirect. Attempting to try to do either again will result in a DoubleRenderError:
+  #
+  #   def do_something
+  #     redirect_to :action => "elsewhere"
+  #     render :action => "overthere" # raises DoubleRenderError
+  #   end
+  #
+  # If you need to redirect on the condition of something, then be sure to add "and return" to halt execution.
+  #
+  #   def do_something
+  #     redirect_to(:action => "elsewhere") and return if monkeys.nil?
+  #     render :action => "overthere" # won't be called if monkeys is nil
+  #   end

+      # action defaulting to 'index' when not given. Here are some typical url_for statements and their corresponding URLs:
+      #
+      #   url_for :controller => 'posts', :action => 'recent'                # => 'proto://host.com/posts/recent'
+      #   url_for :controller => 'posts', :action => 'index'                 # => 'proto://host.com/posts'
+      #   url_for :controller => 'posts', :action => 'index', :port=>'8033'  # => 'proto://host.com:8033/posts'
+      #   url_for :controller => 'posts', :action => 'show', :id => 10       # => 'proto://host.com/posts/show/10'
+      #   url_for :controller => 'posts', :user => 'd', :password => '123'   # => 'proto://d:123@host.com/posts'
+      #
+      # When generating a new URL, missing values may be filled in from the current request's parameters. For example,
+      # <tt>url_for :action => 'some_action'</tt> will retain the current controller, as expected. This behavior extends to
+      # other parameters, including <tt>:controller</tt>, <tt>:id</tt>, and any other parameters that are placed into a Route's
+      # path.
+      #  
+      # The URL helpers such as <tt>url_for</tt> have a limited form of memory: when generating a new URL, they can look for
+      # missing values in the current request's parameters. Routes attempts to guess when a value should and should not be
+      # taken from the defaults. There are a few simple rules on how this is performed:
+      #
+      # * If the controller name begins with a slash no defaults are used:
+      #
+      #     url_for :controller => '/home'
+      #
+      #   In particular, a leading slash ensures no namespace is assumed. Thus,
+      #   while <tt>url_for :controller => 'users'</tt> may resolve to
+      #   <tt>Admin::UsersController</tt> if the current controller lives under
+      #   that module, <tt>url_for :controller => '/users'</tt> ensures you link
+      #   to <tt>::UsersController</tt> no matter what.
+      # * If the controller changes, the action will default to index unless provided
+      #
+      # The final rule is applied while the URL is being generated and is best illustrated by an example. Let us consider the
+      # route given by <tt>map.connect 'people/:last/:first/:action', :action => 'bio', :controller => 'people'</tt>.
+      #
+      # Suppose that the current URL is "people/hh/david/contacts". Let's consider a few different cases of URLs which are generated
+      # from this page.
+      #
+      # * <tt>url_for :action => 'bio'</tt> -- During the generation of this URL, default values will be used for the first and
+      # last components, and the action shall change. The generated URL will be, "people/hh/david/bio".
+      # * <tt>url_for :first => 'davids-little-brother'</tt> This generates the URL 'people/hh/davids-little-brother' -- note
+      #   that this URL leaves out the assumed action of 'bio'.
+      #
+      # However, you might ask why the action from the current request, 'contacts', isn't carried over into the new URL. The
+      # answer has to do with the order in which the parameters appear in the generated path. In a nutshell, since the
+      # value that appears in the slot for <tt>:first</tt> is not equal to default value for <tt>:first</tt> we stop using
+      # defaults. On its own, this rule can account for much of the typical Rails URL behavior.
+      #  
+      # Although a convenience, defaults can occasionally get in your way. In some cases a default persists longer than desired.
+      # The default may be cleared by adding <tt>:name => nil</tt> to <tt>url_for</tt>'s options.
+      # This is often required when writing form helpers, since the defaults in play may vary greatly depending upon where the
+      # helper is used from. The following line will redirect to PostController's default action, regardless of the page it is
+      # displayed on:
+      #
+      #   url_for :controller => 'posts', :action => nil
+      #
+      # If you explicitly want to create a URL that's almost the same as the current URL, you can do so using the
+      # <tt>:overwrite_params</tt> options. Say for your posts you have different views for showing and printing them.
+      # Then, in the show view, you get the URL for the print view like this
+      #
+      #   url_for :overwrite_params => { :action => 'print' }
+      #
+      # This takes the current URL as is and only exchanges the action. In contrast, <tt>url_for :action => 'print'</tt>
+      # would have slashed-off the path components after the changed action.

+    # Filters enable controllers to run shared pre- and post-processing code for its actions. These filters can be used to do
+    # authentication, caching, or auditing before the intended action is performed. Or to do localization or output
+    # compression after the action has been performed. Filters have access to the request, response, and all the instance
+    # variables set by other filters in the chain or by the action (in the case of after filters).
+    #
+    # == Filter inheritance
+    #
+    # Controller inheritance hierarchies share filters downwards, but subclasses can also add or skip filters without
+    # affecting the superclass. For example:
+    #
+    #   class BankController < ActionController::Base
+    #     before_filter :audit
+    #
+    #     private
+    #       def audit
+    #         # record the action and parameters in an audit log
+    #       end
+    #   end
+    #
+    #   class VaultController < BankController
+    #     before_filter :verify_credentials
+    #
+    #     private
+    #       def verify_credentials
+    #         # make sure the user is allowed into the vault
+    #       end
+    #   end
+    #
+    # Now any actions performed on the BankController will have the audit method called before. On the VaultController,
+    # first the audit method is called, then the verify_credentials method. If the audit method renders or redirects, then
+    # verify_credentials and the intended action are never called.
+    #
+    # == Filter types
+    #
+    # A filter can take one of three forms: method reference (symbol), external class, or inline method (proc). The first
+    # is the most common and works by referencing a protected or private method somewhere in the inheritance hierarchy of
+    # the controller by use of a symbol. In the bank example above, both BankController and VaultController use this form.
+    #
+    # Using an external class makes for more easily reused generic filters, such as output compression. External filter classes
+    # are implemented by having a static +filter+ method on any class and then passing this class to the filter method. Example:
+    #
+    #   class OutputCompressionFilter
+    #     def self.filter(controller)
+    #       controller.response.body = compress(controller.response.body)
+    #     end
+    #   end
+    #
+    #   class NewspaperController < ActionController::Base
+    #     after_filter OutputCompressionFilter
+    #   end
+    #
+    # The filter method is passed the controller instance and is hence granted access to all aspects of the controller and can
+    # manipulate them as it sees fit.
+    #
+    # The inline method (using a proc) can be used to quickly do something small that doesn't require a lot of explanation.
+    # Or just as a quick test. It works like this:
+    #
+    #   class WeblogController < ActionController::Base
+    #     before_filter { |controller| head(400) if controller.params["stop_action"] }
+    #   end
+    #
+    # As you can see, the block expects to be passed the controller after it has assigned the request to the internal variables.
+    # This means that the block has access to both the request and response objects complete with convenience methods for params,
+    # session, template, and assigns. Note: The inline method doesn't strictly have to be a block; any object that responds to call
+    # and returns 1 or -1 on arity will do (such as a Proc or an Method object).
+    #
+    # Please note that around_filters function a little differently than the normal before and after filters with regard to filter
+    # types. Please see the section dedicated to around_filters below.
+    #
+    # == Filter chain ordering
+    #
+    # Using <tt>before_filter</tt> and <tt>after_filter</tt> appends the specified filters to the existing chain. That's usually
+    # just fine, but some times you care more about the order in which the filters are executed. When that's the case, you
+    # can use <tt>prepend_before_filter</tt> and <tt>prepend_after_filter</tt>. Filters added by these methods will be put at the
+    # beginning of their respective chain and executed before the rest. For example:
+    #
+    #   class ShoppingController < ActionController::Base
+    #     before_filter :verify_open_shop
+    #
+    #   class CheckoutController < ShoppingController
+    #     prepend_before_filter :ensure_items_in_cart, :ensure_items_in_stock
+    #
+    # The filter chain for the CheckoutController is now <tt>:ensure_items_in_cart, :ensure_items_in_stock,</tt>
+    # <tt>:verify_open_shop</tt>. So if either of the ensure filters renders or redirects, we'll never get around to see if the shop
+    # is open or not.
+    #
+    # You may pass multiple filter arguments of each type as well as a filter block.
+    # If a block is given, it is treated as the last argument.
+    #
+    # == Around filters
+    #
+    # Around filters wrap an action, executing code both before and after.
+    # They may be declared as method references, blocks, or objects responding
+    # to +filter+ or to both +before+ and +after+.
+    #
+    # To use a method as an +around_filter+, pass a symbol naming the Ruby method.
+    # Yield (or <tt>block.call</tt>) within the method to run the action.
+    #
+    #   around_filter :catch_exceptions
+    #
+    #   private
+    #     def catch_exceptions
+    #       yield
+    #     rescue => exception
+    #       logger.debug "Caught exception! #{exception}"
+    #       raise
+    #     end
+    #
+    # To use a block as an +around_filter+, pass a block taking as args both
+    # the controller and the action block. You can't call yield directly from
+    # an +around_filter+ block; explicitly call the action block instead:
+    #
+    #   around_filter do |controller, action|
+    #     logger.debug "before #{controller.action_name}"
+    #     action.call
+    #     logger.debug "after #{controller.action_name}"
+    #   end
+    #
+    # To use a filter object with +around_filter+, pass an object responding
+    # to <tt>:filter</tt> or both <tt>:before</tt> and <tt>:after</tt>. With a
+    # filter method, yield to the block as above:
+    #
+    #   around_filter BenchmarkingFilter
+    #
+    #   class BenchmarkingFilter
+    #     def self.filter(controller, &block)
+    #       Benchmark.measure(&block)
+    #     end
+    #   end
+    #
+    # With +before+ and +after+ methods:
+    #
+    #   around_filter Authorizer.new
+    #
+    #   class Authorizer
+    #     # This will run before the action. Redirecting aborts the action.
+    #     def before(controller)
+    #       unless user.authorized?
+    #         redirect_to(login_url)
+    #       end
+    #     end
+    #
+    #     # This will run after the action if and only if before did not render or redirect.
+    #     def after(controller)
+    #     end
+    #   end
+    #
+    # If the filter has +before+ and +after+ methods, the +before+ method will be
+    # called before the action. If +before+ renders or redirects, the filter chain is
+    # halted and +after+ will not be run. See Filter Chain Halting below for
+    # an example.
+    #
+    # == Filter chain skipping
+    #
+    # Declaring a filter on a base class conveniently applies to its subclasses,
+    # but sometimes a subclass should skip some of its superclass' filters:
+    #
+    #   class ApplicationController < ActionController::Base
+    #     before_filter :authenticate
+    #     around_filter :catch_exceptions
+    #   end
+    #
+    #   class WeblogController < ApplicationController
+    #     # Will run the :authenticate and :catch_exceptions filters.
+    #   end
+    #
+    #   class SignupController < ApplicationController
+    #     # Skip :authenticate, run :catch_exceptions.
+    #     skip_before_filter :authenticate
+    #   end
+    #
+    #   class ProjectsController < ApplicationController
+    #     # Skip :catch_exceptions, run :authenticate.
+    #     skip_filter :catch_exceptions
+    #   end
+    #
+    #   class ClientsController < ApplicationController
+    #     # Skip :catch_exceptions and :authenticate unless action is index.
+    #     skip_filter :catch_exceptions, :authenticate, :except => :index
+    #   end
+    #
+    # == Filter conditions
+    #
+    # Filters may be limited to specific actions by declaring the actions to
+    # include or exclude. Both options accept single actions
+    # (<tt>:only => :index</tt>) or arrays of actions
+    # (<tt>:except => [:foo, :bar]</tt>).
+    #
+    #   class Journal < ActionController::Base
+    #     # Require authentication for edit and delete.
+    #     before_filter :authorize, :only => [:edit, :delete]
+    #
+    #     # Passing options to a filter with a block.
+    #     around_filter(:except => :index) do |controller, action_block|
+    #       results = Profiler.run(&action_block)
+    #       controller.response.sub! "</body>", "#{results}</body>"
+    #     end
+    #
+    #     private
+    #       def authorize
+    #         # Redirect to login unless authenticated.
+    #       end
+    #   end
+    #
+    # == Filter Chain Halting
+    #
+    # <tt>before_filter</tt> and <tt>around_filter</tt> may halt the request
+    # before a controller action is run. This is useful, for example, to deny
+    # access to unauthenticated users or to redirect from HTTP to HTTPS.
+    # Simply call render or redirect. After filters will not be executed if the filter 
+    # chain is halted.
+    #
+    # Around filters halt the request unless the action block is called.
+    # Given these filters
+    #   after_filter :after
+    #   around_filter :around
+    #   before_filter :before
+    #
+    # The filter chain will look like:
+    #
+    #   ...
+    #   . \
+    #   .  #around (code before yield)
+    #   .  .  \
+    #   .  .  #before (actual filter code is run)
+    #   .  .  .  \
+    #   .  .  .  execute controller action
+    #   .  .  .  /
+    #   .  .  ...
+    #   .  .  /
+    #   .  #around (code after yield)
+    #   . /
+    #   #after (actual filter code is run, unless the around filter does not yield)
+    #
+    # If +around+ returns before yielding, +after+ will still not be run. The +before+
+    # filter and controller action will not be run. If +before+ renders or redirects,
+    # the second half of +around+ and will still run but +after+ and the

+    # +numbers+ and Active Record objects, to name a few. These helpers are available to all templates
+    # by default.
+    #
+    # In addition to using the standard template helpers provided in the Rails framework, creating custom helpers to
+    # extract complicated logic or reusable functionality is strongly encouraged.  By default, the controller will 
+    # include a helper whose name matches that of the controller, e.g., <tt>MyController</tt> will automatically
+    # include <tt>MyHelper</tt>.
+    # 
+    # Additional helpers can be specified using the +helper+ class method in <tt>ActionController::Base</tt> or any
+    # controller which inherits from it.
+    #
+    # ==== Examples
+    # The +to_s+ method from the Time class can be wrapped in a helper method to display a custom message if 
+    # the Time object is blank:
+    #
+    #   module FormattedTimeHelper
+    #     def format_time(time, format=:long, blank_message="&nbsp;")
+    #       time.blank? ? blank_message : time.to_s(format)
+    #     end
+    #   end
+    #
+    # FormattedTimeHelper can now be included in a controller, using the +helper+ class method:
+    #
+    #   class EventsController < ActionController::Base
+    #     helper FormattedTimeHelper
+    #     def index
+    #       @events = Event.find(:all)
+    #     end
+    #   end
+    #
+    # Then, in any view rendered by <tt>EventController</tt>, the <tt>format_time</tt> method can be called:
+    #
+    #   <% @events.each do |event| -%>
+    #     <p>
+    #       <% format_time(event.time, :short, "N/A") %> | <%= event.name %> 
+    #     </p>
+    #   <% end -%>
+    #
+    # Finally, assuming we have two event instances, one which has a time and one which does not, 
+    # the output might look like this:

+    module ClassMethods
+      # Makes all the (instance) methods in the helper module available to templates rendered through this controller.
+      # See ActionView::Helpers (link:classes/ActionView/Helpers.html) for more about making your own helper modules
+      # available to the templates.
+      def add_template_helper(helper_module) #:nodoc:
+        master_helper_module.module_eval { include helper_module }
+      end
+
+      # The +helper+ class method can take a series of helper module names, a block, or both.
+      #
+      # * <tt>*args</tt>: One or more modules, strings or symbols, or the special symbol <tt>:all</tt>.
+      # * <tt>&block</tt>: A block defining helper methods.
+      # 
+      # ==== Examples
+      # When the argument is a string or symbol, the method will provide the "_helper" suffix, require the file 
+      # and include the module in the template class.  The second form illustrates how to include custom helpers 
+      # when working with namespaced controllers, or other cases where the file containing the helper definition is not
+      # in one of Rails' standard load paths:
+      #   helper :foo             # => requires 'foo_helper' and includes FooHelper
+      #   helper 'resources/foo'  # => requires 'resources/foo_helper' and includes Resources::FooHelper
+      #
+      # When the argument is a module it will be included directly in the template class.
+      #   helper FooHelper # => includes FooHelper
+      #
+      # When the argument is the symbol <tt>:all</tt>, the controller will include all helpers beneath
+      # <tt>ActionController::Base.helpers_dir</tt> (defaults to <tt>app/helpers/**/*.rb</tt> under RAILS_ROOT).
+      #   helper :all
+      #
+      # Additionally, the +helper+ class method can receive and evaluate a block, making the methods defined available 
+      # to the template.
+      #   # One line
+      #   helper { def hello() "Hello, world!" end }
+      #   # Multi-line
+      #   helper do
+      #     def foo(bar) 
+      #       "#{bar} is the very best" 
+      #     end
+      #   end
+      # 
+      # Finally, all the above styles can be mixed together, and the +helper+ method can be invoked with a mix of
+      # +symbols+, +strings+, +modules+ and blocks.

+    end
+
+    # Layouts reverse the common pattern of including shared headers and footers in many templates to isolate changes in
+    # repeated setups. The inclusion pattern has pages that look like this:
+    #
+    #   <%= render "shared/header" %>
+    #   Hello World
+    #   <%= render "shared/footer" %>
+    #
+    # This approach is a decent way of keeping common structures isolated from the changing content, but it's verbose
+    # and if you ever want to change the structure of these two includes, you'll have to change all the templates.
+    #
+    # With layouts, you can flip it around and have the common structure know where to insert changing content. This means
+    # that the header and footer are only mentioned in one place, like this:
+    #
+    #   // The header part of this layout
+    #   <%= yield %>
+    #   // The footer part of this layout
+    #
+    # And then you have content pages that look like this:
+    #
+    #    hello world
+    #
+    # At rendering time, the content page is computed and then inserted in the layout, like this:
+    #
+    #   // The header part of this layout
+    #   hello world
+    #   // The footer part of this layout
+    #
+    # NOTE: The old notation for rendering the view from a layout was to expose the magic <tt>@content_for_layout</tt> instance
+    # variable. The preferred notation now is to use <tt>yield</tt>, as documented above.
+    #
+    # == Accessing shared variables
+    #
+    # Layouts have access to variables specified in the content pages and vice versa. This allows you to have layouts with
+    # references that won't materialize before rendering time:
+    #
+    #   <h1><%= @page_title %></h1>
+    #   <%= yield %>
+    #
+    # ...and content pages that fulfill these references _at_ rendering time:
+    #
+    #    <% @page_title = "Welcome" %>
+    #    Off-world colonies offers you a chance to start a new life
+    #
+    # The result after rendering is:
+    #
+    #   <h1>Welcome</h1>
+    #   Off-world colonies offers you a chance to start a new life
+    #
+    # == Automatic layout assignment
+    #
+    # If there is a template in <tt>app/views/layouts/</tt> with the same name as the current controller then it will be automatically
+    # set as that controller's layout unless explicitly told otherwise. Say you have a WeblogController, for example. If a template named
+    # <tt>app/views/layouts/weblog.erb</tt> or <tt>app/views/layouts/weblog.builder</tt> exists then it will be automatically set as
+    # the layout for your WeblogController. You can create a layout with the name <tt>application.erb</tt> or <tt>application.builder</tt>
+    # and this will be set as the default controller if there is no layout with the same name as the current controller and there is
+    # no layout explicitly assigned with the +layout+ method. Nested controllers use the same folder structure for automatic layout.
+    # assignment. So an Admin::WeblogController will look for a template named <tt>app/views/layouts/admin/weblog.erb</tt>.
+    # Setting a layout explicitly will always override the automatic behaviour for the controller where the layout is set.
+    # Explicitly setting the layout in a parent class, though, will not override the child class's layout assignment if the child
+    # class has a layout with the same name.
+    #
+    # == Inheritance for layouts
+    #
+    # Layouts are shared downwards in the inheritance hierarchy, but not upwards. Examples:
+    #
+    #   class BankController < ActionController::Base
+    #     layout "bank_standard"
+    #
+    #   class InformationController < BankController
+    #
+    #   class VaultController < BankController
+    #     layout :access_level_layout
+    #
+    #   class EmployeeController < BankController
+    #     layout nil
+    #
+    # The InformationController uses "bank_standard" inherited from the BankController, the VaultController overwrites
+    # and picks the layout dynamically, and the EmployeeController doesn't want to use a layout at all.
+    #
+    # == Types of layouts
+    #
+    # Layouts are basically just regular templates, but the name of this template needs not be specified statically. Sometimes
+    # you want to alternate layouts depending on runtime information, such as whether someone is logged in or not. This can
+    # be done either by specifying a method reference as a symbol or using an inline method (as a proc).
+    #
+    # The method reference is the preferred approach to variable layouts and is used like this:
+    #
+    #   class WeblogController < ActionController::Base
+    #     layout :writers_and_readers
+    #
+    #     def index
+    #       # fetching posts
+    #     end
+    #
+    #     private
+    #       def writers_and_readers
+    #         logged_in? ? "writer_layout" : "reader_layout"
+    #       end
+    #
+    # Now when a new request for the index action is processed, the layout will vary depending on whether the person accessing
+    # is logged in or not.
+    #
+    # If you want to use an inline method, such as a proc, do something like this:
+    #
+    #   class WeblogController < ActionController::Base
+    #     layout proc{ |controller| controller.logged_in? ? "writer_layout" : "reader_layout" }
+    #
+    # Of course, the most common way of specifying a layout is still just as a plain template name:
+    #
+    #   class WeblogController < ActionController::Base
+    #     layout "weblog_standard"
+    #
+    # If no directory is specified for the template name, the template will by default be looked for in <tt>app/views/layouts/</tt>.
+    # Otherwise, it will be looked up relative to the template root.
+    #
+    # == Conditional layouts
+    #
+    # If you have a layout that by default is applied to all the actions of a controller, you still have the option of rendering
+    # a given action or set of actions without a layout, or restricting a layout to only a single action or a set of actions. The
+    # <tt>:only</tt> and <tt>:except</tt> options can be passed to the layout call. For example:
+    #
+    #   class WeblogController < ActionController::Base
+    #     layout "weblog_standard", :except => :rss
+    #
+    #     # ...
+    #
+    #   end
+    #
+    # This will assign "weblog_standard" as the WeblogController's layout  except for the +rss+ action, which will not wrap a layout
+    # around the rendered view.
+    #
+    # Both the <tt>:only</tt> and <tt>:except</tt> condition can accept an arbitrary number of method references, so
+    # #<tt>:except => [ :rss, :text_only ]</tt> is valid, as is <tt>:except => :rss</tt>.
+    #
+    # == Using a different layout in the action render call
+    #
+    # If most of your actions use the same layout, it makes perfect sense to define a controller-wide layout as described above.
+    # Sometimes you'll have exceptions where one action wants to use a different layout than the rest of the controller.
+    # You can do this by passing a <tt>:layout</tt> option to the <tt>render</tt> call. For example:
+    #
+    #   class WeblogController < ActionController::Base
+    #     layout "weblog_standard"
+    #
+    #     def help
+    #       render :action => "help", :layout => "help"
+    #     end
+    #   end
+    #
+    # This will render the help action with the "help" layout instead of the controller-wide "weblog_standard" layout.
+    module ClassMethods
+      extend ActiveSupport::Memoizable
+
+      # If a layout is specified, all rendered actions will have their result rendered
+      # when the layout <tt>yield</tt>s. This layout can itself depend on instance variables assigned during action

+    
+    protected
+    # Renders the content that will be returned to the browser as the response body.
+    #
+    # === Rendering an action
+    #
+    # Action rendering is the most common form and the type used automatically by Action Controller when nothing else is
+    # specified. By default, actions are rendered within the current layout (if one exists).
+    #
+    #   # Renders the template for the action "goal" within the current controller
+    #   render :action => "goal"
+    #
+    #   # Renders the template for the action "short_goal" within the current controller,
+    #   # but without the current active layout
+    #   render :action => "short_goal", :layout => false
+    #
+    #   # Renders the template for the action "long_goal" within the current controller,
+    #   # but with a custom layout
+    #   render :action => "long_goal", :layout => "spectacular"
+    #
+    # === Rendering partials
+    #
+    # Partial rendering in a controller is most commonly used together with Ajax calls that only update one or a few elements on a page
+    # without reloading. Rendering of partials from the controller makes it possible to use the same partial template in
+    # both the full-page rendering (by calling it from within the template) and when sub-page updates happen (from the
+    # controller action responding to Ajax calls). By default, the current layout is not used.
+    #
+    #   # Renders the same partial with a local variable.
+    #   render :partial => "person", :locals => { :name => "david" }
+    #
+    #   # Renders the partial, making @new_person available through
+    #   # the local variable 'person'
+    #   render :partial => "person", :object => @new_person
+    #
+    #   # Renders a collection of the same partial by making each element
+    #   # of @winners available through the local variable "person" as it
+    #   # builds the complete response.
+    #   render :partial => "person", :collection => @winners
+    #
+    #   # Renders a collection of partials but with a custom local variable name
+    #   render :partial => "admin_person", :collection => @winners, :as => :person
+    #
+    #   # Renders the same collection of partials, but also renders the
+    #   # person_divider partial between each person partial.
+    #   render :partial => "person", :collection => @winners, :spacer_template => "person_divider"
+    #
+    #   # Renders a collection of partials located in a view subfolder
+    #   # outside of our current controller.  In this example we will be
+    #   # rendering app/views/shared/_note.r(html|xml)  Inside the partial
+    #   # each element of @new_notes is available as the local var "note".
+    #   render :partial => "shared/note", :collection => @new_notes
+    #
+    #   # Renders the partial with a status code of 500 (internal error).
+    #   render :partial => "broken", :status => 500
+    #
+    # Note that the partial filename must also be a valid Ruby variable name,
+    # so e.g. 2005 and register-user are invalid.
+    #
+    #
+    # == Automatic etagging
+    #
+    # Rendering will automatically insert the etag header on 200 OK responses. The etag is calculated using MD5 of the
+    # response body. If a request comes in that has a matching etag, the response will be changed to a 304 Not Modified
+    # and the response body will be set to an empty string. No etag header will be inserted if it's already set.
+    #
+    # === Rendering a template
+    #
+    # Template rendering works just like action rendering except that it takes a path relative to the template root.
+    # The current layout is automatically applied.
+    #
+    #   # Renders the template located in [TEMPLATE_ROOT]/weblog/show.r(html|xml) (in Rails, app/views/weblog/show.erb)
+    #   render :template => "weblog/show"
+    #
+    #   # Renders the template with a local variable
+    #   render :template => "weblog/show", :locals => {:customer => Customer.new}
+    #
+    # === Rendering a file
+    #
+    # File rendering works just like action rendering except that it takes a filesystem path. By default, the path
+    # is assumed to be absolute, and the current layout is not applied.
+    #
+    #   # Renders the template located at the absolute filesystem path
+    #   render :file => "/path/to/some/template.erb"
+    #   render :file => "c:/path/to/some/template.erb"
+    #
+    #   # Renders a template within the current layout, and with a 404 status code
+    #   render :file => "/path/to/some/template.erb", :layout => true, :status => 404
+    #   render :file => "c:/path/to/some/template.erb", :layout => true, :status => 404
+    #
+    # === Rendering text
+    #
+    # Rendering of text is usually used for tests or for rendering prepared content, such as a cache. By default, text
+    # rendering is not done within the active layout.
+    #
+    #   # Renders the clear text "hello world" with status code 200
+    #   render :text => "hello world!"
+    #
+    #   # Renders the clear text "Explosion!"  with status code 500
+    #   render :text => "Explosion!", :status => 500
+    #
+    #   # Renders the clear text "Hi there!" within the current active layout (if one exists)
+    #   render :text => "Hi there!", :layout => true
+    #
+    #   # Renders the clear text "Hi there!" within the layout
+    #   # placed in "app/views/layouts/special.r(html|xml)"
+    #   render :text => "Hi there!", :layout => "special"
+    #
+    # The <tt>:text</tt> option can also accept a Proc object, which can be used to manually control the page generation. This should
+    # generally be avoided, as it violates the separation between code and content, and because almost everything that can be
+    # done with this method can also be done more cleanly using one of the other rendering methods, most notably templates.
+    #
+    #   # Renders "Hello from code!"
+    #   render :text => proc { |response, output| output.write("Hello from code!") }
+    #
+    # === Rendering XML
+    #
+    # Rendering XML sets the content type to application/xml.
+    #
+    #   # Renders '<name>David</name>'
+    #   render :xml => {:name => "David"}.to_xml
+    #
+    # It's not necessary to call <tt>to_xml</tt> on the object you want to render, since <tt>render</tt> will
+    # automatically do that for you:
+    #
+    #   # Also renders '<name>David</name>'
+    #   render :xml => {:name => "David"}
+    #
+    # === Rendering JSON
+    #
+    # Rendering JSON sets the content type to application/json and optionally wraps the JSON in a callback. It is expected
+    # that the response will be parsed (or eval'd) for use as a data structure.
+    #
+    #   # Renders '{"name": "David"}'
+    #   render :json => {:name => "David"}.to_json
+    #
+    # It's not necessary to call <tt>to_json</tt> on the object you want to render, since <tt>render</tt> will
+    # automatically do that for you:
+    #
+    #   # Also renders '{"name": "David"}'
+    #   render :json => {:name => "David"}
+    #
+    # Sometimes the result isn't handled directly by a script (such as when the request comes from a SCRIPT tag),
+    # so the <tt>:callback</tt> option is provided for these cases.
+    #
+    #   # Renders 'show({"name": "David"})'
+    #   render :json => {:name => "David"}.to_json, :callback => 'show'
+    #
+    # === Rendering an inline template
+    #
+    # Rendering of an inline template works as a cross between text and action rendering where the source for the template
+    # is supplied inline, like text, but its interpreted with ERb or Builder, like action. By default, ERb is used for rendering
+    # and the current layout is not used.
+    #
+    #   # Renders "hello, hello, hello, again"
+    #   render :inline => "<%= 'hello, ' * 3 + 'again' %>"
+    #
+    #   # Renders "<p>Good seeing you!</p>" using Builder
+    #   render :inline => "xml.p { 'Good seeing you!' }", :type => :builder
+    #
+    #   # Renders "hello david"
+    #   render :inline => "<%= 'hello ' + name %>", :locals => { :name => "david" }
+    #
+    # === Rendering inline JavaScriptGenerator page updates
+    #
+    # In addition to rendering JavaScriptGenerator page updates with Ajax in RJS templates (see ActionView::Base for details),
+    # you can also pass the <tt>:update</tt> parameter to +render+, along with a block, to render page updates inline.
+    #
+    #   render :update do |page|
+    #     page.replace_html  'user_list', :partial => 'user', :collection => @users
+    #     page.visual_effect :highlight, 'user_list'
+    #   end
+    #
+    # === Rendering vanilla JavaScript
+    #
+    # In addition to using RJS with render :update, you can also just render vanilla JavaScript with :js.
+    #
+    #   # Renders "alert('hello')" and sets the mime type to text/javascript
+    #   render :js => "alert('hello')"
+    #
+    # === Rendering with status and location headers
+    # All renders take the <tt>:status</tt> and <tt>:location</tt> options and turn them into headers. They can even be used together:
+    #
+    #   render :xml => post.to_xml, :status => :created, :location => post_url(post)

+    # Protecting controller actions from CSRF attacks by ensuring that all forms are coming from the current web application, not a
+    # forged link from another site, is done by embedding a token based on a random string stored in the session (which an attacker wouldn't know) in all
+    # forms and Ajax requests generated by Rails and then verifying the authenticity of that token in the controller.  Only
+    # HTML/JavaScript requests are checked, so this will not protect your XML API (presumably you'll have a different authentication
+    # scheme there anyway).  Also, GET requests are not protected as these should be idempotent anyway.
+    #
+    # This is turned on with the <tt>protect_from_forgery</tt> method, which will check the token and raise an
+    # ActionController::InvalidAuthenticityToken if it doesn't match what was expected. You can customize the error message in
+    # production by editing public/422.html.  A call to this method in ApplicationController is generated by default in post-Rails 2.0
+    # applications.
+    #
+    # The token parameter is named <tt>authenticity_token</tt> by default. If you are generating an HTML form manually (without the
+    # use of Rails' <tt>form_for</tt>, <tt>form_tag</tt> or other helpers), you have to include a hidden field named like that and
+    # set its value to what is returned by <tt>form_authenticity_token</tt>. Same applies to manually constructed Ajax requests. To
+    # make the token available through a global variable to scripts on a certain page, you could add something like this to a view:
+    #
+    #   <%= javascript_tag "window._token = '#{form_authenticity_token}'" %>
+    #
+    # Request forgery protection is disabled by default in test environment.  If you are upgrading from Rails 1.x, add this to
+    # config/environments/test.rb:
+    #
+    #   # Disable request forgery protection in test environment

+    # This module provides a class-level method for specifying that certain
+    # actions are guarded against being called without certain prerequisites
+    # being met. This is essentially a special kind of before_filter.
+    #
+    # An action may be guarded against being invoked without certain request
+    # parameters being set, or without certain session values existing.
+    #
+    # When a verification is violated, values may be inserted into the flash, and
+    # a specified redirection is triggered. If no specific action is configured,
+    # verification failures will by default result in a 400 Bad Request response.
+    #
+    # Usage:
+    #
+    #   class GlobalController < ActionController::Base
+    #     # Prevent the #update_settings action from being invoked unless
+    #     # the 'admin_privileges' request parameter exists. The
+    #     # settings action will be redirected to in current controller
+    #     # if verification fails.
+    #     verify :params => "admin_privileges", :only => :update_post,
+    #            :redirect_to => { :action => "settings" }
+    #
+    #     # Disallow a post from being updated if there was no information
+    #     # submitted with the post, and if there is no active post in the
+    #     # session, and if there is no "note" key in the flash. The route
+    #     # named category_url will be redirected to if verification fails.
+    #
+    #     verify :params => "post", :session => "post", "flash" => "note",
+    #            :only => :update_post,
+    #            :add_flash => { "alert" => "Failed to create your message" },
+    #            :redirect_to => :category_url
+    #
+    # Note that these prerequisites are not business rules. They do not examine 
+    # the content of the session or the parameters. That level of validation should
+    # be encapsulated by your domain model or helper methods in the controller.
+    module ClassMethods
+      # Verify the given actions so that if certain prerequisites are not met,

+  # Actions that fail to perform as expected throw exceptions. These
+  # exceptions can either be rescued for the public view (with a nice
+  # user-friendly explanation) or for the developers view (with tons of
+  # debugging information). The developers view is already implemented by
+  # the Action Controller, but the public view should be tailored to your
+  # specific application.
+  #
+  # The default behavior for public exceptions is to render a static html
+  # file with the name of the error code thrown.  If no such file exists, an
+  # empty response is sent with the correct status code.
+  #
+  # You can override what constitutes a local request by overriding the
+  # <tt>local_request?</tt> method in your own controller. Custom rescue
+  # behavior is achieved by overriding the <tt>rescue_action_in_public</tt>
+  # and <tt>rescue_action_locally</tt> methods.

+module ActionController # :nodoc:
+  # Represents an HTTP response generated by a controller action. One can use
+  # an ActionController::Response object to retrieve the current state
+  # of the response, or customize the response. An Response object can
+  # either represent a "real" HTTP response (i.e. one that is meant to be sent
+  # back to the web browser) or a test response (i.e. one that is generated
+  # from integration tests). See CgiResponse and TestResponse, respectively.
+  #
+  # Response is mostly a Ruby on Rails framework implement detail, and
+  # should never be used directly in controllers. Controllers should use the
+  # methods defined in ActionController::Base instead. For example, if you want
+  # to set the HTTP response's content MIME type, then use
+  # ActionControllerBase#headers instead of Response#headers.
+  #
+  # Nevertheless, integration tests may want to inspect controller responses in
+  # more detail, and that's when Response can be useful for application
+  # developers. Integration test methods such as
+  # ActionController::Integration::Session#get and
+  # ActionController::Integration::Session#post return objects of type
+  # TestResponse (which are of course also of type Response).
+  #
+  # For example, the following demo integration "test" prints the body of the
+  # controller response to the console:
+  #
+  #  class DemoControllerTest < ActionController::IntegrationTest
+  #    def test_print_root_path_to_console

-    # Filters enable controllers to run shared pre- and post-processing code for its actions. These filters can be used to do
-    # authentication, caching, or auditing before the intended action is performed. Or to do localization or output
-    # compression after the action has been performed. Filters have access to the request, response, and all the instance
-    # variables set by other filters in the chain or by the action (in the case of after filters).
-    #
-    # == Filter inheritance
-    #
-    # Controller inheritance hierarchies share filters downwards, but subclasses can also add or skip filters without
-    # affecting the superclass. For example:
-    #
-    #   class BankController < ActionController::Base
-    #     before_filter :audit
-    #
-    #     private
-    #       def audit
-    #         # record the action and parameters in an audit log
-    #       end
-    #   end
-    #
-    #   class VaultController < BankController
-    #     before_filter :verify_credentials
-    #
-    #     private
-    #       def verify_credentials
-    #         # make sure the user is allowed into the vault
-    #       end
-    #   end
-    #
-    # Now any actions performed on the BankController will have the audit method called before. On the VaultController,
-    # first the audit method is called, then the verify_credentials method. If the audit method renders or redirects, then
-    # verify_credentials and the intended action are never called.
-    #
-    # == Filter types
-    #
-    # A filter can take one of three forms: method reference (symbol), external class, or inline method (proc). The first
-    # is the most common and works by referencing a protected or private method somewhere in the inheritance hierarchy of
-    # the controller by use of a symbol. In the bank example above, both BankController and VaultController use this form.
-    #
-    # Using an external class makes for more easily reused generic filters, such as output compression. External filter classes
-    # are implemented by having a static +filter+ method on any class and then passing this class to the filter method. Example:
-    #
-    #   class OutputCompressionFilter
-    #     def self.filter(controller)
-    #       controller.response.body = compress(controller.response.body)
-    #     end
-    #   end
-    #
-    #   class NewspaperController < ActionController::Base
-    #     after_filter OutputCompressionFilter
-    #   end
-    #
-    # The filter method is passed the controller instance and is hence granted access to all aspects of the controller and can
-    # manipulate them as it sees fit.
-    #
-    # The inline method (using a proc) can be used to quickly do something small that doesn't require a lot of explanation.
-    # Or just as a quick test. It works like this:
-    #
-    #   class WeblogController < ActionController::Base
-    #     before_filter { |controller| head(400) if controller.params["stop_action"] }
-    #   end
-    #
-    # As you can see, the block expects to be passed the controller after it has assigned the request to the internal variables.
-    # This means that the block has access to both the request and response objects complete with convenience methods for params,
-    # session, template, and assigns. Note: The inline method doesn't strictly have to be a block; any object that responds to call
-    # and returns 1 or -1 on arity will do (such as a Proc or an Method object).
-    #
-    # Please note that around_filters function a little differently than the normal before and after filters with regard to filter
-    # types. Please see the section dedicated to around_filters below.
-    #
-    # == Filter chain ordering
-    #
-    # Using <tt>before_filter</tt> and <tt>after_filter</tt> appends the specified filters to the existing chain. That's usually
-    # just fine, but some times you care more about the order in which the filters are executed. When that's the case, you
-    # can use <tt>prepend_before_filter</tt> and <tt>prepend_after_filter</tt>. Filters added by these methods will be put at the
-    # beginning of their respective chain and executed before the rest. For example:
-    #
-    #   class ShoppingController < ActionController::Base
-    #     before_filter :verify_open_shop
-    #
-    #   class CheckoutController < ShoppingController
-    #     prepend_before_filter :ensure_items_in_cart, :ensure_items_in_stock
-    #
-    # The filter chain for the CheckoutController is now <tt>:ensure_items_in_cart, :ensure_items_in_stock,</tt>
-    # <tt>:verify_open_shop</tt>. So if either of the ensure filters renders or redirects, we'll never get around to see if the shop
-    # is open or not.
-    #
-    # You may pass multiple filter arguments of each type as well as a filter block.
-    # If a block is given, it is treated as the last argument.
-    #
-    # == Around filters
-    #
-    # Around filters wrap an action, executing code both before and after.
-    # They may be declared as method references, blocks, or objects responding
-    # to +filter+ or to both +before+ and +after+.
-    #
-    # To use a method as an +around_filter+, pass a symbol naming the Ruby method.
-    # Yield (or <tt>block.call</tt>) within the method to run the action.
-    #
-    #   around_filter :catch_exceptions
-    #
-    #   private
-    #     def catch_exceptions
-    #       yield
-    #     rescue => exception
-    #       logger.debug "Caught exception! #{exception}"
-    #       raise
-    #     end
-    #
-    # To use a block as an +around_filter+, pass a block taking as args both
-    # the controller and the action block. You can't call yield directly from
-    # an +around_filter+ block; explicitly call the action block instead:
-    #
-    #   around_filter do |controller, action|
-    #     logger.debug "before #{controller.action_name}"
-    #     action.call
-    #     logger.debug "after #{controller.action_name}"
-    #   end
-    #
-    # To use a filter object with +around_filter+, pass an object responding
-    # to <tt>:filter</tt> or both <tt>:before</tt> and <tt>:after</tt>. With a
-    # filter method, yield to the block as above:
-    #
-    #   around_filter BenchmarkingFilter
-    #
-    #   class BenchmarkingFilter
-    #     def self.filter(controller, &block)
-    #       Benchmark.measure(&block)
-    #     end
-    #   end
-    #
-    # With +before+ and +after+ methods:
-    #
-    #   around_filter Authorizer.new
-    #
-    #   class Authorizer
-    #     # This will run before the action. Redirecting aborts the action.
-    #     def before(controller)
-    #       unless user.authorized?
-    #         redirect_to(login_url)
-    #       end
-    #     end
-    #
-    #     # This will run after the action if and only if before did not render or redirect.
-    #     def after(controller)
-    #     end
-    #   end
-    #
-    # If the filter has +before+ and +after+ methods, the +before+ method will be
-    # called before the action. If +before+ renders or redirects, the filter chain is
-    # halted and +after+ will not be run. See Filter Chain Halting below for
-    # an example.
-    #
-    # == Filter chain skipping
-    #
-    # Declaring a filter on a base class conveniently applies to its subclasses,
-    # but sometimes a subclass should skip some of its superclass' filters:
-    #
-    #   class ApplicationController < ActionController::Base
-    #     before_filter :authenticate
-    #     around_filter :catch_exceptions
-    #   end
-    #
-    #   class WeblogController < ApplicationController
-    #     # Will run the :authenticate and :catch_exceptions filters.
-    #   end
-    #
-    #   class SignupController < ApplicationController
-    #     # Skip :authenticate, run :catch_exceptions.
-    #     skip_before_filter :authenticate
-    #   end
-    #
-    #   class ProjectsController < ApplicationController
-    #     # Skip :catch_exceptions, run :authenticate.
-    #     skip_filter :catch_exceptions
-    #   end
-    #
-    #   class ClientsController < ApplicationController
-    #     # Skip :catch_exceptions and :authenticate unless action is index.
-    #     skip_filter :catch_exceptions, :authenticate, :except => :index
-    #   end
-    #
-    # == Filter conditions
-    #
-    # Filters may be limited to specific actions by declaring the actions to
-    # include or exclude. Both options accept single actions
-    # (<tt>:only => :index</tt>) or arrays of actions
-    # (<tt>:except => [:foo, :bar]</tt>).
-    #

-    # == Filter Chain Halting
-    #
-    # <tt>before_filter</tt> and <tt>around_filter</tt> may halt the request
-    # before a controller action is run. This is useful, for example, to deny
-    # access to unauthenticated users or to redirect from HTTP to HTTPS.
-    # Simply call render or redirect. After filters will not be executed if the filter 
-    # chain is halted.
-    #
-    # Around filters halt the request unless the action block is called.
-    # Given these filters
-    #   after_filter :after
-    #   around_filter :around
-    #   before_filter :before
-    #
-    # The filter chain will look like:
-    #
-    #   ...
-    #   . \
-    #   .  #around (code before yield)
-    #   .  .  \
-    #   .  .  #before (actual filter code is run)

-    #   .  #around (code after yield)
-    #   . /
-    #   #after (actual filter code is run, unless the around filter does not yield)
-    #
-    # If +around+ returns before yielding, +after+ will still not be run. The +before+
-    # filter and controller action will not be run. If +before+ renders or redirects,
-    # the second half of +around+ and will still run but +after+ and the

-    #     def index

-      # See ActionView::Helpers (link:classes/ActionView/Helpers.html) for more about making your own helper modules

-        master_helper_module.module_eval { include helper_module }

-
-      # The +helper+ class method can take a series of helper module names, a block, or both.
-      #
-      # * <tt>*args</tt>: One or more modules, strings or symbols, or the special symbol <tt>:all</tt>.
-      # * <tt>&block</tt>: A block defining helper methods.
-      # 
-      # ==== Examples
-      # When the argument is a string or symbol, the method will provide the "_helper" suffix, require the file 
-      # and include the module in the template class.  The second form illustrates how to include custom helpers 
-      # when working with namespaced controllers, or other cases where the file containing the helper definition is not
-      # in one of Rails' standard load paths:
-      #   helper :foo             # => requires 'foo_helper' and includes FooHelper
-      #   helper 'resources/foo'  # => requires 'resources/foo_helper' and includes Resources::FooHelper
-      #
-      # When the argument is a module it will be included directly in the template class.
-      #   helper FooHelper # => includes FooHelper
-      #
-      # When the argument is the symbol <tt>:all</tt>, the controller will include all helpers beneath
-      # <tt>ActionController::Base.helpers_dir</tt> (defaults to <tt>app/helpers/**/*.rb</tt> under RAILS_ROOT).
-      #   helper :all
-      #
-      # Additionally, the +helper+ class method can receive and evaluate a block, making the methods defined available 
-      # to the template.
-      #   # One line
-      #   helper { def hello() "Hello, world!" end }
-      #   # Multi-line
-      #   helper do
-      #     def foo(bar) 
-      #       "#{bar} is the very best" 
-      #     end
-      #   end
-      # 
-      # Finally, all the above styles can be mixed together, and the +helper+ method can be invoked with a mix of
-      # +symbols+, +strings+, +modules+ and blocks.

-
-    # Layouts reverse the common pattern of including shared headers and footers in many templates to isolate changes in
-    # repeated setups. The inclusion pattern has pages that look like this:
-    #
-    #   <%= render "shared/header" %>
-    #   Hello World
-    #   <%= render "shared/footer" %>
-    #
-    # This approach is a decent way of keeping common structures isolated from the changing content, but it's verbose
-    # and if you ever want to change the structure of these two includes, you'll have to change all the templates.
-    #
-    # With layouts, you can flip it around and have the common structure know where to insert changing content. This means
-    # that the header and footer are only mentioned in one place, like this:
-    #
-    #   // The header part of this layout
-    #   <%= yield %>
-    #   // The footer part of this layout
-    #
-    # And then you have content pages that look like this:
-    #
-    #    hello world
-    #
-    # At rendering time, the content page is computed and then inserted in the layout, like this:
-    #
-    #   // The header part of this layout
-    #   hello world
-    #   // The footer part of this layout
-    #
-    # NOTE: The old notation for rendering the view from a layout was to expose the magic <tt>@content_for_layout</tt> instance
-    # variable. The preferred notation now is to use <tt>yield</tt>, as documented above.
-    #
-    # == Accessing shared variables
-    #
-    # Layouts have access to variables specified in the content pages and vice versa. This allows you to have layouts with
-    # references that won't materialize before rendering time:
-    #
-    #   <h1><%= @page_title %></h1>
-    #   <%= yield %>
-    #
-    # ...and content pages that fulfill these references _at_ rendering time:
-    #
-    #    <% @page_title = "Welcome" %>
-    #    Off-world colonies offers you a chance to start a new life
-    #
-    # The result after rendering is:
-    #
-    #   <h1>Welcome</h1>
-    #   Off-world colonies offers you a chance to start a new life
-    #
-    # == Automatic layout assignment
-    #
-    # If there is a template in <tt>app/views/layouts/</tt> with the same name as the current controller then it will be automatically
-    # set as that controller's layout unless explicitly told otherwise. Say you have a WeblogController, for example. If a template named
-    # <tt>app/views/layouts/weblog.erb</tt> or <tt>app/views/layouts/weblog.builder</tt> exists then it will be automatically set as
-    # the layout for your WeblogController. You can create a layout with the name <tt>application.erb</tt> or <tt>application.builder</tt>
-    # and this will be set as the default controller if there is no layout with the same name as the current controller and there is
-    # no layout explicitly assigned with the +layout+ method. Nested controllers use the same folder structure for automatic layout.
-    # assignment. So an Admin::WeblogController will look for a template named <tt>app/views/layouts/admin/weblog.erb</tt>.
-    # Setting a layout explicitly will always override the automatic behaviour for the controller where the layout is set.
-    # Explicitly setting the layout in a parent class, though, will not override the child class's layout assignment if the child
-    # class has a layout with the same name.
-    #
-    # == Inheritance for layouts
-    #
-    # Layouts are shared downwards in the inheritance hierarchy, but not upwards. Examples:
-    #
-    #   class BankController < ActionController::Base
-    #     layout "bank_standard"
-    #
-    #   class InformationController < BankController
-    #
-    #   class VaultController < BankController
-    #     layout :access_level_layout
-    #
-    #   class EmployeeController < BankController
-    #     layout nil
-    #
-    # The InformationController uses "bank_standard" inherited from the BankController, the VaultController overwrites
-    # and picks the layout dynamically, and the EmployeeController doesn't want to use a layout at all.
-    #
-    # == Types of layouts
-    #
-    # Layouts are basically just regular templates, but the name of this template needs not be specified statically. Sometimes
-    # you want to alternate layouts depending on runtime information, such as whether someone is logged in or not. This can
-    # be done either by specifying a method reference as a symbol or using an inline method (as a proc).
-    #
-    # The method reference is the preferred approach to variable layouts and is used like this:
-    #
-    #   class WeblogController < ActionController::Base
-    #     layout :writers_and_readers
-    #
-    #     def index
-    #       # fetching posts
-    #     end
-    #
-    #     private
-    #       def writers_and_readers
-    #         logged_in? ? "writer_layout" : "reader_layout"
-    #       end
-    #
-    # Now when a new request for the index action is processed, the layout will vary depending on whether the person accessing
-    # is logged in or not.
-    #
-    # If you want to use an inline method, such as a proc, do something like this:
-    #
-    #   class WeblogController < ActionController::Base
-    #     layout proc{ |controller| controller.logged_in? ? "writer_layout" : "reader_layout" }
-    #
-    # Of course, the most common way of specifying a layout is still just as a plain template name:
-    #
-    #   class WeblogController < ActionController::Base
-    #     layout "weblog_standard"
-    #
-    # If no directory is specified for the template name, the template will by default be looked for in <tt>app/views/layouts/</tt>.
-    # Otherwise, it will be looked up relative to the template root.
-    #
-    # == Conditional layouts
-    #
-    # If you have a layout that by default is applied to all the actions of a controller, you still have the option of rendering
-    # a given action or set of actions without a layout, or restricting a layout to only a single action or a set of actions. The
-    # <tt>:only</tt> and <tt>:except</tt> options can be passed to the layout call. For example:
-    #
-    #   class WeblogController < ActionController::Base
-    #     layout "weblog_standard", :except => :rss
-    #
-    #     # ...
-    #
-    #   end
-    #
-    # This will assign "weblog_standard" as the WeblogController's layout  except for the +rss+ action, which will not wrap a layout
-    # around the rendered view.
-    #
-    # Both the <tt>:only</tt> and <tt>:except</tt> condition can accept an arbitrary number of method references, so
-    # #<tt>:except => [ :rss, :text_only ]</tt> is valid, as is <tt>:except => :rss</tt>.
-    #
-    # == Using a different layout in the action render call
-    #
-    # If most of your actions use the same layout, it makes perfect sense to define a controller-wide layout as described above.
-    # Sometimes you'll have exceptions where one action wants to use a different layout than the rest of the controller.
-    # You can do this by passing a <tt>:layout</tt> option to the <tt>render</tt> call. For example:
-    #
-    #   class WeblogController < ActionController::Base
-    #     layout "weblog_standard"
-    #
-    #     def help
-    #       render :action => "help", :layout => "help"
-    #     end
-    #   end
-    #
-    # This will render the help action with the "help" layout instead of the controller-wide "weblog_standard" layout.
-    module ClassMethods
-      extend ActiveSupport::Memoizable
-
-      # If a layout is specified, all rendered actions will have their result rendered
-      # when the layout <tt>yield</tt>s. This layout can itself depend on instance variables assigned during action
-      # performance and have access to them as any normal template would.

-module ActionController
-  # Polymorphic URL helpers are methods for smart resolution to a named route call when
-  # given an Active Record model instance. They are to be used in combination with
-  # ActionController::Resources.
-  #
-  # These methods are useful when you want to generate correct URL or path to a RESTful
-  # resource without having to know the exact type of the record in question.
-  #
-  # Nested resources and/or namespaces are also supported, as illustrated in the example:
-  #
-  #   polymorphic_url([:admin, @article, @comment])
-  #
-  # results in:
-  #   
-  #   admin_article_comment_url(@article, @comment)
-  #
-  # == Usage within the framework
-  #
-  # Polymorphic URL helpers are used in a number of places throughout the Rails framework:
-  #
-  # * <tt>url_for</tt>, so you can use it with a record as the argument, e.g.
-  #   <tt>url_for(@article)</tt>;
-  # * ActionView::Helpers::FormHelper uses <tt>polymorphic_path</tt>, so you can write
-  #   <tt>form_for(@article)</tt> without having to specify <tt>:url</tt> parameter for the form
-  #   action;
-  # * <tt>redirect_to</tt> (which, in fact, uses <tt>url_for</tt>) so you can write
-  #   <tt>redirect_to(post)</tt> in your controllers;
-  # * ActionView::Helpers::AtomFeedHelper, so you don't have to explicitly specify URLs
-  #   for feed entries.
-  #
-  # == Prefixed polymorphic helpers
-  #
-  # In addition to <tt>polymorphic_url</tt> and <tt>polymorphic_path</tt> methods, a
-  # number of prefixed helpers are available as a shorthand to <tt>:action => "..."</tt>
-  # in options. Those are:
-  #
-  # * <tt>edit_polymorphic_url</tt>, <tt>edit_polymorphic_path</tt>
-  # * <tt>new_polymorphic_url</tt>, <tt>new_polymorphic_path</tt>
-  #
-  # Example usage:
-  #
-  #   edit_polymorphic_path(@post)              # => "/posts/1/edit"
-  #   polymorphic_path(@post, :format => :pdf)  # => "/posts/1.pdf"
-  module PolymorphicRoutes
-    # Constructs a call to a named RESTful route for the given record and returns the
-    # resulting URL string. For example:
-    #
-    #   # calls post_url(post)
-    #   polymorphic_url(post) # => "http://example.com/posts/1"
-    #   polymorphic_url([blog, post]) # => "http://example.com/blogs/1/posts/1"
-    #   polymorphic_url([:admin, blog, post]) # => "http://example.com/admin/blogs/1/posts/1"
-    #   polymorphic_url([user, :blog, post]) # => "http://example.com/users/1/blog/posts/1"
-    #
-    # ==== Options
-    #
-    # * <tt>:action</tt> - Specifies the action prefix for the named route:
-    #   <tt>:new</tt> or <tt>:edit</tt>. Default is no prefix.
-    # * <tt>:routing_type</tt> - Allowed values are <tt>:path</tt> or <tt>:url</tt>.
-    #   Default is <tt>:url</tt>.
-    #
-    # ==== Examples
-    #
-    #   # an Article record
-    #   polymorphic_url(record)  # same as article_url(record)
-    #
-    #   # a Comment record

-    # Protecting controller actions from CSRF attacks by ensuring that all forms are coming from the current web application, not a
-    # forged link from another site, is done by embedding a token based on a random string stored in the session (which an attacker wouldn't know) in all
-    # forms and Ajax requests generated by Rails and then verifying the authenticity of that token in the controller.  Only
-    # HTML/JavaScript requests are checked, so this will not protect your XML API (presumably you'll have a different authentication
-    # scheme there anyway).  Also, GET requests are not protected as these should be idempotent anyway.
-    #
-    # This is turned on with the <tt>protect_from_forgery</tt> method, which will check the token and raise an
-    # ActionController::InvalidAuthenticityToken if it doesn't match what was expected. You can customize the error message in
-    # production by editing public/422.html.  A call to this method in ApplicationController is generated by default in post-Rails 2.0
-    # applications.
-    #
-    # The token parameter is named <tt>authenticity_token</tt> by default. If you are generating an HTML form manually (without the
-    # use of Rails' <tt>form_for</tt>, <tt>form_tag</tt> or other helpers), you have to include a hidden field named like that and
-    # set its value to what is returned by <tt>form_authenticity_token</tt>. Same applies to manually constructed Ajax requests. To
-    # make the token available through a global variable to scripts on a certain page, you could add something like this to a view:
-    #
-    #   <%= javascript_tag "window._token = '#{form_authenticity_token}'" %>
-    #
-    # Request forgery protection is disabled by default in test environment.  If you are upgrading from Rails 1.x, add this to
-    # config/environments/test.rb:
-    #
-    #   # Disable request forgery protection in test environment

-module ActionController
-  # == Overview
-  #
-  # ActionController::Resources are a way of defining RESTful \resources.  A RESTful \resource, in basic terms,
-  # is something that can be pointed at and it will respond with a representation of the data requested.
-  # In real terms this could mean a user with a browser requests an HTML page, or that a desktop application
-  # requests XML data.
-  #
-  # RESTful design is based on the assumption that there are four generic verbs that a user of an
-  # application can request from a \resource (the noun).
-  #
-  # \Resources can be requested using four basic HTTP verbs (GET, POST, PUT, DELETE), the method used
-  # denotes the type of action that should take place.
-  #
-  # === The Different Methods and their Usage
-  #
-  # * GET    - Requests for a \resource, no saving or editing of a \resource should occur in a GET request.
-  # * POST   - Creation of \resources.
-  # * PUT    - Editing of attributes on a \resource.
-  # * DELETE - Deletion of a \resource.
-  #
-  # === Examples
-  #
-  #   # A GET request on the Posts resource is asking for all Posts
-  #   GET /posts
-  #
-  #   # A GET request on a single Post resource is asking for that particular Post
-  #   GET /posts/1
-  #
-  #   # A POST request on the Posts resource is asking for a Post to be created with the supplied details
-  #   POST /posts # with => { :post => { :title => "My Whizzy New Post", :body => "I've got a brand new combine harvester" } }
-  #
-  #   # A PUT request on a single Post resource is asking for a Post to be updated
-  #   PUT /posts # with => { :id => 1, :post => { :title => "Changed Whizzy Title" } }
-  #
-  #   # A DELETE request on a single Post resource is asking for it to be deleted
-  #   DELETE /posts # with => { :id => 1 }
-  #
-  # By using the REST convention, users of our application can assume certain things about how the data
-  # is requested and how it is returned.  Rails simplifies the routing part of RESTful design by
-  # supplying you with methods to create them in your routes.rb file.

-    #
-    # will map the following actions in the corresponding controller:
-    #

-    #
-    # Along with the routes themselves, +resources+ generates named routes for use in
-    # controllers and views. <tt>map.resources :messages</tt> produces the following named routes and helpers:
-    #
-    #   Named Route   Helpers
-    #   ============  =====================================================
-    #   messages      messages_url, hash_for_messages_url,
-    #                 messages_path, hash_for_messages_path
-    #
-    #   message       message_url(id), hash_for_message_url(id),
-    #                 message_path(id), hash_for_message_path(id)
-    #
-    #   new_message   new_message_url, hash_for_new_message_url,
-    #                 new_message_path, hash_for_new_message_path
-    #
-    #   edit_message  edit_message_url(id), hash_for_edit_message_url(id),
-    #                 edit_message_path(id), hash_for_edit_message_path(id)
-    #
-    # You can use these helpers instead of +url_for+ or methods that take +url_for+ parameters. For example:
-    #
-    #   redirect_to :controller => 'messages', :action => 'index'
-    #   # and
-    #   <%= link_to "edit this message", :controller => 'messages', :action => 'edit', :id => @message.id %>
-    #
-    # now become:
-    #
-    #   redirect_to messages_url
-    #   # and
-    #   <%= link_to "edit this message", edit_message_url(@message) # calls @message.id automatically
-    #
-    # Since web browsers don't support the PUT and DELETE verbs, you will need to add a parameter '_method' to your
-    # form tags. The form helpers make this a little easier. For an update form with a <tt>@message</tt> object:
-    #
-    #   <%= form_tag message_path(@message), :method => :put %>
-    #
-    # or
-    #
-    #   <% form_for :message, @message, :url => message_path(@message), :html => {:method => :put} do |f| %>
-    #
-    # or
-    #
-    #   <% form_for @message do |f| %>
-    #
-    # which takes into account whether <tt>@message</tt> is a new record or not and generates the
-    # path and method accordingly.
-    #
-    # The +resources+ method accepts the following options to customize the resulting routes:
-    # * <tt>:collection</tt> - Add named routes for other actions that operate on the collection.
-    #   Takes a hash of <tt>#{action} => #{method}</tt>, where method is <tt>:get</tt>/<tt>:post</tt>/<tt>:put</tt>/<tt>:delete</tt>,
-    #   an array of any of the previous, or <tt>:any</tt> if the method does not matter.
-    #   These routes map to a URL like /messages/rss, with a route of +rss_messages_url+.
-    # * <tt>:member</tt> - Same as <tt>:collection</tt>, but for actions that operate on a specific member.
-    # * <tt>:new</tt> - Same as <tt>:collection</tt>, but for actions that operate on the new \resource action.
-    # * <tt>:controller</tt> - Specify the controller name for the routes.
-    # * <tt>:singular</tt> - Specify the singular name used in the member routes.
-    # * <tt>:requirements</tt> - Set custom routing parameter requirements; this is a hash of either 
-    #     regular expressions (which must match for the route to match) or extra parameters. For example:
-    #
-    #       map.resource :profile, :path_prefix => ':name', :requirements => { :name => /[a-zA-Z]+/, :extra => 'value' }
-    #
-    #     will only match if the first part is alphabetic, and will pass the parameter :extra to the controller.
-    # * <tt>:conditions</tt> - Specify custom routing recognition conditions.  \Resources sets the <tt>:method</tt> value for the method-specific routes.
-    # * <tt>:as</tt> - Specify a different \resource name to use in the URL path. For example:
-    #     # products_path == '/productos'
-    #     map.resources :products, :as => 'productos' do |product|
-    #       # product_reviews_path(product) == '/productos/1234/comentarios'
-    #       product.resources :product_reviews, :as => 'comentarios'
-    #     end
-    #
-    # * <tt>:has_one</tt> - Specify nested \resources, this is a shorthand for mapping singleton \resources beneath the current.
-    # * <tt>:has_many</tt> - Same has <tt>:has_one</tt>, but for plural \resources.
-    #
-    #   You may directly specify the routing association with +has_one+ and +has_many+ like:
-    #
-    #     map.resources :notes, :has_one => :author, :has_many => [:comments, :attachments]
-    #
-    #   This is the same as:
-    #
-    #     map.resources :notes do |notes|
-    #       notes.resource  :author
-    #       notes.resources :comments
-    #       notes.resources :attachments
-    #     end
-    #
-    # * <tt>:path_names</tt> - Specify different names for the 'new' and 'edit' actions. For example:
-    #     # new_products_path == '/productos/nuevo'
-    #     map.resources :products, :as => 'productos', :path_names => { :new => 'nuevo', :edit => 'editar' }
-    #
-    #   You can also set default action names from an environment, like this:
-    #     config.action_controller.resources_path_names = { :new => 'nuevo', :edit => 'editar' }
-    #
-    # * <tt>:path_prefix</tt> - Set a prefix to the routes with required route variables.
-    #
-    #   Weblog comments usually belong to a post, so you might use +resources+ like:
-    #
-    #     map.resources :articles
-    #     map.resources :comments, :path_prefix => '/articles/:article_id'
-    #
-    #   You can nest +resources+ calls to set this automatically:
-    #
-    #     map.resources :articles do |article|
-    #       article.resources :comments
-    #     end
-    #
-    #   The comment \resources work the same, but must now include a value for <tt>:article_id</tt>.
-    #
-    #     article_comments_url(@article)
-    #     article_comment_url(@article, @comment)
-    #
-    #     article_comments_url(:article_id => @article)
-    #     article_comment_url(:article_id => @article, :id => @comment)
-    #
-    #   If you don't want to load all objects from the database you might want to use the <tt>article_id</tt> directly:
-    #
-    #     articles_comments_url(@comment.article_id, @comment)
-    #
-    # * <tt>:name_prefix</tt> - Define a prefix for all generated routes, usually ending in an underscore.
-    #   Use this if you have named routes that may clash.
-    #
-    #     map.resources :tags, :path_prefix => '/books/:book_id', :name_prefix => 'book_'
-    #     map.resources :tags, :path_prefix => '/toys/:toy_id',   :name_prefix => 'toy_'
-    #
-    # You may also use <tt>:name_prefix</tt> to override the generic named routes in a nested \resource:
-    #
-    #   map.resources :articles do |article|
-    #     article.resources :comments, :name_prefix => nil
-    #   end
-    #
-    # This will yield named \resources like so:
-    #
-    #   comments_url(@article)
-    #   comment_url(@article, @comment)
-    #
-    # * <tt>:shallow</tt> - If true, paths for nested resources which reference a specific member
-    #   (ie. those with an :id parameter) will not use the parent path prefix or name prefix.
-    #
-    # The <tt>:shallow</tt> option is inherited by any nested resource(s).
-    #
-    # For example, 'users', 'posts' and 'comments' all use shallow paths with the following nested resources:
-    #
-    #   map.resources :users, :shallow => true do |user|
-    #     user.resources :posts do |post|
-    #       post.resources :comments
-    #     end
-    #   end
-    #   # --> GET /users/1/posts (maps to the PostsController#index action as usual)
-    #   #     also adds the usual named route called "user_posts"
-    #   # --> GET /posts/2 (maps to the PostsController#show action as if it were not nested)
-    #   #     also adds the named route called "post"
-    #   # --> GET /posts/2/comments (maps to the CommentsController#index action)
-    #   #     also adds the named route called "post_comments"
-    #   # --> GET /comments/2 (maps to the CommentsController#show action as if it were not nested)
-    #   #     also adds the named route called "comment"
-    #
-    # You may also use <tt>:shallow</tt> in combination with the +has_one+ and +has_many+ shorthand notations like:
-    #
-    #   map.resources :users, :has_many => { :posts => :comments }, :shallow => true
-    #
-    # * <tt>:only</tt> and <tt>:except</tt> - Specify which of the seven default actions should be routed to.
-    #
-    # <tt>:only</tt> and <tt>:except</tt> may be set to <tt>:all</tt>, <tt>:none</tt>, an action name or a
-    # list of action names. By default, routes are generated for all seven actions.
-    #
-    # For example:
-    #
-    #   map.resources :posts, :only => [:index, :show] do |post|
-    #     post.resources :comments, :except => [:update, :destroy]
-    #   end
-    #   # --> GET /posts (maps to the PostsController#index action)
-    #   # --> POST /posts (fails)
-    #   # --> GET /posts/1 (maps to the PostsController#show action)
-    #   # --> DELETE /posts/1 (fails)
-    #   # --> POST /posts/1/comments (maps to the CommentsController#create action)
-    #   # --> PUT /posts/1/comments/1 (fails)
-    #
-    # The <tt>:only</tt> and <tt>:except</tt> options are inherited by any nested resource(s).
-    #
-    # If <tt>map.resources</tt> is called with multiple resources, they all get the same options applied.
-    #
-    # Examples:
-    #
-    #   map.resources :messages, :path_prefix => "/thread/:thread_id"
-    #   # --> GET /thread/7/messages/1
-    #
-    #   map.resources :messages, :collection => { :rss => :get }
-    #   # --> GET /messages/rss (maps to the #rss action)
-    #   #     also adds a named route called "rss_messages"
-    #
-    #   map.resources :messages, :member => { :mark => :post }
-    #   # --> POST /messages/1/mark (maps to the #mark action)
-    #   #     also adds a named route called "mark_message"
-    #
-    #   map.resources :messages, :new => { :preview => :post }
-    #   # --> POST /messages/new/preview (maps to the #preview action)
-    #   #     also adds a named route called "preview_new_message"
-    #
-    #   map.resources :messages, :new => { :new => :any, :preview => :post }
-    #   # --> POST /messages/new/preview (maps to the #preview action)
-    #   #     also adds a named route called "preview_new_message"
-    #   # --> /messages/new can be invoked via any request method
-    #
-    #   map.resources :messages, :controller => "categories",
-    #         :path_prefix => "/category/:category_id",
-    #         :name_prefix => "category_"
-    #   # --> GET /categories/7/messages/1
-    #   #     has named route "category_message"
-    #
-    # The +resources+ method sets HTTP method restrictions on the routes it generates. For example, making an
-    # HTTP POST on <tt>new_message_url</tt> will raise a RoutingError exception. The default route in
-    # <tt>config/routes.rb</tt> overrides this and allows invalid HTTP methods for \resource routes.
-    def resources(*entities, &block)
-      options = entities.extract_options!
-      entities.each { |entity| map_resource(entity, options.dup, &block) }
-    end
-
-    # Creates named routes for implementing verb-oriented controllers for a singleton \resource.
-    # A singleton \resource is global to its current context.  For unnested singleton \resources,
-    # the \resource is global to the current user visiting the application, such as a user's
-    # <tt>/account</tt> profile.  For nested singleton \resources, the \resource is global to its parent
-    # \resource, such as a <tt>projects</tt> \resource that <tt>has_one :project_manager</tt>.
-    # The <tt>project_manager</tt> should be mapped as a singleton \resource under <tt>projects</tt>:
-    #
-    #   map.resources :projects do |project|
-    #     project.resource :project_manager
-    #   end
-    #
-    # See +resources+ for general conventions.  These are the main differences:
-    # * A singular name is given to <tt>map.resource</tt>.  The default controller name is still taken from the plural name.
-    # * To specify a custom plural name, use the <tt>:plural</tt> option.  There is no <tt>:singular</tt> option.
-    # * No default index route is created for the singleton \resource controller.
-    # * When nesting singleton \resources, only the singular name is used as the path prefix (example: 'account/messages/1')
-    #
-    # For example:
-    #
-    #   map.resource :account
-    #
-    # maps these actions in the Accounts controller:
-    #
-    #   class AccountsController < ActionController::Base
-    #     # GET new_account_url
-    #     def new
-    #       # return an HTML form for describing the new account
-    #     end
-    #
-    #     # POST account_url
-    #     def create
-    #       # create an account
-    #     end
-    #
-    #     # GET account_url
-    #     def show
-    #       # find and return the account
-    #     end
-    #
-    #     # GET edit_account_url
-    #     def edit
-    #       # return an HTML form for editing the account
-    #     end
-    #
-    #     # PUT account_url
-    #     def update
-    #       # find and update the account
-    #     end
-    #
-    #     # DELETE account_url
-    #     def destroy
-    #       # delete the account
-    #     end

-module ActionController # :nodoc:
-  # Represents an HTTP response generated by a controller action. One can use
-  # an ActionController::Response object to retrieve the current state
-  # of the response, or customize the response. An Response object can
-  # either represent a "real" HTTP response (i.e. one that is meant to be sent
-  # back to the web browser) or a test response (i.e. one that is generated
-  # from integration tests). See CgiResponse and TestResponse, respectively.
-  #
-  # Response is mostly a Ruby on Rails framework implement detail, and
-  # should never be used directly in controllers. Controllers should use the
-  # methods defined in ActionController::Base instead. For example, if you want
-  # to set the HTTP response's content MIME type, then use
-  # ActionControllerBase#headers instead of Response#headers.
-  #
-  # Nevertheless, integration tests may want to inspect controller responses in
-  # more detail, and that's when Response can be useful for application
-  # developers. Integration test methods such as
-  # ActionController::Integration::Session#get and
-  # ActionController::Integration::Session#post return objects of type
-  # TestResponse (which are of course also of type Response).
-  #
-  # For example, the following demo integration "test" prints the body of the
-  # controller response to the console:
-  #
-  #  class DemoControllerTest < ActionController::IntegrationTest
-  #    def test_print_root_path_to_console

+module ActionController
+  # Polymorphic URL helpers are methods for smart resolution to a named route call when
+  # given an Active Record model instance. They are to be used in combination with
+  # ActionController::Resources.
+  #
+  # These methods are useful when you want to generate correct URL or path to a RESTful
+  # resource without having to know the exact type of the record in question.
+  #
+  # Nested resources and/or namespaces are also supported, as illustrated in the example:
+  #
+  #   polymorphic_url([:admin, @article, @comment])
+  #
+  # results in:
+  #   
+  #   admin_article_comment_url(@article, @comment)
+  #
+  # == Usage within the framework
+  #
+  # Polymorphic URL helpers are used in a number of places throughout the Rails framework:
+  #
+  # * <tt>url_for</tt>, so you can use it with a record as the argument, e.g.
+  #   <tt>url_for(@article)</tt>;
+  # * ActionView::Helpers::FormHelper uses <tt>polymorphic_path</tt>, so you can write
+  #   <tt>form_for(@article)</tt> without having to specify <tt>:url</tt> parameter for the form
+  #   action;
+  # * <tt>redirect_to</tt> (which, in fact, uses <tt>url_for</tt>) so you can write
+  #   <tt>redirect_to(post)</tt> in your controllers;
+  # * ActionView::Helpers::AtomFeedHelper, so you don't have to explicitly specify URLs
+  #   for feed entries.
+  #
+  # == Prefixed polymorphic helpers
+  #
+  # In addition to <tt>polymorphic_url</tt> and <tt>polymorphic_path</tt> methods, a
+  # number of prefixed helpers are available as a shorthand to <tt>:action => "..."</tt>
+  # in options. Those are:
+  #
+  # * <tt>edit_polymorphic_url</tt>, <tt>edit_polymorphic_path</tt>
+  # * <tt>new_polymorphic_url</tt>, <tt>new_polymorphic_path</tt>
+  #
+  # Example usage:
+  #
+  #   edit_polymorphic_path(@post)              # => "/posts/1/edit"
+  #   polymorphic_path(@post, :format => :pdf)  # => "/posts/1.pdf"
+  module PolymorphicRoutes
+    # Constructs a call to a named RESTful route for the given record and returns the
+    # resulting URL string. For example:
+    #
+    #   # calls post_url(post)
+    #   polymorphic_url(post) # => "http://example.com/posts/1"
+    #   polymorphic_url([blog, post]) # => "http://example.com/blogs/1/posts/1"
+    #   polymorphic_url([:admin, blog, post]) # => "http://example.com/admin/blogs/1/posts/1"
+    #   polymorphic_url([user, :blog, post]) # => "http://example.com/users/1/blog/posts/1"
+    #
+    # ==== Options
+    #
+    # * <tt>:action</tt> - Specifies the action prefix for the named route:
+    #   <tt>:new</tt> or <tt>:edit</tt>. Default is no prefix.
+    # * <tt>:routing_type</tt> - Allowed values are <tt>:path</tt> or <tt>:url</tt>.

+module ActionController
+  # In <b>routes.rb</b> one defines URL-to-controller mappings, but the reverse
+  # is also possible: an URL can be generated from one of your routing definitions.
+  # URL generation functionality is centralized in this module.
+  #
+  # See ActionController::Routing and ActionController::Resources for general
+  # information about routing and routes.rb.
+  #
+  # <b>Tip:</b> If you need to generate URLs from your models or some other place,
+  # then ActionController::UrlWriter is what you're looking for. Read on for
+  # an introduction.
+  #
+  # == URL generation from parameters
+  #
+  # As you may know, some functions - such as ActionController::Base#url_for
+  # and ActionView::Helpers::UrlHelper#link_to, can generate URLs given a set
+  # of parameters. For example, you've probably had the chance to write code
+  # like this in one of your views:
+  #
+  #   <%= link_to('Click here', :controller => 'users',
+  #           :action => 'new', :message => 'Welcome!') %>
+  #
+  #   #=> Generates a link to: /users/new?message=Welcome%21
+  #
+  # link_to, and all other functions that require URL generation functionality,
+  # actually use ActionController::UrlWriter under the hood. And in particular,
+  # they use the ActionController::UrlWriter#url_for method. One can generate
+  # the same path as the above example by using the following code:
+  #
+  #   include UrlWriter
+  #   url_for(:controller => 'users',
+  #           :action => 'new',
+  #           :message => 'Welcome!',
+  #           :only_path => true)
+  #   # => "/users/new?message=Welcome%21"
+  #
+  # Notice the <tt>:only_path => true</tt> part. This is because UrlWriter has no
+  # information about the website hostname that your Rails app is serving. So if you
+  # want to include the hostname as well, then you must also pass the <tt>:host</tt>
+  # argument:
+  #
+  #   include UrlWriter
+  #   url_for(:controller => 'users',
+  #           :action => 'new',
+  #           :message => 'Welcome!',
+  #           :host => 'www.example.com')        # Changed this.
+  #   # => "http://www.example.com/users/new?message=Welcome%21"
+  #
+  # By default, all controllers and views have access to a special version of url_for,
+  # that already knows what the current hostname is. So if you use url_for in your
+  # controllers or your views, then you don't need to explicitly pass the <tt>:host</tt>
+  # argument.
+  #
+  # For convenience reasons, mailers provide a shortcut for ActionController::UrlWriter#url_for.
+  # So within mailers, you only have to type 'url_for' instead of 'ActionController::UrlWriter#url_for'
+  # in full. However, mailers don't have hostname information, and what's why you'll still
+  # have to specify the <tt>:host</tt> argument when generating URLs in mailers.
+  #
+  #
+  # == URL generation for named routes
+  #
+  # UrlWriter also allows one to access methods that have been auto-generated from
+  # named routes. For example, suppose that you have a 'users' resource in your
+  # <b>routes.rb</b>:
+  #
+  #   map.resources :users
+  #
+  # This generates, among other things, the method <tt>users_path</tt>. By default,
+  # this method is accessible from your controllers, views and mailers. If you need
+  # to access this auto-generated method from other places (such as a model), then
+  # you can do that in two ways.
+  #
+  # The first way is to include ActionController::UrlWriter in your class:
+  #
+  #   class User < ActiveRecord::Base
+  #     include ActionController::UrlWriter         # !!!
+  #
+  #     def name=(value)
+  #       write_attribute('name', value)
+  #       write_attribute('base_uri', users_path)   # !!!
+  #     end
+  #   end
+  #
+  # The second way is to access them through ActionController::UrlWriter.
+  # The autogenerated named routes methods are available as class methods:
+  #
+  #   class User < ActiveRecord::Base
+  #     def name=(value)
+  #       write_attribute('name', value)
+  #       path = ActionController::UrlWriter.users_path   # !!!
+  #       write_attribute('base_uri', path)               # !!!
+  #     end
+  #   end
+  module UrlWriter
+    # The default options for urls written by this writer. Typically a <tt>:host</tt>
+    # pair is provided.
+    mattr_accessor :default_url_options
+    self.default_url_options = {}
+
+    def self.included(base) #:nodoc:
+      ActionController::Routing::Routes.install_helpers(base)
+      base.mattr_accessor :default_url_options
+      base.default_url_options ||= default_url_options
+    end
+
+    # Generate a url based on the options provided, default_url_options and the
+    # routes defined in routes.rb.  The following options are supported:
+    #
+    # * <tt>:only_path</tt> - If true, the relative url is returned. Defaults to +false+.
+    # * <tt>:protocol</tt> - The protocol to connect to. Defaults to 'http'.
+    # * <tt>:host</tt> - Specifies the host the link should be targetted at.
+    #   If <tt>:only_path</tt> is false, this option must be
+    #   provided either explicitly, or via +default_url_options+.
+    # * <tt>:port</tt> - Optionally specify the port to connect to.
+    # * <tt>:anchor</tt> - An anchor name to be appended to the path.
+    # * <tt>:skip_relative_url_root</tt> - If true, the url is not constructed using the
+    #   +relative_url_root+ set in ActionController::Base.relative_url_root.
+    # * <tt>:trailing_slash</tt> - If true, adds a trailing slash, as in "/archive/2009/"
+    #
+    # Any other key (<tt>:controller</tt>, <tt>:action</tt>, etc.) given to
+    # +url_for+ is forwarded to the Routes module.
+    #
+    # Examples:
+    #
+    #    url_for :controller => 'tasks', :action => 'testing', :host=>'somehost.org', :port=>'8080'    # => 'http://somehost.org:8080/tasks/testing'

+module ActionController
+  # == Overview
+  #
+  # ActionController::Resources are a way of defining RESTful \resources.  A RESTful \resource, in basic terms,
+  # is something that can be pointed at and it will respond with a representation of the data requested.
+  # In real terms this could mean a user with a browser requests an HTML page, or that a desktop application
+  # requests XML data.
+  #
+  # RESTful design is based on the assumption that there are four generic verbs that a user of an
+  # application can request from a \resource (the noun).
+  #
+  # \Resources can be requested using four basic HTTP verbs (GET, POST, PUT, DELETE), the method used
+  # denotes the type of action that should take place.
+  #
+  # === The Different Methods and their Usage
+  #
+  # * GET    - Requests for a \resource, no saving or editing of a \resource should occur in a GET request.
+  # * POST   - Creation of \resources.
+  # * PUT    - Editing of attributes on a \resource.
+  # * DELETE - Deletion of a \resource.
+  #
+  # === Examples
+  #
+  #   # A GET request on the Posts resource is asking for all Posts
+  #   GET /posts
+  #
+  #   # A GET request on a single Post resource is asking for that particular Post
+  #   GET /posts/1
+  #
+  #   # A POST request on the Posts resource is asking for a Post to be created with the supplied details
+  #   POST /posts # with => { :post => { :title => "My Whizzy New Post", :body => "I've got a brand new combine harvester" } }
+  #
+  #   # A PUT request on a single Post resource is asking for a Post to be updated
+  #   PUT /posts # with => { :id => 1, :post => { :title => "Changed Whizzy Title" } }
+  #
+  #   # A DELETE request on a single Post resource is asking for it to be deleted
+  #   DELETE /posts # with => { :id => 1 }
+  #
+  # By using the REST convention, users of our application can assume certain things about how the data
+  # is requested and how it is returned.  Rails simplifies the routing part of RESTful design by
+  # supplying you with methods to create them in your routes.rb file.

+    # Along with the routes themselves, +resources+ generates named routes for use in
+    # controllers and views. <tt>map.resources :messages</tt> produces the following named routes and helpers:
+    #
+    #   Named Route   Helpers
+    #   ============  =====================================================
+    #   messages      messages_url, hash_for_messages_url,
+    #                 messages_path, hash_for_messages_path
+    #
+    #   message       message_url(id), hash_for_message_url(id),
+    #                 message_path(id), hash_for_message_path(id)
+    #
+    #   new_message   new_message_url, hash_for_new_message_url,
+    #                 new_message_path, hash_for_new_message_path
+    #
+    #   edit_message  edit_message_url(id), hash_for_edit_message_url(id),
+    #                 edit_message_path(id), hash_for_edit_message_path(id)
+    #
+    # You can use these helpers instead of +url_for+ or methods that take +url_for+ parameters. For example:
+    #
+    #   redirect_to :controller => 'messages', :action => 'index'
+    #   # and
+    #   <%= link_to "edit this message", :controller => 'messages', :action => 'edit', :id => @message.id %>
+    #
+    # now become:
+    #
+    #   redirect_to messages_url
+    #   # and
+    #   <%= link_to "edit this message", edit_message_url(@message) # calls @message.id automatically
+    #
+    # Since web browsers don't support the PUT and DELETE verbs, you will need to add a parameter '_method' to your
+    # form tags. The form helpers make this a little easier. For an update form with a <tt>@message</tt> object:
+    #
+    #   <%= form_tag message_path(@message), :method => :put %>
+    #
+    # or
+    #
+    #   <% form_for :message, @message, :url => message_path(@message), :html => {:method => :put} do |f| %>
+    #
+    # or
+    #
+    #   <% form_for @message do |f| %>
+    #
+    # which takes into account whether <tt>@message</tt> is a new record or not and generates the
+    # path and method accordingly.
+    #
+    # The +resources+ method accepts the following options to customize the resulting routes:
+    # * <tt>:collection</tt> - Add named routes for other actions that operate on the collection.
+    #   Takes a hash of <tt>#{action} => #{method}</tt>, where method is <tt>:get</tt>/<tt>:post</tt>/<tt>:put</tt>/<tt>:delete</tt>,
+    #   an array of any of the previous, or <tt>:any</tt> if the method does not matter.
+    #   These routes map to a URL like /messages/rss, with a route of +rss_messages_url+.
+    # * <tt>:member</tt> - Same as <tt>:collection</tt>, but for actions that operate on a specific member.
+    # * <tt>:new</tt> - Same as <tt>:collection</tt>, but for actions that operate on the new \resource action.
+    # * <tt>:controller</tt> - Specify the controller name for the routes.
+    # * <tt>:singular</tt> - Specify the singular name used in the member routes.
+    # * <tt>:requirements</tt> - Set custom routing parameter requirements; this is a hash of either 
+    #     regular expressions (which must match for the route to match) or extra parameters. For example:
+    #
+    #       map.resource :profile, :path_prefix => ':name', :requirements => { :name => /[a-zA-Z]+/, :extra => 'value' }
+    #
+    #     will only match if the first part is alphabetic, and will pass the parameter :extra to the controller.
+    # * <tt>:conditions</tt> - Specify custom routing recognition conditions.  \Resources sets the <tt>:method</tt> value for the method-specific routes.
+    # * <tt>:as</tt> - Specify a different \resource name to use in the URL path. For example:
+    #     # products_path == '/productos'
+    #     map.resources :products, :as => 'productos' do |product|
+    #       # product_reviews_path(product) == '/productos/1234/comentarios'
+    #       product.resources :product_reviews, :as => 'comentarios'
+    #     end
+    #
+    # * <tt>:has_one</tt> - Specify nested \resources, this is a shorthand for mapping singleton \resources beneath the current.
+    # * <tt>:has_many</tt> - Same has <tt>:has_one</tt>, but for plural \resources.
+    #
+    #   You may directly specify the routing association with +has_one+ and +has_many+ like:
+    #
+    #     map.resources :notes, :has_one => :author, :has_many => [:comments, :attachments]
+    #
+    #   This is the same as:
+    #
+    #     map.resources :notes do |notes|
+    #       notes.resource  :author
+    #       notes.resources :comments
+    #       notes.resources :attachments
+    #     end
+    #
+    # * <tt>:path_names</tt> - Specify different names for the 'new' and 'edit' actions. For example:
+    #     # new_products_path == '/productos/nuevo'
+    #     map.resources :products, :as => 'productos', :path_names => { :new => 'nuevo', :edit => 'editar' }
+    #
+    #   You can also set default action names from an environment, like this:
+    #     config.action_controller.resources_path_names = { :new => 'nuevo', :edit => 'editar' }
+    #
+    # * <tt>:path_prefix</tt> - Set a prefix to the routes with required route variables.
+    #
+    #   Weblog comments usually belong to a post, so you might use +resources+ like:
+    #
+    #     map.resources :articles
+    #     map.resources :comments, :path_prefix => '/articles/:article_id'
+    #
+    #   You can nest +resources+ calls to set this automatically:
+    #
+    #     map.resources :articles do |article|
+    #       article.resources :comments
+    #     end
+    #
+    #   The comment \resources work the same, but must now include a value for <tt>:article_id</tt>.
+    #
+    #     article_comments_url(@article)
+    #     article_comment_url(@article, @comment)
+    #
+    #     article_comments_url(:article_id => @article)
+    #     article_comment_url(:article_id => @article, :id => @comment)
+    #
+    #   If you don't want to load all objects from the database you might want to use the <tt>article_id</tt> directly:
+    #
+    #     articles_comments_url(@comment.article_id, @comment)
+    #
+    # * <tt>:name_prefix</tt> - Define a prefix for all generated routes, usually ending in an underscore.
+    #   Use this if you have named routes that may clash.
+    #
+    #     map.resources :tags, :path_prefix => '/books/:book_id', :name_prefix => 'book_'
+    #     map.resources :tags, :path_prefix => '/toys/:toy_id',   :name_prefix => 'toy_'
+    #
+    # You may also use <tt>:name_prefix</tt> to override the generic named routes in a nested \resource:
+    #
+    #   map.resources :articles do |article|
+    #     article.resources :comments, :name_prefix => nil
+    #   end
+    #
+    # This will yield named \resources like so:
+    #
+    #   comments_url(@article)
+    #   comment_url(@article, @comment)
+    #
+    # * <tt>:shallow</tt> - If true, paths for nested resources which reference a specific member
+    #   (ie. those with an :id parameter) will not use the parent path prefix or name prefix.
+    #
+    # The <tt>:shallow</tt> option is inherited by any nested resource(s).
+    #
+    # For example, 'users', 'posts' and 'comments' all use shallow paths with the following nested resources:
+    #
+    #   map.resources :users, :shallow => true do |user|
+    #     user.resources :posts do |post|
+    #       post.resources :comments
+    #     end
+    #   end
+    #   # --> GET /users/1/posts (maps to the PostsController#index action as usual)
+    #   #     also adds the usual named route called "user_posts"
+    #   # --> GET /posts/2 (maps to the PostsController#show action as if it were not nested)
+    #   #     also adds the named route called "post"
+    #   # --> GET /posts/2/comments (maps to the CommentsController#index action)
+    #   #     also adds the named route called "post_comments"
+    #   # --> GET /comments/2 (maps to the CommentsController#show action as if it were not nested)
+    #   #     also adds the named route called "comment"
+    #
+    # You may also use <tt>:shallow</tt> in combination with the +has_one+ and +has_many+ shorthand notations like:
+    #
+    #   map.resources :users, :has_many => { :posts => :comments }, :shallow => true
+    #
+    # * <tt>:only</tt> and <tt>:except</tt> - Specify which of the seven default actions should be routed to.
+    #
+    # <tt>:only</tt> and <tt>:except</tt> may be set to <tt>:all</tt>, <tt>:none</tt>, an action name or a
+    # list of action names. By default, routes are generated for all seven actions.
+    #
+    # For example:
+    #
+    #   map.resources :posts, :only => [:index, :show] do |post|
+    #     post.resources :comments, :except => [:update, :destroy]
+    #   end
+    #   # --> GET /posts (maps to the PostsController#index action)
+    #   # --> POST /posts (fails)
+    #   # --> GET /posts/1 (maps to the PostsController#show action)
+    #   # --> DELETE /posts/1 (fails)
+    #   # --> POST /posts/1/comments (maps to the CommentsController#create action)
+    #   # --> PUT /posts/1/comments/1 (fails)
+    #
+    # The <tt>:only</tt> and <tt>:except</tt> options are inherited by any nested resource(s).
+    #
+    # If <tt>map.resources</tt> is called with multiple resources, they all get the same options applied.
+    #
+    # Examples:
+    #
+    #   map.resources :messages, :path_prefix => "/thread/:thread_id"
+    #   # --> GET /thread/7/messages/1
+    #
+    #   map.resources :messages, :collection => { :rss => :get }
+    #   # --> GET /messages/rss (maps to the #rss action)
+    #   #     also adds a named route called "rss_messages"
+    #
+    #   map.resources :messages, :member => { :mark => :post }
+    #   # --> POST /messages/1/mark (maps to the #mark action)
+    #   #     also adds a named route called "mark_message"
+    #
+    #   map.resources :messages, :new => { :preview => :post }
+    #   # --> POST /messages/new/preview (maps to the #preview action)
+    #   #     also adds a named route called "preview_new_message"
+    #
+    #   map.resources :messages, :new => { :new => :any, :preview => :post }
+    #   # --> POST /messages/new/preview (maps to the #preview action)
+    #   #     also adds a named route called "preview_new_message"
+    #   # --> /messages/new can be invoked via any request method
+    #
+    #   map.resources :messages, :controller => "categories",
+    #         :path_prefix => "/category/:category_id",
+    #         :name_prefix => "category_"
+    #   # --> GET /categories/7/messages/1
+    #   #     has named route "category_message"
+    #
+    # The +resources+ method sets HTTP method restrictions on the routes it generates. For example, making an
+    # HTTP POST on <tt>new_message_url</tt> will raise a RoutingError exception. The default route in
+    # <tt>config/routes.rb</tt> overrides this and allows invalid HTTP methods for \resource routes.
+    def resources(*entities, &block)
+      options = entities.extract_options!
+      entities.each { |entity| map_resource(entity, options.dup, &block) }
+    end
+
+    # Creates named routes for implementing verb-oriented controllers for a singleton \resource.
+    # A singleton \resource is global to its current context.  For unnested singleton \resources,
+    # the \resource is global to the current user visiting the application, such as a user's
+    # <tt>/account</tt> profile.  For nested singleton \resources, the \resource is global to its parent
+    # \resource, such as a <tt>projects</tt> \resource that <tt>has_one :project_manager</tt>.
+    # The <tt>project_manager</tt> should be mapped as a singleton \resource under <tt>projects</tt>:
+    #
+    #   map.resources :projects do |project|
+    #     project.resource :project_manager
+    #   end
+    #
+    # See +resources+ for general conventions.  These are the main differences:
+    # * A singular name is given to <tt>map.resource</tt>.  The default controller name is still taken from the plural name.
+    # * To specify a custom plural name, use the <tt>:plural</tt> option.  There is no <tt>:singular</tt> option.
+    # * No default index route is created for the singleton \resource controller.
+    # * When nesting singleton \resources, only the singular name is used as the path prefix (example: 'account/messages/1')
+    #
+    # For example:
+    #
+    #   map.resource :account
+    #
+    # maps these actions in the Accounts controller:
+    #
+    #   class AccountsController < ActionController::Base
+    #     # GET new_account_url
+    #     def new
+    #       # return an HTML form for describing the new account
+    #     end
+    #
+    #     # POST account_url
+    #     def create
+    #       # create an account
+    #     end
+    #
+    #     # GET account_url
+    #     def show
+    #       # find and return the account
+    #     end
+    #
+    #     # GET edit_account_url
+    #     def edit
+    #       # return an HTML form for editing the account
+    #     end
+    #
+    #     # PUT account_url
+    #     def update
+    #       # find and update the account
+    #     end
+    #
+    #     # DELETE account_url

-require 'active_support/test_case'

-module ActionController
-  # Superclass for ActionController functional tests. Functional tests allow you to
-  # test a single controller action per test method. This should not be confused with
-  # integration tests (see ActionController::IntegrationTest), which are more like
-  # "stories" that can involve multiple controllers and mutliple actions (i.e. multiple
-  # different HTTP requests).
-  #
-  # == Basic example
-  #
-  # Functional tests are written as follows:
-  # 1. First, one uses the +get+, +post+, +put+, +delete+ or +head+ method to simulate
-  #    an HTTP request.
-  # 2. Then, one asserts whether the current state is as expected. "State" can be anything:
-  #    the controller's HTTP response, the database contents, etc.
-  #
-  # For example:
-  #
-  #   class BooksControllerTest < ActionController::TestCase
-  #     def test_create
-  #       # Simulate a POST response with the given HTTP parameters.
-  #       post(:create, :book => { :title => "Love Hina" })
-  #
-  #       # Assert that the controller tried to redirect us to
-  #       # the created book's URI.
-  #       assert_response :found
-  #
-  #       # Assert that the controller really put the book in the database.
-  #       assert_not_nil Book.find_by_title("Love Hina")
-  #     end
-  #   end
-  #
-  # == Special instance variables
-  #
-  # ActionController::TestCase will also automatically provide the following instance
-  # variables for use in the tests:
-  #
-  # <b>@controller</b>::
-  #      The controller instance that will be tested.
-  # <b>@request</b>::
-  #      An ActionController::TestRequest, representing the current HTTP
-  #      request. You can modify this object before sending the HTTP request. For example,
-  #      you might want to set some session properties before sending a GET request.
-  # <b>@response</b>::
-  #      An ActionController::TestResponse object, representing the response
-  #      of the last HTTP response. In the above example, <tt>@response</tt> becomes valid
-  #      after calling +post+. If the various assert methods are not sufficient, then you
-  #      may use this object to inspect the HTTP response in detail.
-  #
-  # (Earlier versions of Rails required each functional test to subclass
-  # Test::Unit::TestCase and define @controller, @request, @response in +setup+.)
-  #
-  # == Controller is automatically inferred
-  #
-  # ActionController::TestCase will automatically infer the controller under test
-  # from the test class name. If the controller cannot be inferred from the test
-  # class name, you can explicity set it with +tests+.
-  #
-  #   class SpecialEdgeCaseWidgetsControllerTest < ActionController::TestCase
-  #     tests WidgetController
-  #   end
-  #
-  # == Testing controller internals
-  #
-  # In addition to these specific assertions, you also have easy access to various collections that the regular test/unit assertions
-  # can be used against. These collections are:
-  #
-  # * assigns: Instance variables assigned in the action that are available for the view.
-  # * session: Objects being saved in the session.
-  # * flash: The flash objects currently in the session.
-  # * cookies: Cookies being sent to the user on this request.
-  #
-  # These collections can be used just like any other hash:
-  #
-  #   assert_not_nil assigns(:person) # makes sure that a @person instance variable was set
-  #   assert_equal "Dave", cookies[:name] # makes sure that a cookie called :name was set as "Dave"
-  #   assert flash.empty? # makes sure that there's nothing in the flash
-  #
-  # For historic reasons, the assigns hash uses string-based keys. So assigns[:person] won't work, but assigns["person"] will. To
-  # appease our yearning for symbols, though, an alternative accessor has been devised using a method call instead of index referencing.
-  # So assigns(:person) will work just like assigns["person"], but again, assigns[:person] will not work.
-  #
-  # On top of the collections, you have the complete url that a given action redirected to available in redirect_to_url.
-  #
-  # For redirects within the same controller, you can even call follow_redirect and the redirect will be followed, triggering another
-  # action call which can then be asserted against.
-  #
-  # == Manipulating the request collections
-  #
-  # The collections described above link to the response, so you can test if what the actions were expected to do happened. But
-  # sometimes you also want to manipulate these collections in the incoming request. This is really only relevant for sessions
-  # and cookies, though. For sessions, you just do:
-  #
-  #   @request.session[:key] = "value"
-  #   @request.cookies["key"] = "value"
-  #
-  # == Testing named routes
-  #
-  # If you're using named routes, they can be easily tested using the original named routes' methods straight in the test case.
-  # Example:
-  #
-  #  assert_redirected_to page_url(:title => 'foo')

+      # match +path+.  Basically, it asserts that Rails recognizes the route given by +expected_options+.
+      #
+      # Pass a hash in the second argument (+path+) to specify the request method.  This is useful for routes
+      # requiring a specific HTTP method.  The hash should contain a :path with the incoming request path

+      #
+      #
+      # ==== Example
+      # If the response contains two ordered lists, each with four list elements then:

+      #     assert_select "li", 8
+      #   end
+      #
+      # The selector may be a CSS selector expression (String), an expression
+      # with substitution values, or an HTML::Selector object.
+      #
+      # === Equality Tests
+      #
+      # The equality test may be one of the following:
+      # * <tt>true</tt> - Assertion is true if at least one element selected.
+      # * <tt>false</tt> - Assertion is true if no element selected.
+      # * <tt>String/Regexp</tt> - Assertion is true if the text value of at least
+      #   one element matches the string or regular expression.
+      # * <tt>Integer</tt> - Assertion is true if exactly that number of
+      #   elements are selected.

+      #
+      # Use the +id+ argument to narrow down the assertion to only statements
+      # that update or insert an element with that identifier.
+      #
+      # Use the first argument to narrow down assertions to only statements
+      # of that type. Possible values are <tt>:replace</tt>, <tt>:replace_html</tt>, 
+      # <tt>:show</tt>, <tt>:hide</tt>, <tt>:toggle</tt>, <tt>:remove</tt> and
+      # <tt>:insert_html</tt>.
+      #
+      # Use the argument <tt>:insert</tt> followed by an insertion position to narrow
+      # down the assertion to only statements that insert elements in that
+      # position. Possible values are <tt>:top</tt>, <tt>:bottom</tt>, <tt>:before</tt>
+      # and <tt>:after</tt>.
+      #
+      # Using the <tt>:remove</tt> statement, you will be able to pass a block, but it will
+      # be ignored as there is no HTML passed for this statement.
+      #
+      # === Using blocks
+      #
+      # Without a block, +assert_select_rjs+ merely asserts that the response
+      # contains one or more RJS statements that replace or update content.
+      #
+      # With a block, +assert_select_rjs+ also selects all elements used in
+      # these statements and passes them to the block. Nested assertions are
+      # supported.
+      #
+      # Calling +assert_select_rjs+ with no arguments and using nested asserts
+      # asserts that the HTML content is returned by one or more RJS statements.
+      # Using +assert_select+ directly makes the same assertion on the content,
+      # but without distinguishing whether the content is returned in an HTML
+      # or JavaScript.
+      #
+      # ==== Examples
+      #
+      #   # Replacing the element foo.
+      #   # page.replace 'foo', ...

+      #     than this number.
+      #   * <tt>:greater_than</tt>: the number of matching children must be
+      #     greater than this number.

+      #     to match on the children, and only matching children will be
+      #     counted.
+      # * <tt>:content</tt>: the textual content of the node must match the

+      #
+      # Conditions are matched using the following algorithm:

+module ActionController
+  # Superclass for ActionController functional tests. Functional tests allow you to
+  # test a single controller action per test method. This should not be confused with
+  # integration tests (see ActionController::IntegrationTest), which are more like
+  # "stories" that can involve multiple controllers and mutliple actions (i.e. multiple
+  # different HTTP requests).
+  #
+  # == Basic example
+  #
+  # Functional tests are written as follows:
+  # 1. First, one uses the +get+, +post+, +put+, +delete+ or +head+ method to simulate
+  #    an HTTP request.
+  # 2. Then, one asserts whether the current state is as expected. "State" can be anything:
+  #    the controller's HTTP response, the database contents, etc.
+  #
+  # For example:
+  #
+  #   class BooksControllerTest < ActionController::TestCase
+  #     def test_create
+  #       # Simulate a POST response with the given HTTP parameters.
+  #       post(:create, :book => { :title => "Love Hina" })
+  #
+  #       # Assert that the controller tried to redirect us to
+  #       # the created book's URI.
+  #       assert_response :found
+  #
+  #       # Assert that the controller really put the book in the database.
+  #       assert_not_nil Book.find_by_title("Love Hina")
+  #     end
+  #   end
+  #
+  # == Special instance variables
+  #
+  # ActionController::TestCase will also automatically provide the following instance
+  # variables for use in the tests:
+  #
+  # <b>@controller</b>::
+  #      The controller instance that will be tested.
+  # <b>@request</b>::
+  #      An ActionController::TestRequest, representing the current HTTP
+  #      request. You can modify this object before sending the HTTP request. For example,
+  #      you might want to set some session properties before sending a GET request.
+  # <b>@response</b>::
+  #      An ActionController::TestResponse object, representing the response
+  #      of the last HTTP response. In the above example, <tt>@response</tt> becomes valid
+  #      after calling +post+. If the various assert methods are not sufficient, then you
+  #      may use this object to inspect the HTTP response in detail.
+  #
+  # (Earlier versions of Rails required each functional test to subclass
+  # Test::Unit::TestCase and define @controller, @request, @response in +setup+.)
+  #
+  # == Controller is automatically inferred
+  #
+  # ActionController::TestCase will automatically infer the controller under test
+  # from the test class name. If the controller cannot be inferred from the test
+  # class name, you can explicity set it with +tests+.
+  #
+  #   class SpecialEdgeCaseWidgetsControllerTest < ActionController::TestCase
+  #     tests WidgetController
+  #   end
+  #
+  # == Testing controller internals
+  #
+  # In addition to these specific assertions, you also have easy access to various collections that the regular test/unit assertions
+  # can be used against. These collections are:
+  #
+  # * assigns: Instance variables assigned in the action that are available for the view.
+  # * session: Objects being saved in the session.
+  # * flash: The flash objects currently in the session.
+  # * cookies: Cookies being sent to the user on this request.
+  #
+  # These collections can be used just like any other hash:
+  #
+  #   assert_not_nil assigns(:person) # makes sure that a @person instance variable was set
+  #   assert_equal "Dave", cookies[:name] # makes sure that a cookie called :name was set as "Dave"
+  #   assert flash.empty? # makes sure that there's nothing in the flash
+  #
+  # For historic reasons, the assigns hash uses string-based keys. So assigns[:person] won't work, but assigns["person"] will. To
+  # appease our yearning for symbols, though, an alternative accessor has been devised using a method call instead of index referencing.
+  # So assigns(:person) will work just like assigns["person"], but again, assigns[:person] will not work.
+  #
+  # On top of the collections, you have the complete url that a given action redirected to available in redirect_to_url.
+  #
+  # For redirects within the same controller, you can even call follow_redirect and the redirect will be followed, triggering another
+  # action call which can then be asserted against.
+  #
+  # == Manipulating the request collections
+  #
+  # The collections described above link to the response, so you can test if what the actions were expected to do happened. But
+  # sometimes you also want to manipulate these collections in the incoming request. This is really only relevant for sessions
+  # and cookies, though. For sessions, you just do:
+  #
+  #   @request.session[:key] = "value"
+  #   @request.cookies["key"] = "value"
+  #
+  # == Testing named routes
+  #
+  # If you're using named routes, they can be easily tested using the original named routes' methods straight in the test case.
+  # Example:
+  #
+  #  assert_redirected_to page_url(:title => 'foo')

-module ActionController
-  # In <b>routes.rb</b> one defines URL-to-controller mappings, but the reverse
-  # is also possible: an URL can be generated from one of your routing definitions.
-  # URL generation functionality is centralized in this module.
-  #
-  # See ActionController::Routing and ActionController::Resources for general
-  # information about routing and routes.rb.
-  #
-  # <b>Tip:</b> If you need to generate URLs from your models or some other place,
-  # then ActionController::UrlWriter is what you're looking for. Read on for
-  # an introduction.
-  #
-  # == URL generation from parameters
-  #
-  # As you may know, some functions - such as ActionController::Base#url_for
-  # and ActionView::Helpers::UrlHelper#link_to, can generate URLs given a set
-  # of parameters. For example, you've probably had the chance to write code
-  # like this in one of your views:
-  #
-  #   <%= link_to('Click here', :controller => 'users',
-  #           :action => 'new', :message => 'Welcome!') %>
-  #
-  #   #=> Generates a link to: /users/new?message=Welcome%21
-  #
-  # link_to, and all other functions that require URL generation functionality,
-  # actually use ActionController::UrlWriter under the hood. And in particular,
-  # they use the ActionController::UrlWriter#url_for method. One can generate
-  # the same path as the above example by using the following code:
-  #
-  #   include UrlWriter
-  #   url_for(:controller => 'users',
-  #           :action => 'new',
-  #           :message => 'Welcome!',
-  #           :only_path => true)
-  #   # => "/users/new?message=Welcome%21"
-  #
-  # Notice the <tt>:only_path => true</tt> part. This is because UrlWriter has no
-  # information about the website hostname that your Rails app is serving. So if you
-  # want to include the hostname as well, then you must also pass the <tt>:host</tt>
-  # argument:
-  #
-  #   include UrlWriter
-  #   url_for(:controller => 'users',
-  #           :action => 'new',
-  #           :message => 'Welcome!',
-  #           :host => 'www.example.com')        # Changed this.
-  #   # => "http://www.example.com/users/new?message=Welcome%21"
-  #
-  # By default, all controllers and views have access to a special version of url_for,
-  # that already knows what the current hostname is. So if you use url_for in your
-  # controllers or your views, then you don't need to explicitly pass the <tt>:host</tt>
-  # argument.
-  #
-  # For convenience reasons, mailers provide a shortcut for ActionController::UrlWriter#url_for.
-  # So within mailers, you only have to type 'url_for' instead of 'ActionController::UrlWriter#url_for'
-  # in full. However, mailers don't have hostname information, and what's why you'll still
-  # have to specify the <tt>:host</tt> argument when generating URLs in mailers.
-  #
-  #
-  # == URL generation for named routes
-  #
-  # UrlWriter also allows one to access methods that have been auto-generated from
-  # named routes. For example, suppose that you have a 'users' resource in your
-  # <b>routes.rb</b>:
-  #
-  #   map.resources :users
-  #
-  # This generates, among other things, the method <tt>users_path</tt>. By default,
-  # this method is accessible from your controllers, views and mailers. If you need
-  # to access this auto-generated method from other places (such as a model), then
-  # you can do that in two ways.
-  #
-  # The first way is to include ActionController::UrlWriter in your class:
-  #
-  #   class User < ActiveRecord::Base
-  #     include ActionController::UrlWriter         # !!!
-  #
-  #     def name=(value)
-  #       write_attribute('name', value)
-  #       write_attribute('base_uri', users_path)   # !!!
-  #     end
-  #   end
-  #
-  # The second way is to access them through ActionController::UrlWriter.
-  # The autogenerated named routes methods are available as class methods:
-  #
-  #   class User < ActiveRecord::Base
-  #     def name=(value)
-  #       write_attribute('name', value)
-  #       path = ActionController::UrlWriter.users_path   # !!!
-  #       write_attribute('base_uri', path)               # !!!
-  #     end
-  #   end
-  module UrlWriter
-    # The default options for urls written by this writer. Typically a <tt>:host</tt>
-    # pair is provided.
-    mattr_accessor :default_url_options
-    self.default_url_options = {}
-
-    def self.included(base) #:nodoc:
-      ActionController::Routing::Routes.install_helpers(base)
-      base.mattr_accessor :default_url_options
-      base.default_url_options ||= default_url_options
-    end
-
-    # Generate a url based on the options provided, default_url_options and the
-    # routes defined in routes.rb.  The following options are supported:
-    #
-    # * <tt>:only_path</tt> - If true, the relative url is returned. Defaults to +false+.
-    # * <tt>:protocol</tt> - The protocol to connect to. Defaults to 'http'.
-    # * <tt>:host</tt> - Specifies the host the link should be targetted at.
-    #   If <tt>:only_path</tt> is false, this option must be
-    #   provided either explicitly, or via +default_url_options+.
-    # * <tt>:port</tt> - Optionally specify the port to connect to.
-    # * <tt>:anchor</tt> - An anchor name to be appended to the path.
-    # * <tt>:skip_relative_url_root</tt> - If true, the url is not constructed using the
-    #   +relative_url_root+ set in ActionController::Base.relative_url_root.
-    # * <tt>:trailing_slash</tt> - If true, adds a trailing slash, as in "/archive/2009/"
-    #
-    # Any other key (<tt>:controller</tt>, <tt>:action</tt>, etc.) given to
-    # +url_for+ is forwarded to the Routes module.
-    #
-    # Examples:
-    #
-    #    url_for :controller => 'tasks', :action => 'testing', :host=>'somehost.org', :port=>'8080'    # => 'http://somehost.org:8080/tasks/testing'

-
-    # This module provides a class-level method for specifying that certain
-    # actions are guarded against being called without certain prerequisites
-    # being met. This is essentially a special kind of before_filter.
-    #
-    # An action may be guarded against being invoked without certain request
-    # parameters being set, or without certain session values existing.
-    #
-    # When a verification is violated, values may be inserted into the flash, and
-    # a specified redirection is triggered. If no specific action is configured,
-    # verification failures will by default result in a 400 Bad Request response.
-    #
-    # Usage:
-    #
-    #   class GlobalController < ActionController::Base
-    #     # Prevent the #update_settings action from being invoked unless
-    #     # the 'admin_privileges' request parameter exists. The
-    #     # settings action will be redirected to in current controller
-    #     # if verification fails.
-    #     verify :params => "admin_privileges", :only => :update_post,
-    #            :redirect_to => { :action => "settings" }
-    #
-    #     # Disallow a post from being updated if there was no information
-    #     # submitted with the post, and if there is no active post in the
-    #     # session, and if there is no "note" key in the flash. The route
-    #     # named category_url will be redirected to if verification fails.
-    #
-    #     verify :params => "post", :session => "post", "flash" => "note",
-    #            :only => :update_post,
-    #            :add_flash => { "alert" => "Failed to create your message" },
-    #            :redirect_to => :category_url
-    #
-    # Note that these prerequisites are not business rules. They do not examine 
-    # the content of the session or the parameters. That level of validation should
-    # be encapsulated by your domain model or helper methods in the controller.
-    module ClassMethods
-      # Verify the given actions so that if certain prerequisites are not met,
-      # the user is redirected to a different action. The +options+ parameter
-      # is a hash consisting of the following key/value pairs:
-      #
-      # <tt>:params</tt>:: 
-      #   a single key or an array of keys that must be in the <tt>params</tt> 
-      #   hash in order for the action(s) to be safely called.
-      # <tt>:session</tt>:: 
-      #   a single key or an array of keys that must be in the <tt>session</tt> 
-      #   in order for the action(s) to be safely called.
-      # <tt>:flash</tt>:: 
-      #   a single key or an array of keys that must be in the flash in order 
-      #   for the action(s) to be safely called.
-      # <tt>:method</tt>:: 
-      #   a single key or an array of keys--any one of which must match the 
-      #   current request method in order for the action(s) to be safely called. 
-      #   (The key should be a symbol: <tt>:get</tt> or <tt>:post</tt>, for 
-      #   example.)
-      # <tt>:xhr</tt>:: 
-      #   true/false option to ensure that the request is coming from an Ajax 
-      #   call or not. 
-      # <tt>:add_flash</tt>:: 
-      #   a hash of name/value pairs that should be merged into the session's 
-      #   flash if the prerequisites cannot be satisfied.
-      # <tt>:add_headers</tt>:: 
-      #   a hash of name/value pairs that should be merged into the response's 
-      #   headers hash if the prerequisites cannot be satisfied.
-      # <tt>:redirect_to</tt>:: 
-      #   the redirection parameters to be used when redirecting if the 
-      #   prerequisites cannot be satisfied. You can redirect either to named 
-      #   route or to the action in some controller.

-module ActionController # :nodoc:
-  # Represents an HTTP response generated by a controller action. One can use
-  # an ActionController::Response object to retrieve the current state
-  # of the response, or customize the response. An Response object can
-  # either represent a "real" HTTP response (i.e. one that is meant to be sent
-  # back to the web browser) or a test response (i.e. one that is generated
-  # from integration tests). See CgiResponse and TestResponse, respectively.
-  #
-  # Response is mostly a Ruby on Rails framework implement detail, and
-  # should never be used directly in controllers. Controllers should use the
-  # methods defined in ActionController::Base instead. For example, if you want
-  # to set the HTTP response's content MIME type, then use
-  # ActionControllerBase#headers instead of Response#headers.
-  #
-  # Nevertheless, integration tests may want to inspect controller responses in
-  # more detail, and that's when Response can be useful for application
-  # developers. Integration test methods such as
-  # ActionController::Integration::Session#get and
-  # ActionController::Integration::Session#post return objects of type
-  # TestResponse (which are of course also of type Response).
-  #
-  # For example, the following demo integration "test" prints the body of the
-  # controller response to the console:
-  #
-  #  class DemoControllerTest < ActionController::IntegrationTest
-  #    def test_print_root_path_to_console
-  #      get('/')
-  #      puts @response.body

-module ActionController
-  module Session
-    # This cookie-based session store is the Rails default. Sessions typically
-    # contain at most a user_id and flash message; both fit within the 4K cookie
-    # size limit. Cookie-based sessions are dramatically faster than the
-    # alternatives.
-    #
-    # If you have more than 4K of session data or don't want your data to be
-    # visible to the user, pick another session store.
-    #
-    # CookieOverflow is raised if you attempt to store more than 4K of data.
-    #
-    # A message digest is included with the cookie to ensure data integrity:
-    # a user cannot alter his +user_id+ without knowing the secret key
-    # included in the hash. New apps are generated with a pregenerated secret
-    # in config/environment.rb. Set your own for old apps you're upgrading.
-    #
-    # Session options:
-    #
-    # * <tt>:secret</tt>: An application-wide key string or block returning a
-    #   string called per generated digest. The block is called with the
-    #   CGI::Session instance as an argument. It's important that the secret
-    #   is not vulnerable to a dictionary attack. Therefore, you should choose
-    #   a secret consisting of random numbers and letters and more than 30
-    #   characters. Examples:
-    #
-    #     :secret => '449fe2e7daee471bffae2fd8dc02313d'
-    #     :secret => Proc.new { User.current_user.secret_key }
-    #
-    # * <tt>:digest</tt>: The message digest algorithm used to verify session
-    #   integrity defaults to 'SHA1' but may be any digest provided by OpenSSL,
-    #   such as 'MD5', 'RIPEMD160', 'SHA256', etc.
-    #
-    # To generate a secret key for an existing application, run
-    # "rake secret" and set the key in config/environment.rb.

+module ActionDispatch # :nodoc:
+  # Represents an HTTP response generated by a controller action. One can use
+  # an ActionController::Response object to retrieve the current state
+  # of the response, or customize the response. An Response object can
+  # either represent a "real" HTTP response (i.e. one that is meant to be sent
+  # back to the web browser) or a test response (i.e. one that is generated
+  # from integration tests). See CgiResponse and TestResponse, respectively.
+  #
+  # Response is mostly a Ruby on Rails framework implement detail, and
+  # should never be used directly in controllers. Controllers should use the
+  # methods defined in ActionController::Base instead. For example, if you want
+  # to set the HTTP response's content MIME type, then use
+  # ActionControllerBase#headers instead of Response#headers.
+  #
+  # Nevertheless, integration tests may want to inspect controller responses in
+  # more detail, and that's when Response can be useful for application
+  # developers. Integration test methods such as
+  # ActionController::Integration::Session#get and
+  # ActionController::Integration::Session#post return objects of type
+  # TestResponse (which are of course also of type Response).
+  #
+  # For example, the following demo integration "test" prints the body of the
+  # controller response to the console:
+  #
+  #  class DemoControllerTest < ActionController::IntegrationTest
+  #    def test_print_root_path_to_console
+  #      get('/')

+    #   a secret consisting of random numbers and letters and more than 30
+    #   characters. Examples:

+    #     :secret => '449fe2e7daee471bffae2fd8dc02313d'

-    # Rack::Auth::OpenID provides a simple method for setting up an OpenID
-    # Consumer. It requires the ruby-openid library from janrain to operate,
-    # as well as a rack method of session management.
-    #
-    # The ruby-openid home page is at http://openidenabled.com/ruby-openid/.
-    #
-    # The OpenID specifications can be found at
-    # http://openid.net/specs/openid-authentication-1_1.html
-    # and
-    # http://openid.net/specs/openid-authentication-2_0.html. Documentation
-    # for published OpenID extensions and related topics can be found at
-    # http://openid.net/developers/specs/.
-    #
-    # It is recommended to read through the OpenID spec, as well as
-    # ruby-openid's documentation, to understand what exactly goes on. However
-    # a setup as simple as the presented examples is enough to provide
-    # Consumer functionality.
-    #
-    # This library strongly intends to utilize the OpenID 2.0 features of the
-    # ruby-openid library, which provides OpenID 1.0 compatiblity.
-    #
-    # NOTE: Due to the amount of data that this library stores in the
-    # session, Rack::Session::Cookie may fault.
-

-
-      class NoSession < RuntimeError; end
-      class BadExtension < RuntimeError; end
-      # Required for ruby-openid
-      ValidStatus = [:success, :setup_needed, :cancel, :failure]
-
-      # = Arguments
-      #
-      # The first argument is the realm, identifying the site they are trusting
-      # with their identity. This is required, also treated as the trust_root
-      # in OpenID 1.x exchanges.
-      #
-      # The optional second argument is a hash of options.
-      #
-      # == Options
-      #
-      # <tt>:return_to</tt> defines the url to return to after the client
-      # authenticates with the openid service provider. This url should point
-      # to where Rack::Auth::OpenID is mounted. If <tt>:return_to</tt> is not
-      # provided, return_to will be the current url which allows flexibility
-      # with caveats.
-      #
-      # <tt>:session_key</tt> defines the key to the session hash in the env.
-      # It defaults to 'rack.session'.
-      #
-      # <tt>:openid_param</tt> defines at what key in the request parameters to
-      # find the identifier to resolve. As per the 2.0 spec, the default is
-      # 'openid_identifier'.
-      #
-      # <tt>:store</tt> defined what OpenID Store to use for persistant
-      # information. By default a Store::Memory will be used.
-      #
-      # <tt>:immediate</tt> as true will make initial requests to be of an
-      # immediate type. This is false by default. See OpenID specification
-      # documentation.
-      #
-      # <tt>:extensions</tt> should be a hash of openid extension
-      # implementations. The key should be the extension main module, the value
-      # should be an array of arguments for extension::Request.new.
-      # The hash is iterated over and passed to #add_extension for processing.
-      # Please see #add_extension for further documentation.
-      #
-      # == Examples
-      #
-      #   simple_oid = OpenID.new('http://mysite.com/')
-      #
-      #   return_oid = OpenID.new('http://mysite.com/', {
-      #     :return_to => 'http://mysite.com/openid'
-      #   })
-      #
-      #   complex_oid = OpenID.new('http://mysite.com/',
-      #     :immediate => true,
-      #     :extensions => {
-      #       ::OpenID::SReg => [['email'],['nickname']]
-      #     }
-      #   )
-      #
-      # = Advanced
-      #
-      # Most of the functionality of this library is encapsulated such that
-      # expansion and overriding functions isn't difficult nor tricky.
-      # Alternately, to avoid opening up singleton objects or subclassing, a
-      # wrapper rack middleware can be composed to act upon Auth::OpenID's
-      # responses. See #check and #finish for locations of pertinent data.
-      #
-      # == Responses
-      #
-      # To change the responses that Auth::OpenID returns, override the methods
-      # #redirect, #bad_request, #unauthorized, #access_denied, and
-      # #foreign_server_failure.
-      #
-      # Additionally #confirm_post_params is used when the URI would exceed
-      # length limits on a GET request when doing the initial verification
-      # request.
-      #
-      # == Processing
-      #
-      # To change methods of processing completed transactions, override the
-      # methods #success, #setup_needed, #cancel, and #failure. Please ensure
-      # the returned object is a rack compatible response.
-      #
-      # The first argument is an OpenID::Response, the second is a
-      # Rack::Request of the current request, the last is the hash used in
-      # ruby-openid handling, which can be found manually at
-      # env['rack.session'][:openid].
-      #

-      # setting up user accounts.

-
-      ## <tt>REQUEST_METHOD</tt>:: The HTTP request method, such as
-      ##                           "GET" or "POST". This cannot ever
-      ##                           be an empty string, and so is
-      ##                           always required.
-
-      ## <tt>SCRIPT_NAME</tt>:: The initial portion of the request
-      ##                        URL's "path" that corresponds to the
-      ##                        application object, so that the

-      ##                        "location". This may be an empty
-      ##                        string, if the application corresponds
-      ##                        to the "root" of the server.
-
-      ## <tt>PATH_INFO</tt>:: The remainder of the request URL's
-      ##                      "path", designating the virtual
-      ##                      "location" of the request's target
-      ##                      within the application. This may be an
-      ##                      empty string, if the request URL targets
-      ##                      the application root and does not have a
-      ##                      trailing slash. This information should be
-      ##                      decoded by the server if it comes from a
-      ##                      URL.
-
-      ## <tt>QUERY_STRING</tt>:: The portion of the request URL that
-      ##                         follows the <tt>?</tt>, if any. May be
-      ##                         empty, but is always required!
-
-      ## <tt>SERVER_NAME</tt>, <tt>SERVER_PORT</tt>:: When combined with <tt>SCRIPT_NAME</tt> and <tt>PATH_INFO</tt>, these variables can be used to complete the URL. Note, however, that <tt>HTTP_HOST</tt>, if present, should be used in preference to <tt>SERVER_NAME</tt> for reconstructing the request URL.  <tt>SERVER_NAME</tt> and <tt>SERVER_PORT</tt> can never be empty strings, and so are always required.
-
-      ## <tt>HTTP_</tt> Variables:: Variables corresponding to the
-      ##                            client-supplied HTTP request
-      ##                            headers (i.e., variables whose
-      ##                            names begin with <tt>HTTP_</tt>). The

+    # as well as a rack method of session management.
+    #
+    # The ruby-openid home page is at http://openidenabled.com/ruby-openid/.
+    #
+    # The OpenID specifications can be found at
+    # http://openid.net/specs/openid-authentication-1_1.html
+    # and
+    # http://openid.net/specs/openid-authentication-2_0.html. Documentation
+    # for published OpenID extensions and related topics can be found at
+    # http://openid.net/developers/specs/.
+    #
+    # It is recommended to read through the OpenID spec, as well as
+    # ruby-openid's documentation, to understand what exactly goes on. However
+    # a setup as simple as the presented examples is enough to provide
+    # Consumer functionality.
+    #
+    # This library strongly intends to utilize the OpenID 2.0 features of the
+    # ruby-openid library, which provides OpenID 1.0 compatiblity.
+    #
+    # NOTE: Due to the amount of data that this library stores in the

+      # Required for ruby-openid
+      ValidStatus = [:success, :setup_needed, :cancel, :failure]
+
+      # = Arguments
+      #
+      # The first argument is the realm, identifying the site they are trusting
+      # with their identity. This is required, also treated as the trust_root
+      # in OpenID 1.x exchanges.
+      #
+      # The optional second argument is a hash of options.
+      #
+      # == Options
+      #
+      # <tt>:return_to</tt> defines the url to return to after the client
+      # authenticates with the openid service provider. This url should point
+      # to where Rack::Auth::OpenID is mounted. If <tt>:return_to</tt> is not
+      # provided, return_to will be the current url which allows flexibility
+      # with caveats.
+      #
+      # <tt>:session_key</tt> defines the key to the session hash in the env.
+      # It defaults to 'rack.session'.
+      #
+      # <tt>:openid_param</tt> defines at what key in the request parameters to
+      # find the identifier to resolve. As per the 2.0 spec, the default is
+      # 'openid_identifier'.
+      #
+      # <tt>:store</tt> defined what OpenID Store to use for persistant
+      # information. By default a Store::Memory will be used.
+      #
+      # <tt>:immediate</tt> as true will make initial requests to be of an
+      # immediate type. This is false by default. See OpenID specification
+      # documentation.
+      #
+      # <tt>:extensions</tt> should be a hash of openid extension
+      # implementations. The key should be the extension main module, the value
+      # should be an array of arguments for extension::Request.new.
+      # The hash is iterated over and passed to #add_extension for processing.
+      # Please see #add_extension for further documentation.
+      #
+      # == Examples
+      #
+      #   simple_oid = OpenID.new('http://mysite.com/')
+      #
+      #   return_oid = OpenID.new('http://mysite.com/', {
+      #     :return_to => 'http://mysite.com/openid'
+      #   })
+      #
+      #   complex_oid = OpenID.new('http://mysite.com/',
+      #     :immediate => true,
+      #     :extensions => {
+      #       ::OpenID::SReg => [['email'],['nickname']]
+      #     }
+      #   )
+      #
+      # = Advanced
+      #
+      # Most of the functionality of this library is encapsulated such that
+      # expansion and overriding functions isn't difficult nor tricky.
+      # Alternately, to avoid opening up singleton objects or subclassing, a
+      # wrapper rack middleware can be composed to act upon Auth::OpenID's
+      # responses. See #check and #finish for locations of pertinent data.
+      #
+      # == Responses
+      #
+      # To change the responses that Auth::OpenID returns, override the methods
+      # #redirect, #bad_request, #unauthorized, #access_denied, and
+      # #foreign_server_failure.
+      #
+      # Additionally #confirm_post_params is used when the URI would exceed
+      # length limits on a GET request when doing the initial verification
+      # request.
+      #
+      # == Processing
+      #
+      # To change methods of processing completed transactions, override the
+      # methods #success, #setup_needed, #cancel, and #failure. Please ensure
+      # the returned object is a rack compatible response.
+      #
+      # The first argument is an OpenID::Response, the second is a
+      # Rack::Request of the current request, the last is the hash used in
+      # ruby-openid handling, which can be found manually at
+      # env['rack.session'][:openid].
+      #

+      ##
+      ## The environment is required to include these variables
+      ## (adopted from PEP333), except when they'd be empty, but see
+      ## below.
+
+      ## <tt>REQUEST_METHOD</tt>:: The HTTP request method, such as
+      ##                           "GET" or "POST". This cannot ever
+      ##                           be an empty string, and so is
+      ##                           always required.
+
+      ## <tt>SCRIPT_NAME</tt>:: The initial portion of the request
+      ##                        URL's "path" that corresponds to the
+      ##                        application object, so that the
+      ##                        application knows its virtual
+      ##                        "location". This may be an empty
+      ##                        string, if the application corresponds
+      ##                        to the "root" of the server.
+
+      ## <tt>PATH_INFO</tt>:: The remainder of the request URL's
+      ##                      "path", designating the virtual
+      ##                      "location" of the request's target
+      ##                      within the application. This may be an
+      ##                      empty string, if the request URL targets
+      ##                      the application root and does not have a
+      ##                      trailing slash. This information should be
+      ##                      decoded by the server if it comes from a
+      ##                      URL.
+
+      ## <tt>QUERY_STRING</tt>:: The portion of the request URL that
+      ##                         follows the <tt>?</tt>, if any. May be
+      ##                         empty, but is always required!
+
+      ## <tt>SERVER_NAME</tt>, <tt>SERVER_PORT</tt>:: When combined with <tt>SCRIPT_NAME</tt> and <tt>PATH_INFO</tt>, these variables can be used to complete the URL. Note, however, that <tt>HTTP_HOST</tt>, if present, should be used in preference to <tt>SERVER_NAME</tt> for reconstructing the request URL.  <tt>SERVER_NAME</tt> and <tt>SERVER_PORT</tt> can never be empty strings, and so are always required.
+
+      ## <tt>HTTP_</tt> Variables:: Variables corresponding to the
+      ##                            client-supplied HTTP request
+      ##                            headers (i.e., variables whose
+      ##                            names begin with <tt>HTTP_</tt>). The
+      ##                            presence or absence of these
+      ##                            variables should correspond with
+      ##                            the presence or absence of the
+      ##                            appropriate HTTP header in the
+      ##                            request.
+
+      ## In addition to this, the Rack environment must include these
+      ## Rack-specific variables:
+
+      ## <tt>rack.version</tt>:: The Array [0,1], representing this version of Rack.
+      ## <tt>rack.url_scheme</tt>:: +http+ or +https+, depending on the request URL.
+      ## <tt>rack.input</tt>:: See below, the input stream.
+      ## <tt>rack.errors</tt>:: See below, the error stream.
+      ## <tt>rack.multithread</tt>:: true if the application object may be simultaneously invoked by another thread in the same process, false otherwise.
+      ## <tt>rack.multiprocess</tt>:: true if an equivalent application object may be simultaneously invoked by another process, false otherwise.
+      ## <tt>rack.run_once</tt>:: true if the server expects (but does not guarantee!) that the application will only be invoked this one time during the life of its containing process. Normally, this will only be true for a server based on CGI (or something similar).
+
+      ## The server or the application can store their own data in the
+      ## environment, too.  The keys must contain at least one dot,
+      ## and should be prefixed uniquely.  The prefix <tt>rack.</tt>
