module ActionController #:nodoc: # Cookies are read and written through ActionController#cookies. The cookies being read is what was received along with the request, # the cookies being written is what will be sent out will the response. Cookies are read by value (so you won't get the cookie object # itself back -- just the value it holds). Examples for writting: # # cookies["user_name"] = "david" # => Will set a simple session cookie # cookies["login"] = { :value => "XJ-122", :expires => Time.now + 360} # => Will set a cookie that expires in 1 hour # # Examples for reading: # # cookies["user_name"] # => "david" # cookies.size # => 2 # # Example for deleting: # # cookies.delete "user_name" # # All the option symbols for setting cookies are: # # * value - the cookie's value or list of values (as an array). # * path - the path for which this cookie applies. Defaults to the root of the application. # * domain - the domain for which this cookie applies. # * expires - the time at which this cookie expires, as a +Time+ object. # * secure - whether this cookie is a secure cookie or not (default to false). # Secure cookies are only transmitted to HTTPS servers. module Cookies # Returns the cookie container, which operates as described above. def cookies CookieJar.new(self) end end class CookieJar < Hash #:nodoc: def initialize(controller) @controller, @cookies = controller, controller.instance_variable_get("@cookies") super() update(@cookies) end # Returns the value of the cookie by +name+ -- or nil if no such cookie exist.
