module ActionController #:nodoc:
class Base
# Process a request extracted from an CGI object and return a response. Pass false as <tt>session_options</tt> to disable
# sessions (large performance increase if sessions are not needed). The <tt>session_options</tt> are the same as for CGI::Session:
#
# * <tt>:database_manager</tt> - standard options are CGI::Session::FileStore, CGI::Session::MemoryStore, and CGI::Session::PStore
# (default). Additionally, there is CGI::Session::DRbStore and CGI::Session::ActiveRecordStore. Read more about these in
# lib/action_controller/session.
# * <tt>:session_key</tt> - the parameter name used for the session id. Defaults to '_session_id'.
# * <tt>:session_id</tt> - the session id to use. If not provided, then it is retrieved from the +session_key+ parameter
# of the request, or automatically generated for a new session.
# * <tt>:new_session</tt> - if true, force creation of a new session. If not set, a new session is only created if none currently
# exists. If false, a new session is never created, and if none currently exists and the +session_id+ option is not set,
# an ArgumentError is raised.
# * <tt>:session_expires</tt> - the time the current session expires, as a +Time+ object. If not set, the session will continue
# indefinitely.
# * <tt>:session_domain</tt> - the hostname domain for which this session is valid. If not set, defaults to the hostname of the
# server.
# * <tt>:session_secure</tt> - if +true+, this session will only work over HTTPS.
# * <tt>:session_path</tt> - the path for which this session applies. Defaults to the directory of the CGI script.
