module ActionController #:nodoc: # Cookies are read and written through ActionController#cookies. The cookies being read are what were received along with the request, # the cookies being written are what will be sent out with the response. Cookies are read by value (so you won't get the cookie object # itself back -- just the value it holds). Examples for writing: # # cookies[:user_name] = "david" # => Will set a simple session cookie # cookies[:login] = { :value => "XJ-122", :expires => 1.hour.from_now } # # => 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: # # * <tt>value</tt> - the cookie's value or list of values (as an array). # * <tt>path</tt> - the path for which this cookie applies. Defaults to the root of the application. # * <tt>domain</tt> - the domain for which this cookie applies. # * <tt>expires</tt> - the time at which this cookie expires, as a +Time+ object. # * <tt>secure</tt> - whether this cookie is a secure cookie or not (default to false). # Secure cookies are only transmitted to HTTPS servers. module Cookies protected # Returns the cookie container, which operates as described above. def cookies CookieJar.new(self) end # Deprecated cookie writer method def cookie(*options) response.headers['cookie'] << CGI::Cookie.new(*options) end end class CookieJar < Hash #:nodoc: def initialize(controller) @controller, @cookies = controller, controller.request.cookies super() update(@cookies) end # Returns the value of the cookie by +name+ -- or nil if no such cookie exists.
