Upgraded to Rails 2.0.2, except that we maintain vendor/rails/actionpack/lib/action_controller/routing.rb from Rail 1.2.6 (at least for now), so that Routes don't change. We still get to enjoy Rails's many new features. Also fixed a bug in Chunk-handling: disable WikiWord processing in tags (for real this time).

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.
|
|
# * <tt>http_only</tt> - whether this cookie is accessible via scripting or only HTTP (defaults to false).
