Rails 3 and Controller Instance Variables Inside a Helper

In my Rails 2.x applications i could access controller instance variables happily inside my application_helper.rb but with 3.0 that is no longer the case.

Specifically I'm attempting to access the special controller instance variables that are described in http://github.com/rails/rails/blob/master/railties/guides/source/debugging_rails_applications.textile namely: @_response, @action_name, @url, @_session, @_cookies, @performed_render, @_flash, @template, @_params, @before_filter_chain_aborted, @request_origin, @_headers, @performed_redirect, @_request

What's up here? Usually Google is my friend here but nobody who has reported this elsewhere (like on Stack Overflow) seems to have found an answer.

Thanks in advance.

i think the dont require the @ anymore , try it out, it was like that with the request, it no longer requires @ at its beginning

Thanks but that didn't do it unfortunately.
