Bypassing session integrity check

I've a PDA application that posts data to a RoR web app. But I don't include a 'authenticity_token' field and the server is returning 'The change you wanted was rejected'. Removing 'config.action_controller.session' from environment.rb doesn't seem to work. Is there any way to tell RoR to ignore the session check for a set of controller actions?

Thanks, Mark

You can use the protect_from_forgery method, found the answer here:
