What's wrong with my RoR Cookieless Session Reasoning?

[moephan]

Hello,

I am writing a mobile version of my site, meaning that I cannot rely on cookies being present in the browser. In order to enable cookieless sessions in rails, I have:

1. Uncommented config.action_controller.session_store = :active_record_store in enviornment.rb
2. ran rake db:sessions:create
3. Checked and saw that the sessions table was created, and for each page visited, a row is added to the database
4. Set config.action_controller.session = {:session_key => '_session_id', #secret in environment.rb
5. Set session:cookie_only => false in the application controller (application.rb)
6. Pass _session_id=session.session_id as a parameter in every form post, or hypertext link
7. Turn off cookies for the site in the browser
8. I turned off #protect_from_forgery in application.rb

However, the session is never passed between pages. I am testing with two pages and a controller action. I start at the view for food/index, then go to the login page at the view for user/signin, this page has a form that posts to the action user/login which redirects back to food/index.

The log shows that the session paramaters are being passed, but the session is not being set from it for some reason:

Am I missing a step? Is there a problem with my reasoning regarding how to configure this?

Thanks in advanced.
