Hi.

I found that sessions are disabled and can’t login with  
restful\_authentication.

Session and login works fine with “config.cache\_classes = false” but  
it doesn’t work with “config.cache\_classes = true”.  
It doesn’t show any errors, but redirect to login page.  
It seems to be post nothing.

Does it have to do with session\_storre, active\_record\_store,  
protect\_from\_forgery, or other configrations?

my enviroments is Rails 2.2.2 Ruby 1.8.6

Any ideas?
