Session Store Issues on Production Server

Hello,

I am using AuthLogic as my authentication gem. Everything is great on
my development server. When I upload to my passenger driven
production server at Dreamhost, the sessions are persisting
relentlessly. In other words, a user cannot log out. I have tried
implementing the Active Record session store and have changed
the :secret key in initializers/session_store.rb, but for some reason,
it is not resetting my users. Another interesting note is that in the
Appplication Controller if I force current_user_session to return
false, the user is logged out (of course). The problem seems to be
coming from user_session.delete.

Has anyone encountered this before? Is there something in Rack that
is holding this back?

Thanks!

Another interesting note is that this problem is agnostic to the
browser. Deleting sessions and cookies has no effect on it
whatsoever. This leads me to believe that the issue is server based
with Rack somewhere.

It has been suggested that this issue may be related to the version of
Passenger that is running on Dreamhost. I have been able to isolate
the issue to Passenger because it does not occur when the site is
running on mongrel. I believe the source of the issue is in the way
Passenger is dealing with the sessions. Has anyone had any experience
with this?
