I have an odd problem I don't ever remember having before.
If I access my app with Safari or Firefox, I can login and maintain a consistent session. Tailing the log file, I see the same session ID evertime I hit my apps pages.
Now, I open up IE7 on my PC. I try to login, and the server thinks the login worked fine, but after I get redirected I am not logged in. After further investigation, every single hit from my IE7 generates a new session with a new session id.
It's like IE7 refuses to accept a cookie from this site. The odd part is that I have a 1.2.3 version of the site running fine in production right now. The only thing I can think of that changed is upgrading to Rails 2.0.2. We are using ActiveRecord store for both apps, since the session might get a little bigger than 4K.
Any ideas? This is stumping me. Also are there any good tools for testing when cookies are set and cleared?
