I submitted a ticket about this, but I thought perhaps I should ping this mailing list as well.
When deploying an an app that was upgraded to run on Rails 2.0 and use cookie sessions, users that are logged into the site receive an error: CGI::Session::CookieStore::TamperedWithCookie when they first visit
the site. When they refresh once, this error will no longer appear.
However, I can't figure out how to work around them seeing an Application Error screen the first time. Is there any way to rescue_from this error, or otherwise avoid encountering it all together?
If you change the name of the cookie used then the app won't see the
old cookie at all, which should handle things.
