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?
