We are rolling out a site based on Acegi login - the user enters username/password and, if authenticated successfully, a session cookie is set on the device. Based on the presence of that cookie, the user is then allowed to continue navigating the site.
This works fine on newer devices, but on older Symbian devices (Nokia 6800, 6030), the auth process succeeds but on subsequent pages the user is dumped back to the login. We're still debugging to see if cookies aren't being passed or such, but have other developers encountered a similar issue? Perhaps I can avoid all the debugging I'm about to start!
