Session and forms authentication have two completely separate timeouts. See my posting on this here:

How can I handle forms authentication timeout exceptions in ASP.NET?

In Application_PreRequestHandlerExecute you need to check the ticket.

Also be sure your session and forms auth timeouts are in sync using the code I posted there. Not just setting both to say 60 minutes. Since forms auth doesn't update the 'touched' time until half of the time passes by, and session time is updated on every request, they get out of sync.
