Why are my forms authentication tickets expiring so fast?

Question

I\'m using forms authentication in an ASP.NET application. I configure the FormsAuthenticationTicket to expire in 1 year but it actually expires after 1 hour or so.

My guess is that the cookie is expiring before the ticket. The above article shows you ways to debug to see if that is indeed the case.
