When the forms authentication cookie expires, I'm trying to override the default behavior of redirecting to the login page, and pass a value on the querystring (timeout=true), so I can inform the user what has happened.
I'm prepared to work out the logic to know if they have actually timed out or not, I just don't know the best place to override where the response is redirected to the login page. The best place I can find is "FormsAuthentication_OnAuthenticate", but perhaps you know of a better place?
Thanks!
