hi,

I'm building a .NET based login pages and was wondering how do i prevent users from going back to the previous page by clicking the back button. When i've logged out of my secured pages, using FormsAuthentication.SignOut() , i'm still able to reach the secured pages by clicking on back. I've noticed that some other secure sites like yahoo mail and hotmail have done it successfully. When user click on the back button, a message saying ' the session has already expired' kind of stuff.

I think it is important that your application prevent or try to prevent browsers from caching those pages, otherwise it will be out of your control.
