loout function

[Proogeren]

I have a master page that contains a logout button. If you click this a session value is set (using https so sessions are ok). My problem is that if I press the logout button I redirect the user to another location. All good. but if I click the back button in the browser I can see the previous page. Page_Load is not triggered in my masterpage so I can not see if the session value allows the user to see the page or not..

What can be done to prevent this??? Without using the login controls that exist in C#?

If the page caching then this is what you look at. HTH.

solved with

            Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1));
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.Cache.SetNoStore();

in my master page's Page_Load event :)
works in both FF and IE
