I am building an application in MasterPage. Now I have an Login page from which my user is redirected to the masterpage when he is loging in. For authentication I am using FormsAuthentication and it works fine.
Now when the user is on the MaseterPage I have a logout button. If i click on that button I will be redirected to my LoginPage, but if I click on the back button in the browser , the last page before clicking 'Logout' is rendered again.,,,how to avoid it....
(iam using ASP.NET and C#)
