ASP .NET Login Session How to destroy session object when logging out from Home Page?

Question

I have created a website. I login with username and password and after authenticating i redirect the user to Home Page. When the user clicks Logout, they are redirected to the Login Page. But after this when i click the BACK button on the browser, it again goes back to the Home Page with that user's login credentials. I have used Session["username"]=null in the Page_Load function of Home Page. How to avoid going back to the Home Page when the BACK button is clicked by the User??

Answer 1

Most of the times browser back button did not get data from server it usually get it form browser cache. I think you should try removing page from browser cache on logout event,it will solve your problem automatically.

Hi Vinodh,

behind logout button code body use FormAuthentication.SignOut()
