Page has expired

Hi Experts,

In my asp.net application, I have a login screen. The user loggs in by keying in the correct userid & pwd. He can logout by clicking on the logout button whcih clears the all session (including Session.Abandon) and takes you back to the login page. However, I can click on the back button on the browser to go to the previous page. Is there any way to disable this?? I have seen this in many application esp. email programs.

Please help

Regards
Ganesh

U cant disable the back button.You can prevent the user to go to previous page by redirecting to the same page.You can achieve this by javascript using history.go().
if(history.go(-1))
history.go(0)
Here -1 represents the previous page and 0 represents the current page.Hope this helps you.

Thanx Santhi for your reply.

actually what I wanted to achieve is this:
If you log on to yahoo or hotmail, and then logoff by clicking the log off link, you cannot go back to your inbox by clicking on the back button. If you do so, you will be shown a message "Page has Expired". I would like to bring into my application a similar feature.

Do you have any solution to the above problem??

Thanking you in advance
