I m working on a webapplication that shows secured data.after I sign out of the site, if I press the back button on the browser then the previous page is shown again.I want to avoid it.I want the browser to take me to the log in screen if I press the back button after logging Out. How to do it?

Well i faced the same problem but my case was easy so i found a way to empty all sessoins in cuding those that contains the connection string to the database. so whenever the user click on the back button he can see noting and if he clicks any button he would get an error page.
i know it is not the right way to do but i did not find any other solution.


thanks

A good way to do this is to set page expiration such that all pages expire immediately. This way, even when you hit "Back", the browser goes to the server again for a fresh page request. Now because you logged out, the page should send you back to the login page.
