You can also add meta tags that will prevent caching, since your browser is displaying a cached page. Check Microsoft instructions for IE at link below:How to prevent going back to previous page using back button after you logout in asp?
If you have classic asp, you can do a ';session.abandon()'; in the logout page, and they should not see the info if they refresh by going back.





if you have asp.net you can use the built in login/out controls.
