Is there a way to keep a page from rendering once a person has logged out but hit the “back” button?

Question

I have some website which requires a logon and shows sensitive information.

The person goes to the page, is prompted to log in, then gets to see the information.

Answer 1

Please look into the HTTP response headers. Most of the ASP code that people are posting looks to be setting those. Be sure.

The chipmunk book from O'Reilly is the bible of HTTP, and Chris Shiflett's HTTP book is good as well.
