How user will reach sign in page

[siri_suresh]

Hi All
I have a problem, whenever the user sign out from his session and presses browser back button then he should be taken up to sign in page not previous page. You can see this functionality in www.mail.yahoo.com site. How can i do same thing using PHP and JavaScript. Example code will do more help for me. Please help me in regard
Thank you
Suresh

I too have been fighting with this "bug". The PHP session is not being closed properly. Something is left on the client so that when they press the back button, the server immediately recreates the session. At the moment, I can't figure out what to do - but I tell the client to close the browser in my logout page. That!!! closes the session.
