Surfing history

I have been doing this e-commerce site and I have been having some problems with the browser saving an offline copy of my site here's the scenario: When the userlogs in the website will produce cookies for the session and for the usrid to make transactions possible when he logs out the session or the cookies will be deleted or disabled .... but when I surf the website as I log off it doesn't refresh by itself I have to refresh every page before it will know that the user has logged of... Is there anyway that this can be done automatically when you log in and log out... I have remedied this problem when you use the links to navigate throughout the site but when you type the exact URL on the address box this is what happens... I made a PHP redirection page to accomplish this is ... thx Raymond __________________________________________________ Do you Yahoo!? Yahoo!
