I've got a site running php, and I need it set so that any page that is loaded defaults back to an agreement page before any page on the site can be loaded. From that agreement page, either the user agrees to the terms and can proceed to view all of the pages on the site, or they disagree and are directed to an exit page. Use of cookies would be fine.
The site is located at [login to view URL] It currently works OK with IE7, but not with Firefox.
