sander,
this isn't so much a problem with people using the back button or whatever,
but if you set all your pages not to cache
header("Expires: 0");
header("Cache-Control: no-cache");
will do that, then also require a cookie once they are logged in. during the
logout process (and have the cookie expire in 10 minutes or something) you
kill the cookie/session then if someone tries to access the secured pages,
they don't have a cookie and are denied access.

// Subject: [PHP-DB] disable backbutton
//
//
// Hello,
//
// I would like to make a page expire or disable the backbutton
// (clear the
// history).
// Why? I'm developping a database-related programm in
// php/mysql and people can
// log in and out, but nobody should be able to use the
// backbutton to be in
// the system again as the user that just logged of.
//
// Can somebody help me?
// Thanks in advance!
