So, you'll supposedly have an "entrance" page: [index.php] <?php setCookie('haveCookies',1); Header('Location: http://site/main.php'); ?> [main.php] <?php if (empty($HTTP_COOKIE_VARS['haveCookies'])) { return include "error.php"; } // the rest of php code goes here. ?> And BTW of globals off, ppl complain it's a lot to type (yap, one of the virtues of a programmer, laziness), but hey you can assign those long-named arrays to something simple, so if you have to work a lot with, say, GET vars, just say $GV = $HTTP_GET_VARS; and go ahead w/ $GV. ciao -- teodor
