Uhm, it could be done with cookies...
Tested a bit with t, and it looks to me it could be done that way. Need to learn about session cookies to perfect it
<?php
if (isset($_COOKIE['betaONEpage'])) {
if ($_COOKIE['betaONEpage'] == "Portal") { $betaONEpage = "/portal/"; }
else { $betaONEpage = "/forums/"; }}
else { setcookie("betaONEpage", "Portal", time() + 60, "/", "
www.betaone.net" ); }
?>
and
<FRAME name="main" src=<? print "$betaONEpage" ?> scrolling="auto">
