Just rewrote this quick, tested aswell - should work fine. Might not be as effective as a php header redir, but it'll still work.
Should work fine, didn't test at all. As Will said, i'd double check with adversal to make sure it's allowed in TOS. I'v dealt with them a few times with some things and they're usually pretty quick to get back to you.
echo "<meta http-equiv='REFRESH' content='10; URL=$url'>";
You are now being redirected. <? echo "<a href='$url'>Click here to avoid the wait.</a>"; ?>
