Lazzerous,
Sorry mate but I think you're wrong. You can use the <META http-equiv...> anywhere in your pages (I have just done it).
Anyway back to the problem in hand, I wasn't trying to put the <META ..> tag in the <BODY> anyway!!!
What I was suggesting was:
eg.
****LOGIN PAGE****
<form action="newpage.php3" method="post">
<input type="text" name="userid">
<input type="submit" value="log-in">
</form>
****END OF LOGIN PAGE****
****newpage.php3****
<head>
<meta http-equiv="refresh" content="30; url=www.php.net/ex.php?user=<? echo $userid ?>" >
</head>
****END OF newpage.php3****
Therefore when redirected www.php.net would take the variable $user which would be equal to the userid entered on the first page
