Here are two pages that I also used in both browsers to demonstrate this problem. The session ID seems fine but not the vars. Works in IE 5, but not NS 4.08. Any ideas are appreciated.
<?php
session_register ("count");
$count++;
echo SID;
echo "email is: " . $email;
$email=$email . $count;
?>
Hello visitor, you have seen this page <? echo $count; ?> times.<p>
<php?
the <?=SID?> is necessary to preserve the session id
in the case that the user has disabled cookies
?>
To continue, <A HREF="counter2.phtml?<?=SID?>">click here</A>
