I'm having an intermittent problem with session_register, where if I register a session variable such as:

<?
session_register("session_userid");
?>

then in the querystring pass a variable such as:

http://site/test.php?userid=xx


intermittently, the script will cache what is passed through the querystring into a session variable called $userid, and use that value for the rest of the session.

Note, it doesn't use the value of what is in $session_userid, it only creates a $userid session variable and overrides the querystring for the remainder of the session.

I have tested this by doing something like:

<?
if(session_is_registered("userid")) echo "registered\n";
?>

I will intermittantly get the word "registered" on the page.

I've searched high and low, and nobody seems to know anything about this, so I figured I would submit it to you.

I installed PHP by using the mod_php4 port from the FreeBSD ports tree in /usr/ports/www/mod_php4.  I'm also running Apache 1.3.17.

If there is any other information you'd like me to submit, let me know via e-mail and I will submit it ASAP.

Thank you,
