PHP-Sessions and squid-proxy

[Matthias Riechmann]

Hello!

I'm experiencing problems using sessions in php. As long as I access
my php-website with the browser using a direct connection everything
works fine. But when I activate my own or my providers proxy server a
strange phenomenon occurs: Every click on a link opens a new
php-session. No, new session is not the correct description: There is
a total of four sessions and it rotates cyclic between them.
I wrote another php-script trying to debug this behaviour and
discovered that everything works fine as long as I do not post any
GET-parameters like ?key=value. Is this a bug in PHP or do I have
misconfigured my proxy server?

I'm running the following software as webserver:
Apache/2.0.51 (Unix) mod_ssl/2.0.51 OpenSSL/0.9.7d PHP/4.3.8
PHP Version 4.3.8 (cookies are used for sessions)

I'm running Squid 2.4.6 on Debian linux

Browser is Mozilla 1.72 / Internet Explorer 6

This is the test script that works as long as I don't pass
GET-parameters:

<?php
session_set_coo kie_params(600) ;
session_cache_l imiter('nocache ');
session_start() ;
srand();
if (!isset($_SESSI ON["foo"]))
{
$_SESSION["foo"] = time()."-".rand();
}
echo($_SESSION["foo"]);
?>

Does anyone have a clue?
