Passing Session ID ... Please HELP

I have problem with passing the session ID, although session.use_trans_sid is set to 1 but the SID isn't inserted automaticaly in the URL if the cookies are disabled in my browser!

It should works as its mentioned at http://www.php.net/manual/en/ref.session.php

These are my test scripts:

Session1.php:
<?
session_start();
$IPAddress = getenv ("REMOTE_ADDR");
session_register("IPAddress");
echo "My IPAddress is $IPAddress";
?>
<a href="Session2.php"> Click here to test session variable</a>

Session2.php:
<?
session_start();
$IPAddress = $HTTP_SESSION_VARS[IPAddress];
echo "My IPAddress is $IPAddress";
?>

Do I have to do extra coding to make the SID inserted automaticaly if the cookies are disabled?

PHP Version: 4.0.6

From the manual:

Note: For PHP 4.1.2 or less, it is enabled by compiling with --enable-trans-sid. From PHP 4.2.0, trans-sid feature is always compiled.

Have you checked your compile options?
