session variables lost while redirecting in linux

[appadurai]

Dear All,
I have just started working in php,
I have a problem in redirecting session variables which is lost and not able to retrieve the session variable in the redirected page.
I am posting the code below., Could someone please help me to fix the problem. I am using php 4.3.9 and apache 2.0.52.
Thanks in advance.

CallHeader.php
<?php
global $clientMachine ;
$clientMachine = "appadurai" ;
session_register(clientMachine);
header("location:CheckGlobal.sgp");
?>

CheckGlobal.php
<?php
session_start();
echo "MACHINENAME $clientMachine";
?>

should it be session_register($clientMachine);?

Thank you for the reply,
I tried that but it did not work. I made a mistake in the thread posted, my actual session_register call looks like below.
session_register("clientMachine")

The same code works on another linux machine with different php and apache versions.

try this:

CheckGlobal.php
<?php
session_start();
echo "MACHINENAME" . $_SESSION['clientMachine'];
?>
