Sessions nightmare continue...

Hi all, Still no luck with sessions. I have installed an older version: 4.3.1 and have register_globals=Off I have 2 test pages a1.php and a2.php All I want to do is register a session variable, set a value for it and then in a2.php check that it is still registered and view the session's value. a1.php: <? session_start(); header("Cache-control: private"); // IE 6 Fix. if(isset($_POST['Submit'])) { $_SESSION["login"]="inside"; session_write_close(); header("Location: a2.php"); exit(); } ?> I can successfully register the session variable and set the value of it on page a1.php but when I go to page a2.php the session variable is not set and the value isnt set either. a2.php: <? session_start(); header("Cache-control: private"); // IE 6 Fix. if(!isset($_SESSION["login"])) echo("<br>session variable NOT set"); else echo("<br>session variable set"); echo("<br>session ID: " . session_id()); echo("<br>session value: " . $_SESSION["login"]); ?> I have been trying to get this to work for ages with no luck. I have been reading the manual and have googled and cant seem to find the problem. if anyone can help that would be great. thanks in advance Angelo -------------------------------------------------------------------- Disclaimer This e-mail transmission contains confidential information, which is the property of the sender.
