Logout help

[182x]

hey guys, I am deadling witha very old version of PHP and I have to use $HTTP_SESSION_VARS for my session variables and I have created a simple logout script which can be seen below however I am getting the error message: "Warning: Trying to destroy uninitialized session in /test/cgi-bin/file/logout.php on line 2"

Any ideas where I have went wrong? Thanks.

[code]

<?php
session_destroy();
header("location:back.php")
?>

on some systems i've found... that session_destroy(); has no effect, try putting this... or perhaps just unset(); all of your main session variables...

[code]
<?
@session_destroy();
@session_end();
header("location:back.php")
?>
[/code]

You can also use-
$_SESSION = array();
which is faster.

Orio.
