Flash Intro / isset() problem

Hi,

I’ve made a WordPress site for a friend. He wants a flash intro in the beginning.

I’ve tested this idea on my home server using this topic and it works like a charm.

Now I’ve set everything up on the real active server and the intro keeps looping. In the code:

<?php
    session_start();
    if(!isset($_SESSION['flashIntroShown']))
    {
        $_SESSION['flashIntroShown'] = 1;
        header('Location: https://yourwebsiteURL.com/intro.html');
    }

define('WP_USE_THEMES', true);

require('./wp-blog-header.php');
?>

I think it is going wrong with the isset() function. If i redirect it to google.com and try again it is still redirecting me, but it should go to the actual site. It might have something to do with a PHP version issue.

Anny suggestions
