apache help using xampp 2.1

[bob5731]

Hi, All
I need it to goto http://bob5731.no-ip.info/web

<?php
    if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) {
        $uri = 'https://';
    } else {
        $uri = 'http://';
    }
    $uri .= $_SERVER['HTTP_HOST'];
    header('Location: '.$uri.'/xampp/');
    exit;
?>
Something is wrong with the XAMPP installation :-(
