Khuram, Let's try a little debugging... Create a file called test.php on your server with this mark-up: <html> <head>

    <title>PHP SERVER TEST</title>

</head> <body>

    <p>
      <a href='test.php'>click</a>
    </p>
    <pre>
      <? print_r($_SERVER); ?>
    </pre>

</body> </html> This will dump the contents of _SERVER onto the screen. When you first load the page, there SHOULD be a lot of values on the screen, but if there isn't, then there's definitely something odd with your server set-up. If there ARE a lot of values on the screen, great, good start. You'll will notice that there ISN'T a value for for HTTP_REFERER, because so far there isn't a referrer (you accessed the page direct). Click on the "click" link, and the page will reload with the _SERVER array again, and this time there *should* be a value in the HTTP_REFERER. If there isn't, then I'd suggest wither your browser, firewall, virus protection software or your server is messing around with referrers for security or privacy reasons.
