simple redirection script (masks referrer) please help

I want one page to redirect to another.
I also want it to be a random URL from an array.
But the tricky part is... that I want the referral to show that page.

I tried this:

<?php

$url[0] = "xxxxxxxxxx";
$url[1] = "xxxxxxxxxx";

srand ((double)microtime()*1000000);
$randomnum = rand(0, count($url)-1);
header ("Location: $url[$randomnum]");
?>

Code (markup):

This works but for the referral, it doesn't give this page (random.php)... instead, it gives the page that came before it. (the page that links to random.php)

I also tried redirection via the meta tag.

<meta http-equiv="refresh" content="2;url=xxxxxxxxxx">

Code (markup):

Here, the problem was that the referral would end up being N/A. (i want the referral to come up as http://......../random.php)

Any suggestions?
