Can someone tell me how to grab domain referred in ASP ?

Hi,

*** PM OFFERS - WILL PAY ***

Can someone tell me how to grab domain referred in ASP ?
Mainly I done this piece of code in PHP which works well but I would like to translate this code into ASP.
Please, could someone help me?

<?php

echo ('Referring domain:</br>');
$ref = $_SERVER[SERVER_NAME]; // grab domain
echo ($ref.'<br/>'); // show domain

if ($ref == "www.domain.co.uk") { 
  echo ('This domain is correct.');
} 
else {
  echo ('This domain is wrong.<br/>');
  echo ('Added into HEAD section following META:<br>&lt;META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW"&gt;');
  ?>
  <META NAME="ROBOTS" CONTENT="NOINDEX, NOFOLLOW">
  <?
}

?>

The server variable "http_referer" holds the referring information. You can grab it with:

ReferringDomain=request.servervariables("http_referer")

Then to check it, you might do something like this:

If ReferringDomain="www.domain.co.uk" then
    'Correct domain
else
    'incorrect domain
end if
