Hi,

I'm using PHP 4.4.4. What is the best way (I assume regular
expressions would be involved) to get the domain from the
$_SERVER['HTTP_REFERER'] variable? By "domain" I am referring to (for
example), google.com, instead of groups.google.com. In other words, I
don't care about sub-domains.

Thanks, - Dave
