Unless I'm mistaken, you should adopt something closer to my code
instead because it may not be safe for you to trust the contents of
$_SERVER['SERVER_NAME']. If you use the switch() construct, you're
effectively whitelisting the permissible domains. It should be easy
enough unless you have dozens of domain names or more or unless the
domain names are constantly changing...
