Right, getURL cannot fetch headers if CURL is used. You could extend the
function, but unfortunately the documentation for curl_* is not so great in
PHP: http://ch.php.net/curl

There are two constants which may be used, but I can't see which of those is
more adequate:
CURLOPT_HEADER
CURLOPT_HTTPHEADER
