One more change. With CURLOPT_NOBODY we can do a header-only with CURL.

So remove this hint "2=fetch header only (will be ignored when using CURL)"

And add after
  curl_setopt($ch, CURLOPT_HEADER, $includeHeader ? 1 : 0);
this
  curl_setopt($ch, CURLOPT_NOBODY, $includeHeader==2 ? 1 : 0);

Masi

PS: Tested with this script:

<?php

$ch = curl_init();

// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.activesolution.at/");
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_NOBODY, true);

// grab URL
echo curl_exec($ch);

// close CURL resource, and free up system resources
curl_close($ch);

?>
