As I wrote some lines of code,

<?php
....
$client = new Zend_Http_Client('uri_path');
$request = $client->request('head');
...
?>

so far so good, everything worked just perfect until I deployed the “working” code on the production server. Than odd enough some requests just crashed. Not all – just some of them.

Another strange thing was that no exception was thrown.

Maybe using more my intuition instead of my brain I just tried to request the head using capital letter – HEAD. And as everything was strange enough, yet again this solution happened to be working! That solved my problem.

<?php
....
$client = new Zend_Http_Client('uri_path');
$request = $client->request('HEAD');
...
?>
