Using Omeka through a proxy server


I am a system admin in Facultad de Ciencias Sociales in Argentina, and I’m currently working on a digital library project using Omeka.

The web server hosting our Omeka site is located behind a proxy server, So, I’m wondering if it’s possible to configure omeka to communicate through the proxy.

We need to pass the request through the proxy for the plugin OAI-PMH-Harvester.

We use an auto_prepend_file in php.ini like this :

<?php stream_context_set_default( array( 'http' => array( 'proxy' => 'tcp://', 'request_fulluri' => true, ), 'https' => array('proxy' => 'ssl://', 'request_fulluri' => true, ) ) ); and don't work. Too we defined http_proxy in /application/libraries/Zend/Http/Client/Adapter/Proxy.php but nothing. Thanks for any help ! Sincerely, Eleonora
