CURL and basic authentification

Hi, I need to know why when I send petition with CURL like this, the machine I am sending to approves my authorization, but gets an empty request. What can I do to debug this? function getResponse($request, $type){ $curl_interface = curl_init(); curl_setopt($curl_interface, CURLOPT_HTTPHEADER,array("Authorization: Basic " . base64_encode(AZOR_USR . ":" . AZOR_PASSWORD))); curl_setopt($curl_interface, CURLOPT_URL,AZOR_URL); curl_setopt($curl_interface, CURLOPT_POST, 1); curl_setopt($curl_interface, CURLOPT_POSTFIELDS,$request); curl_setopt ($curl_interface, CURLOPT_RETURNTRANSFER, 1); $xml_response=curl_exec ($curl_interface); curl_close ($curl_interface); return $xml_response; } -- Diana Castillo Global Reservas, S.L.
