    $urlWithoutProtocol = "192.168.200.11";
    $request         = "";

    $exHeaderInfoArr   = array();
    $exHeaderInfoArr[] = "Content-type: text/xml";
    $exHeaderInfoArr[] = "Authorization: "."Basic ".base64_encode("authen_user:authen_pwd");
 
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $urlWithoutProtocol);
