  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',

$request->setMethod(HTTP_Request2::METHOD_GET);
$request->setConfig(array(
  'follow_redirects' => TRUE
));
try {
  $response = $request->send();
  if ($response->getStatus() == 200) {
    echo $response->getBody();
  }
  else {
    echo 'Unexpected HTTP status: ' . $response->getStatus() . ' ' .
    $response->getReasonPhrase();

}
catch(HTTP_Request2_Exception $e) {
  echo 'Error: ' . $e->getMessage();
