/**
* This class is used to make proxied service requests via the HTTP POST method.
*
* Usage Example:
*
* try {
* $service = phpCAS::getProxiedService(PHPCAS_PROXIED_SERVICE_HTTP_POST);
* $service->setUrl('http://www.example.com/path/');
* $service->setContentType('text/xml');
* $service->setBody(''example.search');
* $service->send();
* if ($service->getResponseStatusCode() == 200)
* return $service->getResponseBody();
* else
* // The service responded with an error code 404, 500, etc.
* throw new Exception('The service responded with an error.');
*
* } catch (CAS_ProxyTicketException $e) {
* if ($e->getCode() == PHPCAS_SERVICE_PT_FAILURE)
* return "Your login has timed out. You need to log in again.";
* else
* // Other proxy ticket errors are from bad request format (shouldn't happen)
* // or CAS server failure (unlikely) so lets just stop if we hit those.
* throw $e;
* } catch (CAS_ProxiedService_Exception $e) {
* // Something prevented the service request from being sent or received.
* // We didn't even get a valid error response (404, 500, etc), so this
* // might be caused by a network error or a DNS resolution failure.
* // We could handle it in some way, but for now we will just stop.
* throw $e;
* }
