Detailed Description

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('<?xml version="1.0"?'.'><methodCall><methodName>example.search</methodName></methodCall>');
            $service->send();
    if ($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;
