public function CasSubscriber::on403 in CAS 8

Handle 403 errors.

Other request subscribers with a higher priority may intercept the request and return a 403 before our request subscriber can handle it. In those instances we handle the forced login redirect if applicable here instead, using an exception subscriber.

Parameters

\Symfony\Component\HttpKernel\Event\GetResponseForExceptionEvent $event: The event to process.

    if ($response) {
      $event
