 * @assertion void close({

 * Shut down the HTTP client. If force is false (the default) the HttpClient
 * will be kept alive until all active connections are done. If force is true
 * any active connections will be closed to immediately release all resources.
 * These closed connections will receive an error event to indicate that the
 * client was shut down. In both cases trying to establish a new connection
 * after calling close will throw an exception.
