1640              * must examine the queue and determine the next request to be sent.  The behavior of the
1641              * request callback function must be as follows:
1642              * <ul>
1643              * <li>If the request completed successfully invoke {@link jsf.ajax.response}
1644              * passing the <code>request</code> object.</li>
1645              * <li>If the request did not complete successfully, notify the client.</li>
1646              * <li>Regardless of the outcome of the request (success or error) every request in the
1647              * queue must be handled.  Examine the status of each request in the queue starting from
1648              * the request that has been in the queue the longest.  If the status of the request is
1649              * <code>complete</code> (readyState 4), dequeue the request (remove it from the queue).
1650              * If the request has not been sent (readyState 0), send the request.  Requests that are
1651              * taken off the queue and sent should not be put back on the queue.</li>
1652              * </ul>
