1850              * sending of the serialized form data (in the case of long requests in the queue).
1851              * Before the request is sent it must be put into a queue to ensure requests
1852              * are sent in the same order as when they were initiated.  The request callback function
1853              * must examine the queue and determine the next request to be sent.  The behavior of the
1854              * request callback function must be as follows:
1855              * <ul>
1856              * <li>If the request completed successfully invoke {@link jsf.ajax.response}

1858              * <li>If the request did not complete successfully, notify the client.</li>
1859              * <li>Regardless of the outcome of the request (success or error) every request in the
1860              * queue must be handled.  Examine the status of each request in the queue starting from
1861              * the request that has been in the queue the longest.  If the status of the request is
1862              * <code>complete</code> (readyState 4), dequeue the request (remove it from the queue).
1863              * If the request has not been sent (readyState 0), send the request.  Requests that are
1864              * taken off the queue and sent should not be put back on the queue.</li>
1865              * </ul>
