Variable ajaxErrorHandler

Implements this function to be called if the request fails. The function receives four arguments: The XHR (XMLHttpRequest) object, a number describing the status of the request, a string describing the text of the status, and a number describing the retry value to re-send.

For example,

zAu.ajaxErrorHandler = function (req, status, statusText, ajaxReqTries) {
     if (ajaxReqTries == null)
        ajaxReqTries = 3; // retry 3 times

   // reset the resendTimeout, for more detail, please refer to
   // http://books.zkoss.org/wiki/ZK_Configuration_Reference/zk.xml/The_client-config_Element/The_auto-resend-timeout_Element
   zk.resendTimeout = 2000;//wait 2 seconds to resend.

   if (!zAu.confirmRetry("FAILED_TO_RESPONSE", status+(statusText?": "+statusText:"")))
      return 0; // no retry;
   return ajaxReqTries;
}
