This event allows developers to override the URL that page responses are submitted to.  The event function receives the original URL and must return the modified URL.

Example:

pui.overrideSubmitUrl = function(url) {
  // this will cause the user to be appended to the URL so that it shows up in the Apache server logs
  var user = pui["appJob"]["user"];
  url += "&u=" + user;
  return url;
}
