Current AJAX applications use polling to communicate changes data between the server and client. Some applications,
such as chat applications, stock tickers, or score boards require more immediate notifications of updates to the
client. Comet is an event based low latency server side push for AJAX applications. Comet communication keeps one of
the two connections available to the browser open to continously communicate events from the server to the client. A
Java based solution for Comet is being developed for Glassfish on top of the Grizzly HTTP connector. See Enabling
Grizzly by Jean-Francois Arcand for more details.
