Comet: The Foundation for High-Performance Real-Time Web Apps

Comet is a collection of latency-reducing techniques for Ajax-style HTTP requests. Low-latency, browser-based, event-driven web applications are possible, overcoming the performance and scaling limits Ajax developers find when creating collaborative and real-time web applications.

Cometd is an open-source project that includes the Bayeux protocol specification, JavaScript Comet libraries based on the Dojo Toolkit, and a collection of scalable HTTP-based event servers written in Python, Java, and Perl. Cometd improves real-time user experience, and the Bayeux protocol makes it easy to choose from and use a variety of Comet servers. Applications built using the Dojo Toolkit can be deployed on any Bayeux-compliant server.
