Comet (programming)

From Wikipedia, the free encyclopedia

In web development, Comet is a neologism which describes a set of techniques that uses long-lived HTTP connections to enable low-latency, event-driven communication between a web server and a web browser.[1] Like DHTML and Ajax, Comet is not a technology in itself, but a term that refers to the use of a group of technologies.

Although the term was coined in a March 2006 blog post by Alex Russell,[2] the concept is several years older and has been known by various names, including Ajax Push,[3] Reverse Ajax,[4] JSONRequest Duplex,[5] HTTP server push,[6] HTTP streaming, and Pushlets, among others.[7]
