The Tech: Comet

Updates from a real-time data source

Bayeux protocol: Comet transport : method of sending Comet events

Over long-lived HTTP connections

Continuations: Request handling thread goes to sleep until it gets a message or times out. On timeout a request is made for a new connection. When the thread on the server receives a message, it wakes

up and sends the message payload sent back to the browser (which also implies that it's time to send a new request).

Improved throughput and decreased latency and server load
