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
Technologies cntd.
