So, if you are interesting in building a realtime solution then you should probably first investigate WebSockets and then deal with fallbacks such as HTTP Streaming and HTTP Long-Polling.

With Comet, web servers can send the data to the client without having to explicitly request it. Because this connection is done on the server, it isnât impacted by CORS.
