Nginx & Comet: Low Latency Server Push – igvita.com

Turn your Nginx server into a fully functional Comet server with the nginx_http_push_module plugin.

Instead of using a custom framework, Leo's plugin exposes two endpoints on your Nginx server: one for the subscribers, and one for the publisher. The clients open long-polling connections to a channel on the Nginx server and start waiting for data. Meanwhile, the publisher simply POST's the data to Nginx and the plugin then does all the heavy lifting for you by distributing the data to the waiting clients. This means that the publisher never actually serves the data directly, it is simply an event generator! It is hard to make it any simpler then that.
