SockJS - WebSocket emulation done right - GitHub: "SockJS has ambitious goals:
Simple browser-side and server-side APIs, as close to WebSocket API as possible.
Well documented scaling and load balancing techniques.
Transports must fully support cross-domain communication.
Transports must fall back gracefully in case of restrictive proxies.
Connection establishment should be fast.
No Flash on the client side, Javascript only.
Client-side Javascript must be reasonably well tested.
Additionally the server side code should be simple, in order to lower the cost of writing servers for different languages.
