Code a real-time survey with HTML5 WebSockets

This article first appeared in issue 217 of .net magazine - the world's best-selling magazine for web designers and developers.

WebSockets are a part of the HTML5 specification, and the simplest way of looking at them is that they set a standard for creating long-running bi-directional connections between a browser and a server. With this connection in place, browsers can send messages back to the server (like quicker Ajax) and, even more crucially, the server can push new information to connected clients as it becomes available. WebSockets allow extremely low latency communication with little overhead.
