The WebSockets prototype for Internet Explorer has been just been updated on html5labs.com, this brings the implementation inline with the 09 protocol version that was released 10 days ago on the 13th of June.
If you have used WebSockets before then you will know that you need to make sure the client version is the same as the server version, so you’ll be glad to know Microsoft have updated both.
So What is HTML5labs.com?
HTML5Labs.com is Microsoft’s way of brining you interesting HTML5 implementations so that you can test and provide feedback on them, with the caveat that the implementation will change and when changes are made there will likely be breaking changes.
So what are WebSockets?
WebSockets solves the problem with the real time web without the performance overhead of polling.
