jQuery or JS library for easy work with HTML5 Websockets and long polling?

Question

PHP

Suggest a library (JQuery or JS) to work with Websockets and long polling in 1-3 lines.
If Websockets are not supported, then by itself it works with the help of long polling.

Just in case, php is used on the server, and if not Websockets, then Post variables will be accepted.

What doesn't fit?

Well, if Post are variables, then you can use regular AJAX
and more, https://code.google.com/p/jquery-websocket/
Anyway, Google to the rescue
