Before we get 100+ long threads about pros-and-cons of WebSockets and pros-and-cons of jQuery core using them or wrapping them in any way. Before any of that, here are a few simple facts about WebSockets, today.
- Q1:: Are WebSockets, actually part of HTML5 ?
- A1 :: No ( They were developed as part of HTML5 originally. )
- A2:: No ( WebSockets is not part of HTTP; it's a separate protocol and needs separate servers (though it can be integrated with HTTP servers in certain cases).
- A3:: No ( WebSockets can be encrypted using TLS. One can not run raw HTTPS over WebSockets, though, that wouldn't make much sense.)
If you wish to develop a "WebSockets jQuery plugin", feel free to do it.
( I very much doubt that WebSockets will be "covered" by jQuery core, any time soon. )
