2) is support to all machine? or browser?i’m newbie on web socket programing, please help me

Yes, you can build the server in any language you want, but web sockets are not a simple socket, they are sockets that “follow” a specific protocol, so make sure you read the specification of this protocol and implement it on your server so any browser will be able to stablish a connection to it.

And you can also write a client in any language, but if you’re not using javascript then I don’t see why you would use web sockets instead of using just a simple socket. But if you want to, just take a look at what data a browser sends to a web socket server and emulate it from your own client.
