Websocket support

[sj26]

It would be fantastic if NGINX Unit supported management of websocket connections supervised by language runtimes, as suggested in #124, and previously confirmed in #6 (comment). This is something hard to do correctly and efficiently in language runtimes themselves, and is a very compelling feature for a high performance application server. (I've opened this issue independently to keep track of interest in the feature.)

is there any update on this?

Here's a separate branch with web-sockets beta support in Node.js and Java: https://github.com/mar0x/unit/tree/websocket

For Node.js instead of:

var http = require('http’);
var webSocketServer = require('websocket').server;

you have to use:

var http = require('unit-http’);
var webSocketServer = require('unit-http/websocket').server;

@VBart is there a way to use WebSocket in a Java-based app? If yes, how?

I mean this https://coderwall.com/p/dahxya/implement-websocket-in-a-java-servlet works with Tomcat would it work with Unit also?

[mar0x]

@cyberquarks Yes, there is a way to use WebSocket in Java-based app. Our implementation is based on Java API for WebSocket.

Your sample is Tomcat-specific and will not work. You may use other Tomcat WebSocket examples as a starting point.
