WebSocket-multiplex SockJS example
2+
==================================
3+
4+
To run this example, first install dependencies:
5+
6+
npm install
7+
8+
And run a server:
9+
10+
node server.js
11+
12+
13+
That will spawn an http server at http://127.0.0.1:9999/ which will
14+
serve both html (served from the current directory) and also SockJS
15+
service (under the [/multiplex](http://127.0.0.1:9999/multiplex)
16+
path).
17+
18+
With that set up, WebSocket-multiplex is able to push three virtual
19+
connections over a single SockJS connection. See the code for details.
