WebSocket-multiplex SockJS example
==================================
This example is a copy of example from
[websocket-multiplex](https://github.com/sockjs/websocket-multiplex/)
project:
* https://github.com/sockjs/websocket-multiplex/
To run this example, first install dependencies:
npm install
And run a server:
node server.js
That will spawn an http server at http://127.0.0.1:9999/ which will
serve both html (served from the current directory) and also SockJS
service (under the [/multiplex](http://127.0.0.1:9999/multiplex)
path).
With that set up, WebSocket-multiplex is able to push three virtual
connections over a single SockJS connection. See the code for details.
