Snippet: Client setting a cookie header

[trasherdk]

I think this needs to be split up, and wrapped in Promise to make the example more understandable.
It'll work, but is a bit too simple for node-test-snippets

'use strict';

const WebSocket = require('ws');

const server = new WebSocket.Server({ port: 0 }, function () {

  // client wrapped by server
  const client = new WebSocket(`ws://localhost:${server.address().port}`, {
    headers: { Cookie: 'yummy_cookie=choco' }
  });

  client.on('close', function () {
    server.close();
  });

});

server.on('connection', function (websocket, request) {
  console.log(request.headers.cookie);
  websocket.close();
});
