+Multiple servers sharing data with each other using the *W3C WebSocket API*
+--------------------------------------------------------------------------
+This is a simple example multiple clients will automatically connect to the server and will able to sharing data with each other in realtime.
+Example using the [W3C WebSocket API](http://www.w3.org/TR/websockets/).
+
+```javascript
+var WebSocketServer = require('websocket').server;
+var http = require('http');
+
+var server = http.createServer(function (request, response) {
+  console.log((new Date()) + ' Received request for ' + request.url);
+  response.writeHead(404);
+  response.end();
+});
+server.listen(8000, function () {
+  console.log((new Date()) + ' Server is listening on port 8080');
+});
+
+
+const getUniqueID = () => {
+  const s4 = () => Math.floor((1 + Math.random()) * 0x10000).toString(16).substring(1);
+  return s4() + s4() + '-' + s4();
+};
+
+wsServer = new WebSocketServer({
+  httpServer: server,
+  // You should not use autoAcceptConnections for production
+  // applications, as it defeats all standard cross-origin protection
+  // facilities built into the protocol and the browser.  You should
+  // *always* verify the connection's origin and decide whether or not
+  // to accept it.
+  autoAcceptConnections: false
+});
+
+function originIsAllowed(origin) {
+  // put logic here to detect whether the specified origin is allowed.
+  return true;
+}
+
+var clients = {};
+
+wsServer.on('request', function (request) {
+  var userID = getUniqueID();
+
+  if (!originIsAllowed(request.origin)) {
+    // Make sure we only accept requests from an allowed origin
+    request.reject();
+    console.log((new Date()) + ' Connection from origin ' + request.origin + ' rejected.');
+    return;
+  }
+
+  var connection = request.accept('echo-protocol', request.origin);
+  clients[userID] = connection;
+
+  console.log('connected: ' + userID + ' in ' + Object.getOwnPropertyNames(clients));
+  connection.on('message', function (message) {
+    if (message.type === 'utf8') {
+
+      for (key in clients) {
+        if (clients[key] != clients[userID]) {
+          clients[key].sendUTF(message.utf8Data);
+          console.log('sent Message to: ', clients[key]);
+        }
+      }
+    }
+    else if (message.type === 'binary') {
+      for (key in clients) {
+        console.log('Received Binary Message of ' + message.binaryData.length + ' bytes');
+        connection.sendBytes(message.binaryData);
+      }
+    }
+  });
+  connection.on('close', function (reasonCode, description) {
+    console.log((new Date()) + ' Peer ' + connection.remoteAddress + ' disconnected.');
+  });
+});
+```
