25   * A HTTP server which serves Web Socket requests at:
26   *
27   * http://localhost:8080/websocket
28   *
29   * Open your browser at http://localhost:8080/, then the demo page will be loaded and a Web Socket connection will be
30   * made automatically.
31   *
32   * This server illustrates support for the different web socket specification versions and will work with:
