27   * A HTTP server which serves Web Socket requests at:
28   *
29   * http://localhost:8080/websocket
30   *
31   * Open your browser at http://localhost:8080/, then the demo page will be loaded and a Web Socket connection will be
32   * made automatically.
33   *
34   * This server illustrates support for the different web socket specification versions and will work with:
