    25   * A HTTP server which serves Web Socket requests at:

    27   * https://localhost:8081/websocket
    28   *
    29   * Open your browser at https://localhost:8081/, 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:
