/**
 * A HTTP server which serves Web Socket requests at:
 * 
 * https://localhost:8081/websocket
 * 
 * Open your browser at https://localhost:8081/, then the demo page will be loaded and a Web Socket connection will be
 * made automatically.
 * 
 * This server illustrates support for the different web socket specification versions and will work with:
 * 
 * <ul>
 * <li>Safari 5+ (draft-ietf-hybi-thewebsocketprotocol-00)
 * <li>Chrome 6-13 (draft-ietf-hybi-thewebsocketprotocol-00)
 * <li>Chrome 14+ (draft-ietf-hybi-thewebsocketprotocol-10)
 * <li>Chrome 16+ (RFC 6455 aka draft-ietf-hybi-thewebsocketprotocol-17)
 * <li>Firefox 7+ (draft-ietf-hybi-thewebsocketprotocol-10)
 * </ul>
