// Server capacity is limited and is intended to handle only a small number of
// simultaneous connections (e.g. for communicating between applications on localhost).
// To test the HTTP server follow these steps :
// 1- Build and run this demo.
// 2- Click on the Start button.
// 3- Open your web browser and visit this address http://127.0.0.1:8099
// 4- You should see some connection details in the server log and a "Hellow world" text in your web browser.
// To test the websockets server follow these steps :
// 1- Build and run this demo.
// 2- Click on the "Start" button.
// 3- Open your web browser and visit this address https://www.websocket.org/echo.html
// 4- Type this in the "Location" field ws://127.0.0.1:8099
// 5- Click the "Connect" button.
// 6- Click the "Send" button.
// 7- You should see some connection details in the server log and the default text message "Rock it with HTML5 WebSocket"
