To start the web server simply execute your script. Note the way the web server is started. The socketio.run() function encapsulates the start up of the web server and replaces the app.run() standard Flask development server start up. When the application is in debug mode the Werkzeug development server is still used and configured websocket_timeout is the timeout in seconds, used when receiving or sending data over the connection.
