title: socketio-jwt disconnect expired tokens
body: <p>I am able to authenticate using socketio-jwt and everything is working great. The problem I'm running into is if I set an expiration to a minimum time and let it expire I can continue to emit and receive messages on the connection. As long as I don't refresh the page the connection persists. Once I refresh the connection is disconnected and I am required to reconnect. Is it possible to have the server check for expired tokens and disconnect the connection?</p>
