" Sente is a small client+server library that makes it easy to build reliable, high-performance realtime web applications with Clojure".

We need do two things to support Sente :

1. Set :websocket? true in the Ring request map of WebSocket handshake requests.
2. Implement the two interfaces and create a PR to Sente github source repository.

Because the first thing can not be done with current version 0.4.1 without additional request wrapper so we have to do it with the next version 0.4.2.
