Tornado [http://www.tornadoweb.org] is a Python web framework and asynchronous networking library, originally developed at FriendFeed [http://friendfeed.com]. By using non-blocking network I/O, Tornado Tornado can scale to tens of thousands of open connections, making it ideal for long polling [http://en.wikipedia.org/wiki/Push_technology#Long_polling], WebSockets [http://en.wikipedia.org/wiki/WebSocket] Tornado web application Templates and UI Authentication and security Running and deploying Web framework tornado.web — RequestHandler and Application classes tornado.template — Flexible output generation
