RequestHandler which is subclassed to create web applications, and various supporting classes). • Client- and server-side implementions of HTTP (HTTPServer and AsyncHTTPClient). • An asynchronous networking library protocols. The Tornado web framework and HTTP server together offer a full-stack alternative to WSGI. While it is possible to use the Tornado HTTP server as a container for other WSGI frameworks (WSGIContainer) framework and HTTP server together. 6.1.2 Asynchronous and non-Blocking I/O Real-time web features require a long-lived mostly-idle connection per user. In a traditional synchronous web server, this implies
