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

The first call to listen will create a server waiting for incoming connections on the specified port (2000) in this case. The same function may PipeServer(active) Note that the return type of the last invocation is different. This is because this server does not listen on TCP, but rather on a named pipe (Windows) or UNIX domain socket. Also note that
