Python:friendfeed's Tornado Web Server__python

The code is very simple, less than 5k lines. But the idea is good, changed to non-blocking after the efficiency is able to improve a lot, especially considering that the modern web app all need to communicate with other
HTTP server, blocking the price is too great.

Tornado is a open source version of the scalable, non-blocking Web server and tools, power FriendFeed. The FriendFeed application is written using a web framework this looks a bit like web.py or Google's WebApp, but with Addi tional tools and optimizations to take advantage of the underlying non-blocking.
The framework is distinct from most mainstream Web server frameworks (and certainly most Python frameworks) because it is non-blocking and reasonably fast. Because it is non-blocking and uses epoll, it can handle thousands of simultaneous standing, connections which it are Ideal for real-time Web services. We built the Web server specifically to handle FriendFeed ' s real-time features-every active user of FriendFeed maintains An open connection to the FriendFeed servers. (For further information on scaling servers to support thousands of clients, which is the c10k problem.)
