Using ThreadingMixIn in your socket server applications
Perhaps you prefer writing a multi-threaded application over a process-based one due to any particular reason, for example, sharing the states of that application across threads, avoiding the complexity of inter-process communication, or something else. In such a situation, if you want to write an asynchronous network server using SocketServer library, you will need ThreadingMixIn.
Getting ready
By making a few minor changes to our previous recipe, you can get a working version of socket server using ThreadingMixIn.
How to do it...
As seen in the previous socket server based on ForkingMixIn, ThreadingMixIn socket server will follow the same coding pattern of an echo server except for a few things. First, our ThreadedTCPServer will inherit from TCPServer and TheadingMixIn. This multi-threaded version will launch a new thread when a client connects to it. Some more details can be found at http://docs.python.org/2/library/socketserver.html...
