It has ready-made TCP, UDP, and other protocol servers. We can create a ForkingServer class inherited from TCPServer and ForkingMixIn.

Our server also needs to inherit from ForkingMixIn to handle clients asynchronously.

The ForkingServer class also needs to set up a request handler that dictates how to handle a client request. Here ...
