title: Is it possible to make both TCP and UDP connections between two pieces of software
body: <p>I'm currently developping a highly responsive game in python using client-server model. The speed of the data exchanges between the client and the server needs to be very fast.</p>
  
  <p>Is it possible to make both, udp and tcp connections ? Udp would be used only during the game. And Tcp will be used for more reliability-needed messages like connection, name changes, chat,...
  Is it also a good way of thinking ? Or should i use only UDP ? </p>
