Is there an architecture diagram or doc some where that briefly describes how the system works especially in terms of the roles of the processes like traffic_manager and traffic_server and how they interact, communicate. How the threads get the request, who runs the event loop etc. Even a general block diagram would work for me. It will of great help in understanding the system. Thanks -- Pranav > -- leif > >
