I am studying swift source code.

My problem is: 1) What are the roles of class AccountController defined in swift / proxy / controllers / account.py and class AccountController defined in swift / account / server.py 2) How these two classes differ from each other and 3) How these two class interact with each other i.e. According to my understanding, when a user make a request, __call__() function defined in Application class in swift / proxy /server.py is executed, which ,in turn, calls handle_request() function which sends the control to the swift / proxy / controllers

Now, I can't understand through which function call will the control go to account server

Please help me in this regard
