Pragya,

 my understanding of your question:

 Both of the controller is to handle the common HTTP REST request such as
 GET,PUT,POST,DELETE etc. The first controller is the entry point of
 proxy-server to handle the client requests which is exposed as Swift API
 externally. But the second controller is the entry point of account-server
 and won't be directly accessible by client. It will be invoked by the
 proxy server internally via HTTP RESTful interface to provide the specific
 account operations.

 Subject: problem in understanding interaction between swift proxy and
 other servers through swift source code

 Hello,

 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
 from proxy server to other (account/container/object)  server

 Please help me in this regard
