(a) In nonpersistent HTTP (version 1.0), each client/server interaction involves setting up a TCP connection, carrying out the HTTP exchange, and closing the TCP connection. Let T be the time that elapse from when a packet is sent from client to server to when the response is received. Find the rate at which HTTP exchanges can be made using nonpersistent HTTP.

(b) In persistent HTTP (version 1.1), the TCP connection is kept alive. Find the rate at which HTTP exchanges can be made if the client cannot send an additional request until it receives a response for each request.

(c) Repeat part (b) if the client is allowed to pipeline requests, that is, doesn't have to wait for a response before sending a new request.
