Using TCPMon to listen to HTTP Requests and Responses

Looks like TCPMon is not more supported by apache as I can see this message on its home page @ http://ws.apache.org/tcpmon: This project is no longer supported. Any information may be inaccurate or incomplete. Old archived releases are available from here. However we will see tcpmon here quickly as it is very easy to configure and use for simple http request/response scenarios.

Introduction to Wireshark – Basic Concept, Installation and First Data Capture

Wireshark is a free and open-source packet analyzer that captures data packets flowing over the network (wire) and presents them in an understandable form through its GUI. It is used for network troubleshooting, analysis, software and communications protocol development, and education. It runs on Linux, OS X, BSD, Solaris, some other Unix-like operating systems, and Microsoft Windows. There is also a terminal-based (non-GUI) version called TShark.
