Socket Workbench

Socket Workbench is the definitive tool for analysing socket communications that underlie the Internet and several types of inter-process communication. Configure Socket Workbench to be a socket client (like a web browser or e-mail client) or a socket server with ease. You can send data through a socket and analyse that data that has been received. Also, Socket Workbench has the unique "Pass Through Mode" which allows the interception of socket communications between a client and its server without packet sniffing.
