This program helps you debug TCP/IP software. It allows you to see what communication is taking place between programs that use your proxy. For example you can use it to proxy your web traffic and see what your incoming and outgoing traffic looks like. You can also use it as a proxy for a known spyware program and see what it's sending to it's home server. You could use it to expose the structure of IRC chat traffic. The possibilities are limited only by your immagination!
