Indeed, but it's hardly a secret that you can use "sniffer" programs to read along with all the data that is senc accross your network.
However, if you want to make things "easy" ...
In PERL there is a function to let you use sockets.
Using that you can create a simple program that listens on port 80 (or any other port) and have it echo all incomint data. I use that to read headers some time ago.
Agreed, it's not the simplest solution, but it's very effective.
