Hi Asyn,
This is a fun tool when you are interested in the inner workings of the HTTP Protocol or you want to debug certain issues.
Downloadable for free from: -http://www.cyberspyder.com/download/setupWebBug.exe File MD5:7ab4d40abcab2fcc1fd3ed105ca957b9
I use it alongside idserve.exe a free tool from Gibson Research together with Wireshark, Fiddler and snort for Windows,
because I like to know what is going over my wires or going on under the hood of my browser,
