Sniff, Sniff here and a fiddle there

I came across another cool tool the other day, we all love Regmon, Filemon as well as Netmon in support. Netmon is the hardcore tool that all network admins use to sniff those network packets to try and understand what data is being sent along the wire. So while debugging my customers Outlook Web Access/WebDav issues trying to understand whats going on in the background. I found fiddler.

Fiddler is written by a program manager in the Internet Explorer team and has been out for some time. Fiddler is a HTTP Debugging Proxy which logs all HTTP traffic between your computer and the Internet. Fiddler allows you to inspect all HTTP Traffic, set breakpoints, and "fiddle" with incoming or outgoing data. Its a lightweight version of Netmon which is easy to read and understand.

The tool is a Microsoft toy and you can pick it up from https://www.fiddlertool.com. Eric the developer has also written a good MSDN article on it.
