What is Fiddler?
Fiddler is a Web Debugging Proxy which logs all HTTP(S) traffic between your computer and the Internet. Fiddler allows you to inspect all HTTP(S) traffic, set breakpoints, and "fiddle" with incoming or outgoing data. Fiddler includes a powerful event-based scripting subsystem, and can be extended using any .NET language.
Fiddler captures HTTP and HTTPS traffic and logs it for the user to review (the latter by implementing man-in-the-middle interception using self-signed certificates).
Fiddler is freeware and can debug traffic from virtually any application, including Internet Explorer, Mozilla Firefox, Opera, and thousands more.







Comments and Reviews
I use fiddler more than Firebug and Wireshark because:
Firebug only works in Firefox and I do most of my work in Chrome. Also, Firebug is a Firefox extension so it can be a little clumsy at times.
Wireshark is often overkill when you want to debug http traffic. With Fiddler it's easier to see the http sent and the response with just a click. With Wireshark, the process to recompose the packets and uncompress them is not as easy.
Fiddler can do https with just one click. With Fiddler you spy on encrypted traffic and there's nothing special to install.

Since Eric Lawrence handed it to that Telerik company, this gem is now literally useless malware.
