Fiddler 2.1

Fiddler2 2.1.6.2 is a Web Debugging Proxy that logs all the traffic between your PC and Internet.
Fiddler allows you to inspect all HTTP(S) traffic, set breakpoints, and manage incoming or outgoing data. It includes an event-based scripting subsystem, and can be extended using any .NET language.

Fiddler can debug traffic from virtually any application, including Internet Explorer, Mozilla Firefox, Opera, and more.

The first thing that the program does when you finish installing it is going to the author´s site, and offering you to see an introductory video. In the background, it will check for updates of the program.

You will notice a new icon in your IE toolbar, that lets you start Fiddler. If the icon isn´t there, you can add it right-clicking in your IE toolbar and clicking over Customize. You can also start Fiddler using the Fiddler icon in your START | Programs menu, or you can type fiddler in Start | Run or SlickRun.

Fiddler will then show a screen with a list of your active HTTPS connections on the left, and their details on the right.
