Fiddler – Web Debugging Proxy For HTTP(S)

Check For Vulnerabilities with Acunetix

Recently I posted about Charles Web Debugging Proxy and quite a few people mentioned they had been using 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.
