Fiddler HTTP Debugger - Fiddler

Fiddler HTTP Debugger - Fiddler: "Introducing Fiddler
What is Fiddler?
Fiddler is a HTTP Debugging Proxy which logs all HTTP traffic between your computer and the Internet. Fiddler allows you to watch HTTP Traffic, set breakpoints, and 'fiddle' with incoming or outgoing data. Fiddler is designed to be much simpler than using NetMon or Achilles."

Very cool... I hate using NetMon for HTTP debugging...
