I was just catching up on my outstanding blogs to read and came across this great tool called fiddler.  So what it is fiddler? From the website

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.

Fiddler can be downloaded here. Thanks to Scott W for the link.
