Fiddler helps you analyse HTTP traffic

 

4 Guys From Rolla.com have published a helpful article on Microsoft's free HTTP traffic debugger "Fiddler" Troubleshooting Website Problems by Examining the HTTP Traffic.

You can download the latest version here.

Hints:

1. Fiddler works fine in IE, but is hardwired to ignore traffic on localhost or 127.0.0.1
   
   You can debug local site traffic by using the machine name as in http://MyDevPC:8081/
   
2. If you want to use Fiddler in Firefox (instead of Firebug) ,  Steve Smith shows how to do it here: Fiddler for Firefox.
   Basically you change Firefox to use Fiddler as a proxy.
