Use Fiddler to explore HTTP GZIP compression

Once you've installed Fiddler (see Fiddler helps you analyse HTTP traffic) it's worth looking at the data savings using GZIP compression.

The above URL uses GZIP and delivers 57,127 bytes using just 12,320 bytes.

Certainly worth exploring your WWW site.

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.
