Fiddling with Fiddler
Fiddler allows you to see request data such as:
1) HTTP Request headers
2) Request body
3) Response headers
4) Response body
It has options to see the raw data as is or to shown in user-friendly format. It automatically decrypts base 64 encoding and has support for gzip/deflate protocols as well.
One feature I really like is the cloning feature. This feature allows you to clone an existing logged request, make modifications to be and execute it as a browser would do. This can be very useful to debug and test request/response issues.
Fiddler supports IE, Firefox and Chrome. I haven’t tested it in Safari or Opera yet.
A must have for all web developers and network engineers.
