What is the best way to find an http response that has a certain string of text in its response?

Question

I'm debugging a web app with lots of AJAX on a windows machine. I have Fiddler and Wireshark and I'm open to getting any other free software that can help.

I am looking for the http response (and its request) that contain a certain string in them. What is the best way to find it?

Answer 1

This task is utterly trivial in Fiddler. Cause the traffic to happen, then hit CTRL+F and type the string you're looking for.

If you want Fiddler to automatically mark any sessions that contain a given string, use the utilFindInResponse method.
