I’ve just found very useful feature in Fiddler – comparing two sessions (HTTP request and response). Even more useful – the compare tool can be configured via registry settings:
To configure Fiddler to point to it:
- Close Fiddler.
- Run RegEdit
- Navigate to HKCU\Software\Microsoft\Fiddler2
- Add a new REG_SZ named CompareTool
- Set the new registry value to the path to your text comparison tool.
