Trying to inspect the header information being posted from my app but fiddler doesn't seem to pick anything up.
I am also using a web service in my app and when I invoke some of the APIs I can see these requests in Fiddler, however, when doing custom requests using Indy 10 nothing seems to be picked up.
Does Indy use WinInet? If not, that's the problem. Fiddler2 inserts itself as a proxy in your internet settings, but programs like SoapUI that use their own communication stack don't use WinInet, and therefore don't (auto-magically) pass through Fiddler2. So you may need to mess with proxy settings.
