How does one inspect the HTTP traffic in Adobe Air? Obviously because it's running outside of a browser you can't use firebug ...
I've tried this: ServiceCapture
but it doesn't work either... (nothing shows up in the log). I also don't really want to pay for a program.
Any ideas?
Wireshark will do that - it works at the network level, so it will work with any web technology.
The most important thing to know about is the right-click "Follow TCP/IP stream" command, which will show you your app's HTTP conversation.
