I'll remember that next time. I been using fiddler to see websites http traffic which is helpful. But my programs http traffic doesn't show up there.. So ill try wireshark next time.
I think this might not be possible for SSL/TLS traffic, without some kind of MITM.
It is possible with SSL/TLS traffice: you need to supply private key to WireShark, so it will be able to decode conversation.
Most dev 'MITM' proxy tools have a way to inspect HTTPS by creating a new key and adding it to your systems trust.
Charles has a fairly neat way of making it all work.
