Fiddler is great. Hadn't heard of NetRipper. Will take a look, thanks.

Also worth considering is Microsoft Message Analyzer, which used to be Network Monitor (NetMon). https://blogs.technet.microsoft.com/MessageAnalyzer/

Edit: I should add that this isn't an endorsement, just another option. I only included MMA as a side-note in my recent book. I focussed on Wireshark and Fiddler to keep things simple.
