(Windows users: you can use the excellent and free Fiddler Web Debugger, but I won't be walking you through that today, sorry. The free version has the HTTP Proxy feature, which is the only bit we need grab that. I settled on PortSwigger's Burp Suite, a comprehensive HTTP security analysis tool. I came across several glowing references to Tuffcode's MacScoop HTTP Scoop during my research, but didn't really want to spend $15 on an app I was only going to use once. It's a bit like using an electron microscope when what you wanted was a magnifying glass. The grandaddy of all network traffic sniffers is Wireshark, but it's rather low-level and overpowered for quickly looking through HTTP traces. The first thing you need is an HTTP sniffer program.

If you find yourself in need of a similar solution - perhaps for iOS app development, reporting a bug or some other reason (or just plain hacker interest!) - then click through for step-by-step instructions on how to intercept and view your iOS web traffic from any Mac running on the same network. I managed to get it working after doing a little research. This is the sort of thing I used to do all the time when my day job was writing load testing scripts for big ecommerce sites, but the first time I'd had to do it on the Mac or from an iOS client. So, all I needed to do was figure out a way to see the traffic on the web service. However, like almost all network-aware iOS apps, this one was clearly using a web service to get data from the backend. I knew there was a much better chance of getting the bug fixed if I could a) prove it was a bug and b) show the devs exactly where the problem was, but I was hampered by the usual problem: iOS apps are a bit of a black box, and I couldn't see what it was doing internally. I was seeing intermittent issues with an iPhone app, Tapatalk, not working properly with a web forum hosted by a friend of mine. Image credit: Matrix Rain by docmiller on deviant art, CC BY-SA 3.0
