What is Fiddler
It's a desktop app. Fiddler acts as a proxy, it runs on your Windows (or Mac or Linux) desktop and captures traffic going between your browser and a remote website so that you can see what is going on. I remember trying it out a couple times at different jobs but nothing struck me as truly great about it.
You can do pretty much the same thing with Wireshark, I think. Fiddler is just tuned for web whereas Wireshark is generic network data capture.
I got as far as putting mitmproxy on a Linux box and pointing my browser at it, but I can't remember why I did that. I just remember that it worked. See docker/mitmproxy on cc-testmaps.
HTTP headers
I need to see them, but they are visible in Chrome.
- F12
- Network tab
- Reload the page, watch all the network activity
- Pick a line in the left pane
- Switch from Preview to Headers in the right pane, there you go.
