Fiddler is a great tool for capturing network traffic. I find it especially useful when I’m working with services. It sniffs out your network traffic and allows you to dig into every incoming or outgoing request. You can even create requests from inside the tool. So how does it work? Fiddler installs a proxy on your machine (default on port 8888). That proxy intercepts all network traffic going from and to the machine it’s installed on. That traffic gets displayed in the Fiddler UI. The proxy captures the traffic, sends it to the application and let the traffic itself pass to the original destination. This image shows the normal client – internet situation (top half) and the situation with Fiddler installed (bottom half).
