Monitor HTTP/HTTPS Traffic On Your Workstation or Servers
Fiddler is Web Debugging Proxy which logs all the HTTP(S) traffic between your computer and the internet/other computers.
In many scenarios applications need to interact with each other by passing information back & forth between each other to ensure successful handshaking. In these scenarios debugging becomes a challenge and hence first isolating the issue to a particular application/server is very essential.
This is very useful tool especially while debugging such issues which involve identifying the exact query strings that are being passed to the remote computer/internet from your computer during the process of handshaking. This tool can help us in isolating the issue there by reducing the scope of analysis.
