Interesting facts
Fiddler can also be used to modify ("fiddle with") HTTP traffic for troubleshooting purposes as it is being sent or received.[6] By default, traffic from Microsoft's WinINET HTTP(S) stack is automatically directed to the proxy at runtime, but any browser or Web application (and most mobile devices) can be configured to route its traffic through Fiddler.
