How To Use Fiddler To Troubleshoot HTTP/HTTPS Issues

Fiddler is a very effective tool when it comes to troubleshooting HTTP & HTTPS issues… It’s basically a local proxy that intercepts all HTTP/HTTPS traffic either from all applications or just the application you configure it to… Fiddler configures itself as a local proxy on port 8888, processes traffic from the client application and then forwards it to the web server so it behaves like any proxy server except that it displays all information in the client application & allows for on the fly HTTPS decryption without the need for server certificate to decrypt traffic.
