1 - Download the Fiddler 4 application and install it on the machine used to reproduce the problem (if you have not already). Go to http://www.telerik.com/download/fiddler
2 - Enable the option to decrypt HTTPS traffic: Tools -> Options -> Https -> select ‘decrypt HTTPS Traffic’ (you may be prompted to install the Fiddler certificate - make sure to select Yes)
Ensure this option is checked when collecting the trace as the data will have to be recollected if it is not.
3 - Restart the Fiddler program
(For browser-based apps)
(For non browser-based apps)
4b. Launch your client application
5 – Reproduce the problem and you should see https traffic showing up in the Fiddler window.
6 - Save the resulting session output as SAZ files (File -> Save -> All Sessions)
