Enabling HTTPS capture through Fiddler

Tags: Features

Problem Definition

You are interested in capturing HTTPS traffic to/from PortalGuard and would like to know what program to use and how to perform this action.


Fiddler is a web browser proxy that can capture HTTP requests from your browser and the associated responses from any web servers. It can capture both clear-text (HTTP) as well as encrypted (HTTPS) traffic. You can download Fiddler from here:

Once you open Fiddler, it will automatically be collecting traces. If you have sites using SSL (i.e. HTTPS) you will also want to enable SSL capture with the following menu: Tools->Fiddler Options…

From there, click the “HTTPS” tab and tick/enable the following checkboxes:

  • Capture HTTPS CONNECTs
  • Decrypt HTTPS traffic
  • Ignore server certificate errors

Once the tracing has been captured by Fiddler, it should look something like this:

Once the issue is reproduced, use the menu item: File->Save->All Sessions… to save the traces to a compressed file that you can email.
