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.


Solution

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: https://www.telerik.com/download/fiddler

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.
