Showing Only Traffic from Specific Hosts

Similar to showing traffic only from localhost, there are scenarios where you would like to test and see traffic generated from a specific hostname.

With Fiddler Everywhere, you can easily create rules that limit the captured traffic so that you can see and concentrate only on the sessions that matter.

Creating a "Show Only Host Traffic" Rule

This example shows how to create a rule named "Show Only Host Traffic" that hides all captured traffic except for traffic generated from the specified host.

Create a "Show Only Host Traffic" rule that sets the following matching conditions and actions through the Rules Builder.

  1. Create a matching condition that uses the "When none of these conditions are met any number of times" pattern. This rule uses the negative statements to match and apply actions on anything but the desired targets.

  2. For the matching condition, match by a URL that uses a regular expression for addresses that contain and

  3. Create a Do Not Show action.

    The Do Not Show action is final. No other action or active rule placed lower in the rules queue will be executed.

This sample Fiddler rule hides all sessions except those containing or in their URLs.

Creating "Show Only Host Traffic" rule

Once the rule is created, enable the Rules tab, toggle the rule switch, and start capturing traffic.

Activating the "Show Only Host Traffic" rule

Download a ready-to-use "Show Only Host Traffic" rule as a FARX file, which you can import through the Rules toolbar.
