Description

The Rules tab is a powerful debugging functionality in Fiddler Everywhere. How can I use each of the predefined actions in the Actions drop-down and customize a rule?

The main idea behind the Rules tab is to provide a set of rules based on match rules and actions, which quickly mock a server response and behavior without the need to modify the server. Within seconds, you can execute many complex and different rules, and test your site against multiple scenarios.

All response modification actions are final. Final actions will immediately stop any other consecutive actions and rules from execution.

Using the Predefined Actions in Rule Builder

The Return Predefined Response action in the Rules Builder provides predefined options with descriptive names for the simulated response.

Example for using the predefined responses

The content of each predefined option is as follows:
