The Auto Responder is one of the most powerful features of Fiddler Everywhere. It enables you to create rules that will automatically trigger in response to requests. The functionality provides means to easily and quickly test changes to web code without updating the production server, to reproduce previously captured bugs (in SAZ files), or to run website demos while being entirely offline.
Click the Auto Responder button
The two main tabs (Rule Editor and Queue Rules Viewer) of Auto Responder are shown
The Rule Editor tab allows you to create new rules and edit existing ones. See details on how to use the editor in the Rule Editor article
The Queue Rules Viewer list the currently used rules and provides additional control over them. The tab also exposes options to import/export rules files (FARX), to change the priority of the rules (of execution) and to entirely enable/disable the Auto Responder or specific rules. See details on how to use the editor in the Queue Rules Viewer article
You need to enable Live Traffic Capturing to be able to apply auto responder rules.
