Traffic Policy Overview

What is Traffic Policy?​

The ngrok engine enables you to manage traffic consistently across your endpoints. It allows you to inspect, manipulate, and route traffic in a structured way.

Features​

Traffic Policy is composed of a few key components:

  • Phases: Defined points in the traffic lifecycle where you can apply logic.
  • Phase Rules: The set of conditions and actions applied during specific phases to filter, manipulate, or manage traffic.
  • Expressions: Conditions used in Phase Rules to determine when an action should be applied.
  • Actions: Logic that is triggered when a Phase Rule condition is met.
  • Interpolation: A way to dynamically evaluate variables and macros inside configuration values, such as URLs or headers.
