We introduced the Traffic Policy Module to simplify configuration across all ngrok platforms, whether it’s the cloud, API, SDKs, or Kubernetes. A Common Expression Language (CEL) variable is a simple yet powerful language for evaluating expressions designed for safety, performance, and ease of integration. CEL variables contain information extracted from incoming connections, providing details about requests and responses such as headers, method, URL, and more. These variables enable the creation of dynamic and powerful traffic filtering rules by adapting to varying conditions, making Traffic Policy documents more flexible and responsive. By using CEL variables, you can leverage information from requests and shape traffic for various scenarios with appropriate responses, enhancing the flexibility and control of your Traffic Policy documents.
