Envoy System Rules

The Envoy System includes the following System rules.

  • body: is a string that represents the response body data sent to the downstream client when a request is denied.
  • response_headers_to_add: is an object whose keys are strings and values are strings. It defines the HTTP response headers to be sent to the downstream client when a request is allowed.
  • request_headers_to_remove: is an array of strings that describes the HTTP headers to remove from the original request before dispatching it to the upstream when a request is allowed.
  • custom: (object) arbitrary extra data sent with the decision, for example, setting custom message data.
