	// By default, if the gRPC stream cannot be established, or if it is closed

	// response headers have not yet been delivered, then it will return a 500
	// error downstream. If they have been delivered, then instead the HTTP stream to the
	// downstream client will be reset.

Enterprise-only: Configuration for Envoy's [External Processing Filter](https://www.envoyproxy.io/docs/envoy/latest/configuration/http/http_filters/ext_proc_filter). The External Processing filter allows for calling out to an external gRPC service at a specified point within a HTTP filter chain. The external service may access and modify various parts of the request or response, and may terminate processing. Envoy's External Processing Filter is considered a work in progress and has an unknown security posture. Users should take care to understand the risks of using this extension before proceeding.
