Beschreibung

In the GRPC HTTP1 Reverse Bridge, there is currently no support to encode custom trailers in the GrpcWeb responses, that will be translated back to GRPC Response trailers. Currently, it seems that just the grpc-status is auto-inferred using the HTTP response code.

Is this something that can be added?

Here is the code for the grpc http1 reverse bridge: https://github.com/envoyproxy/envoy/tree/5248a4fb7d4c2a3d1fa151f944d3a63f6b7a06cf/source/extensions/filters/http/grpc_http1_reverse_bridge
