call forwarding/chaining in grpc

[Mayuresh Karandikar]

What is the best way to implement call forwarding/chaining using grpc. 

Example scenario: Client A wishes to call service in client C through server/client B. 

A -> B -> C.

I can implement both server and client in B and manually forward the call. Looking to see if there is a way to do this wihout intervention from application logic. Something that is supported at grpc stack level. 

Thanks

So B is just a proxy? Have you looked into using Envoy which supports gRPC?

I have made a "grpc proxy" example in Java, which I've shared a few times. Such things should be possible in most other languages, although the difficulty would vary.

What language is server/client B written in?
