Build a grpc c++ client for receiving response from streaming server

[Prashant Shubham]

I am trying to build a `grpc` `rpc` which has stream on server side. 

The proto is like

    rpc xyz (abc) return (stream asd){}

How to build a C++ client to keep listening on the stream even after the `rpc` returns response once.

    std::unique_ptr<ClientReader<asd>> reader(stub_->xyz(&context, request));

    while (reader->Read(&reply)) {

        std::cout<<"Response got from server: " << reply.message() << " " << std::endl;

    }

I am able to get reply once but how to keep listening on the same channel even after the response come. I tried introducing `while()` but it closes after raising exception.

The grpc server is written in java.

If possible can you please share sudo code of java server? Also, is it grpc client to grpc server call or is there any proxy in between?
