Hi MAbbas 

I also did a bit of reading on this subject, this is my opinion:
When proxying the HTTP/2 protocol, the same connection to a pool member can be used for multiple requests coming from multiple clients at the same time.
Very much similiar to OneConnect in HTTP/1.1. Sending pings from a pariticular client over a reverse proxy would be somewhat inconsistent with whole idea of multiplexing.

From my understanding gRPC keepalive is ment for peer-to-peer but not for proxied connections. If there is a requirement that clients keep a connection with the backend, TCP keepalive might be an option.
Or extending the the TCP timeout value.
