How to obtain the default HttpHandler in order to only influence keepalive settings

[OkkeHendriks]

Hello,

I want to enable HTTP/2 keep alive for a gRPC client. I believe that I should supply the relevant settings via the GrpcChannelOptions.HttpHandler property.

My question is, how should I construct a default HttpMessageHandler, which normally happens here.

I only want to influence the keepalive settings, the rest should be the gRPC defaults which are used internally.

Is there something I am missing here or should those default be exposed somehow?
