Hi Oleg, Thank you for your reply.
My simple use case is I want to control on which channel / protocol (HTTP 1.x or HTTP 2) the requests should use using async httpclient api implementation irrespective of backend server enablement of that respective protocol. Is there a way to achieve this usecase using same connection pool manager / single httpclient object?
