curl already re-uses the connection on its own and by default, no need to do anything. Try this for a simple example:

    $ curl -v --http2 https://nghttp2.org/ https://nghttp2.org/

If the server however closes the connection after the first request or otherwise denies a connection re-use, then it will of course create a new connection for the second transfer.
