Golang: How to terminate/abort/cancel inbound http request without response?

From server side I need to terminate/abort request without any response to client like nginx's 444.

From client side it should look like connection reset by peer.

I've spent a couple hours and only accidentally find http.Hijacker which allows to get access to net connection from http.ResponseWriter:

h := func(w http.ResponseWriter, r *http.Request) {
    if wr, ok := w.(http.Hijacker); ok {
        conn, _, err := wr.Hijack()
        if err != nil {
           fmt.Fprint(w, err)
        }
        conn.Close()
    }
}

Terminating connection may be useful in some cases for saving CPU time and outbound traffic.
