Is it possible to enable http2 and have specific TLS configuration?

[Moshe Litvin]

The code in net/http/transport.go (onceSetNextProtoDefaults) contain:

 if t.TLSClientConfig != nil || t.Dial != nil || t.DialTLS != nil {
 // Be conservative and don't automatically enable
 // http2 if they've specified a custom TLS config or
 // custom dialers. Let them opt-in themselves via
 // http2.ConfigureTransport so we don't surprise them
 // by modifying their tls.Config. Issue 14275.
 return
 }

Stating that if you did something non-standard in the dialer or TLS you don't get http2 by default.

But the suggested opt-in methods does not exist (was replace by the non-public http2ConfigureTransport.

The net/http documentation only specify opting out, but is there a way to opt-in?

You have to depend on golang.org/x/net/http2 to opt in
