Go 1.6 and HTTP/2 @nathany 

It Just Works* 

Server err := http.ListenAndServeTLS(":443", "cert.pem", "key.pem", nil) 

Client response, err := http.Get("https:// http2.golang.org/reqinfo") 

Issue #14391 • http.Client doesn't support http2 by default 

Issue #14275 • net/http: Transport's automatic http2 too aggressive

Configure Transport transport := &http.Transport{}
 err := http2.ConfigureTransport(transport)
 if err != nil {
 log.Fatal(err)
 }
 client := &http.Client{Transport: transport}
 
 response, err := client.Get("https:// http2.golang.org/reqinfo")
