Can you explain how it isn't quite right? I would like to correct the article if this is the case.
When I ran the code, the Go HTTP/2 package caused a panic with the message "http2: TLSConfig.CipherSuites is missing HTTP/2-required TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256".
I went source diving and found the following:
https://golang.org/src/net/http/h2_bundle.go?h=TLS_ECDHE_RSA...
It even has the helpful comment:
> If they already provided a CipherSuite list, return an error if it has a bad order or is missing ECDHE_RSA_WITH_AES_128_GCM_SHA256.
I cannot see how I would have achieved my aim without disabling HTTP/2.
The aim of the exercise was to get a perfect score using Go. I wasn't discussing HTTP/2 in general. I was referencing the Go standard library implementation.
As I say, if you still think it's not right, please let me know.
