net/http: Response.Write ignores Proto field and always uses HTTP as protocol specifier

[brutella]

I use http.Response to create packets

resp := new(http.Response)
resp.Status = "200 OK"
resp.StatusCode = http.StatusOK
resp.ProtoMajor = 1
resp.ProtoMinor = 0
resp.Proto = "EVENT/1.0"

I set the Proto field, but at the end the written bytes still contain HTTP/1.0 200 OK because that's hardcoded in response.go

Sorry, it's true that the net/http package is an HTTP package and assumes that the thing it's speaking is HTTP.

If you want to speak a different protocol, you'll need to use or write a different package.
