Please provide the steps to reproduce as a Go program, not (just) a Unix command-line. (How did you configure the server on the Go side?)

(How did you configure the server on the Go side?)

Basic configurations like this can reproduce the issue

package main

import (
        "fmt"
        "net/http"
)

func main() {
        if err := http.ListenAndServe(":8001", http.HandlerFunc(handler)); err != nil {
                fmt.Println(err)
        }
}

func handler(w http.ResponseWriter, r *http.Request) {
        fmt.Fprint(w, "")
}

I'd never heard of 505. Seems fine.

/cc @neild

I think the ": unsupported protocol version" after "400 Bad Request" shouldn't be there.
since the response has body, it could be nice to provide Content-Length header for easy parsing(?)

Change https://golang.org/cl/261977 mentions this issue: net/http: return 505 status for rejected protocol version
