转到Websocket服务器与Python高速公路客户端冲突

Question

I have been successfully writing a Go (server) websocket 'chat' application based in this example code

Both client and server work as expected.

When I have come to implement a client using Python's Autobahn I am running into trouble. it is based on this example

ws://localhost:8080/ws (which works in Chrome) yields an HTTP 1.0/400 from the server. ws://localhost:8080/ (does not work in Chrome) yields an HTTP 1.0/200 from the server (in both cases).

Scanning the source (I admit, I don't know the WS protocol) seems to imply that the server should be responding with a 101.

This is the output from Autobahn:

UPDATE: I have also tried against this sample Go code which is a very trivial echo server. This makes me even more suspicious of my Autobahn code.

UPDATE: Code, as requested:

package main

import (
    "net/http"
    "io"
    "code.google.com/p/go.net/websocket"
)

func EchoServer(ws *websocket.Conn) {
    io.Copy(ws, ws);
}

func main() {

    http.Handle("/ws", websocket.Handler(EchoServer));

    err := http.ListenAndServe(":8080", nil);
    if err != nil {
            panic("ListenAndServe: " + err.Error())
    }
}
