Golang Server关闭客户端的连接：websocket

Question

i have a problem with my golang server in which i'm using websockets. The server opens the connection and the client could connect to it, but the problem is that when the server starts sending the data to the client, the client connection is closed after a small period of time. i suggest that the problem is with the server and not with the client because i tried to connect to the server with another web client, and it's the same issue. I didn't understand the cause ! Can someone help me?

server.go:

    func Echo(ws *websocket.Conn) {
    fmt.Println("Echoing")

         for {
        msg := MessageReceived{Name: "OrderCommand", Nbmsg: 3}

        if err := websocket.JSON.Send(ws, msg); err != nil {
            fmt.Println("Can't send")
            break
        }

    //os.Exit(0)
         }
}

func checkError(err error) {
    if err != nil {
        Log("Fatal error ", err.Error())
        os.Exit(1)
    }
}


func main() {

    http.HandleFunc("/save", saveHandler)
    http.Handle("/", websocket.Handler(Echo))
    err:= http.ListenAndServe(":8081", nil)
    checkError(err)

}

and client.go:

 import (
    "code.google.com/p/go.net/websocket"
    "fmt"
    "log"
)

func main() {
    origin := "http://localhost/"
    url := "ws://localhost:8081/echo"
    ws, err := websocket.Dial(url, "", origin)
    if err != nil {
        log.Fatal(err)
    }

    var msg = make([]byte, 512)
    var n int
    if n, err = ws.Read(msg); err != nil {
        log.Fatal(err)
    }
    fmt.Printf("Received: %s.
", msg[:n])
}

Why using ws.Read when you can use websocket.JSON.Receive to deserialize the message?

Here are the server: http://play.golang.org/p/NZ6VJ4daGm and the client: http://play.golang.org/p/rkJVKGhrGk (that I have changed to receive 10 messages before exiting).

The string "Can't send" will be printed by the server once the client closes the websocket connection.
