刚打开握手后，websocket断开连接

Question

我想保持websocket连接活着。
我使用RFC 6455协议作为websocket协议 我通过Firefox 13和Chrome 20进行了测试。

=== WEB SOCKET CLIENT ===

GET / HTTP/1.1
Host: #.#.#.#:#
User-Agent: Mozilla/5.0 (Windows NT 5.1; rv:13.0) Gecko/20100101 Firefox/13.0.1
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: ko-kr,ko;q=0.8,en-us;q=0.5,en;q=0.3
Accept-Encoding: gzip, deflate
Connection: keep-alive, Upgrade
Sec-WebSocket-Version: 13
Origin: http://its.secret.com
Sec-WebSocket-Key: TbJqTlFtGocvRvk/9stMhg==
Pragma: no-cache
Cache-Control: no-cache
Upgrade: websocket

=== WEB SOCKET SERVER ===

HTTP/1.1 101 WebSocket Protocol Handshake
Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Accept: outIACgIETcILj0NjzA0MhwP7uc=

此websocket协议中的换行符为CR / LF。

下一个是websocket客户端源的一部分。

var host = "ws://#.#.#.#:#";
try {
    Rsocket = new WebSocket(host);
    Rsocket.onopen = function(msg) {
        alert("Welcome - status " + this.readyState);
    };
    Rsocket.onmessage = function(msg) {...
    };
    Rsocket.onclose = function(msg) {
        alert("Disconnected - status " + this.readyState);
    };
}
catch (ex) {
    log(ex);
}​

首先，成功警报出现在Web浏览器中 按OK后，会出现断开连接警告。

虽然出现成功警报时按OK，但我希望不显示断开警报。
