无法使用Google Chrome浏览器内嵌框架和Windows身份验证注销

我有一个使用Windows身份验证的MVC 4应用程序。我目前的挑战是我需要为用户提供注销按钮。我可以直接在Chrome中实现这一点,但是当我将谷歌Chrome框架(GCF)添加到组合中时,我似乎有问题。

我正在使用IE9和GCF。

当我尝试发送AJAX请求时,这就是GCF网络跟踪告诉我的内容:

请求:

GET http://103581:107674@linkToMySite/LogOff401?_=1369312905224 HTTP/1.1
Accept: */*
Referer: http://LinkToMySite
X-Requested-With: XMLHttpRequest
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.93 Safari/537.36
Authorization: user:pass

不幸的是,响应失败了。 Chrome开发者工具会把它拿起来,但我认为IE正在阻止请求离开,因为Fiddler没有看到它。我很茫然,并且已经对此进行了多次故障排除,不确定这是否应该向Google报告为错误。

这是客户端注销代码(来自此处http://trac-hacks.org/wiki/TrueHttpLogoutPatch的改编):

function LogMeOut(url) {
    try {
        document.execCommand("ClearAuthenticationCache");
        SendAJAXLogout(url);
    }
    catch(err){
        try {
            SendAJAXLogout(url);
        } catch(err) {
            log("Unable to log this user out.");
        }
    }
    window.location.href = url;
}

function SendAJAXLogout(url) {
    $.ajax(url, {
        username: GetRandomNumber(10000, 99999),
        password: GetRandomNumber(10000, 99999),
        beforeSend: function (req) {
            req.setRequestHeader('Authorization', "user:pass");
        },
        cache: false,

        error: function (jqXHR, textStatus, errorThrown) {
            //alert("Error: " + textStatus);
            log("I'm logged out now");
        }
    });
}

这是我在其他地方找到的服务器端操作方法,但找不到链接(我没写这个):

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult LogOff401(string id)
{
    // if we've been passed HTTP authorisation
    string httpAuth = this.Request.Headers["Authorization"];
    if (!string.IsNullOrEmpty(httpAuth) &&
        httpAuth.StartsWith("basic", StringComparison.OrdinalIgnoreCase))
    {
        // build the string we expect - don't allow regular users to pass
        byte[] enc = Encoding.UTF8.GetBytes(id + ':' + id);
        string expected = "basic " + Convert.ToBase64String(enc);

        if (string.Equals(httpAuth, expected, StringComparison.OrdinalIgnoreCase))
        {
            return Content("You are logged out.");
        }
    }

    // return a request for an HTTP basic auth token, this will cause XmlHttp to pass the new header
    this.Response.StatusCode = 401;
    this.Response.StatusDescription = "Unauthorized";
    this.Response.AppendHeader("WWW-Authenticate", "basic realm=\"My Realm\"");

    return Content("Force AJAX component to sent header");
}
