ASP.NET登录页面重定向问题

我正在构建一个托管在ASP.NET Web App上的silverlight应用程序. / IIS7 /启用SSL的网站.
为了安全起见,我将Silverlight页面放在ASP.NET Web应用程序的Members文件夹中,并禁止匿名用户访问.(参见下面的web.config)

当用户尝试访问Members文件夹下的页面时,它们会被重定向到https://www.ssldemo.com/authenticationtest/login.aspx.(请参阅下面的web.config)
(我已将www.ssldemo.com映射到127.0.0.1).
为了安全起见,我在login.aspx中切换到HTTPS,并在验证后返回HTTP.
下面是login.aspx.cs的代码.

protected void Page_Load(object sender,EventArgs e)
    {
        LoginControl.LoggedIn += new EventHandler(LoginControl_LoggedIn);
    }

    void LoginControl_LoggedIn(object sender,EventArgs e)
    {
        //for going to ReturnURL & switching back to HTTP
        string serverName = HttpUtility.UrlEncode(Request.ServerVariables["SERVER_NAME"]);
        string returnURL = Request["ReturnURL"];
        Response.Redirect(ResolveClientUrl("http://" + serverName + returnURL)); 
    }

问题是,当我将另一个应用程序部署到http://www.ssldemo.com/authenticationtest/members/AnotherApplication/时
并打开http://www.ssldemo.com/authenticationtest/members/AnotherApplication/default.aspx,
用户被重定向到https://www.ssldemo.com/authenticationtest/login.aspx?ReturnUrl=%2fauthenticationtest%2fmembers%2fanotherapplication%2fdefault.aspx.
但即使我在登录页面输入正确的凭据,我也会被重定向到同一个登录页面,而不是ReturnUrl.当我看着提琴手时,它说“302物体移到了这里.”

谢谢你的阅读！任何输入将非常感激.
