DevExpress MVC：显示外部内容

Question

示例：

@Html.DevExpress().Splitter(
settings => {
    settings.Name = "MySplitter";
    settings.Height = 1000;
    settings.Panes.Add (pane => {
        pane.Name = "MyPane1";
        pane.ContentUrl = "The_URL";
        pane.ScrollBars = System.Web.UI.WebControls.ScrollBars.Auto;
    });
}).GetHtml()

我可以添加直接访问所需的身份验证（用户名，密码和（域））吗？
