Question

我使用jQuery $.ajax调用来获取mvc3中的局部视图。同时我使用sessionfilter来检查会话超时。一旦会话超时，它将返回登录页面，但登录页面将显示在部分页面div中，而不是重定向到整个页面。我在global.ascx页面上尝试了下面的代码来修复它，但是它没有用。它会引发以下错误：

public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
   filterContext.HttpContext.Response.Clear();
   filterContext.HttpContext.Response.Write("**custom error message**");
   filterContext.HttpContext.Response.StatusCode = 401;
   filterContext.HttpContext.Response.End();
}

例外如下

您需要从操作过滤器或控制器执行重定向，而不是直接写入响应。这样可以避免您看到的页面布局问题。

在MCV3中发送HTTP标头后无法重定向
