Application_Error中捕获Global.asax +未知错误

Question

当我启动程序时，我会立即在日志文件中记录“文件不存在”错误。然后，我尝试创建一个没有任何母版页但仍然收到此错误的干净Web表单，奇怪的是，但对我来说可能是好的，它不执行重定向，就像捕获的常见异常一样。从记录的文件中，我无法从消息中分辨出任何内容。有人有线索吗？感谢。

 void Application_Error(object sender, EventArgs e)
        {
            // Code that runs when an unhandled error occurs       
            Exception objErr = Server.GetLastError().GetBaseException();
            log.Error(objErr.Message, objErr);
            Response.Redirect("~/error.aspx");
        }
