Question

我使用以下代码将用户重定向到我的asp.net mvc4应用程序中的错误页面，并使用ELMAH将错误发送为电子邮件：

protected void Application_Error()
        {
            Exception lastException = Server.GetLastError();
            //add user specific details
            lastException.Data["MachineName"] = Environment.MachineName;
            lastException.Data["ClientIP"] = Request.UserHostAddress.ToString();
            if (Request.ServerVariables["REMOTE_HOST"] != null)
            {
                System.Net.IPHostEntry host = new System.Net.IPHostEntry();
                host = System.Net.Dns.GetHostEntry(Request.ServerVariables["REMOTE_HOST"]);
                lastException.Data["ClientMachineName"] = host.HostName;
            }

            IController errorController;

            HttpException httpException = lastException as HttpException;
            RouteData routeData = new RouteData();
            //Try catch the error, as NLog throws error in Release mode
            System.Diagnostics.EventLog _eventLog = new System.Diagnostics.EventLog("Application", Environment.MachineName, ConfigurationManager.AppSettings[Constants.EventLogSource]);
            _eventLog.WriteEntry(lastException.ToString(), System.Diagnostics.EventLogEntryType.Error);

            //Possible reason for null is the the server error may not be a proper http exception
            if (httpException == null)
            {
                //Call target Controller
                errorController = new ErrorController();
                routeData.Values.Add("controller","Error");
                routeData.Values.Add("action", "Index");
                Response.Clear();
            }
            else
            //It's an Http Exception, Let's handle it.   
            {
                switch (httpException.GetHttpCode())
                {
                    case 404:
                        //Page not found.
                        //Call target Controller
                        errorController = new UserController();
                        routeData.Values.Add("controller", "User");
                        routeData.Values.Add("action", "PageNotFound");
                        break;
                    case 302:
                        //Page Temporarily Moved
                        //Call target Controller
                        errorController = new UserController();
                        routeData.Values.Add("controller", "User");
                        routeData.Values.Add("action", "PageNotFound");
                        break;
                    case 500:
                        //Server error.
                        //Call target Controller
                        errorController = new ErrorController();
                        routeData.Values.Add("controller","Error");
                        routeData.Values.Add("action", "Index");
                        break;
                    //Here you can handle Views to other error codes.           
                    //I choose to redirect to Signin
                    default:
                        //Call target Controller
                        errorController = new ErrorController();
                        routeData.Values.Add("controller","Error");
                        routeData.Values.Add("action", "Index");
                        break;
                }
            }
            //Pass exception details to the target error View.  
            routeData.Values.Add("error", lastException);
            //Clear the error on server.  
            Server.ClearError();
            //Call target Controller and pass the routeData.  
            errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
        }

它在LOCAL中完美地返回错误，但是当从服务器（Windows Server 2008 R2，IIS 7.5）中，它在ELMAH发送的电子邮件中返回找不到页面错误。

本地错误:(这是完美的）

服务器错误:(这不正确）

有关此实施的错误的任何建议吗？
