自定義錯誤只在本地顯示，但不在遠程服務器

Question

我爲我的ASP.NET MVC應用程序創建了自定義錯誤，出於某種原因它們只顯示在本地計算機上，但是當我在遠程服務器上部署應用程序時默認的IIS錯誤頁面出現（404和500），我想明白爲什麼會這樣。這裏是我的應用程序配置：

的web.config

<system.web> 
    ... 
     <customErrors mode="On" defaultRedirect="~/ServerError"> 
      <error statusCode="404" redirect="~/NotFound" /> 
     </customErrors> 
    ... 
</system.web> 

路由配置

public static void RegisterRoutes(RouteCollection routes) 
{ 
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); 

    routes.MapRoute(
     "Error - 404", 
     "NotFound", 
     new { controller = "Error", action = "NotFound" } 
    ); 

    routes.MapRoute(
     "Error - 500", 
     "ServerError", 
     new { controller = "Error", action = "ServerError" } 
    ); 

    routes.MapRoute(
     name: "Default", 
     url: "{controller}/{action}/{id}", 
     defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional } 
    ); 
} 

錯誤控制器：

public class ErrorController : Controller 
{ 
    [AllowAnonymous] 
    public ActionResult ServerError() 
    { 
     Response.StatusCode = (int)HttpStatusCode.InternalServerError; 

     return View(); 
    } 

    [AllowAnonymous] 
    public ActionResult NotFound() 
    { 
     Response.StatusCode = (int)HttpStatusCode.NotFound; 

     return View(); 
    } 
} 

的Global.asax

protected void Application_Error(object sender, EventArgs e) 
{ 
    Response.TrySkipIisCustomErrors = true; 
} 

本地計算機的IIS配置和遠程一個看起來相似，但也許我錯過了一些東西，我必須配置得當也。

感謝您的任何幫助。

這解決了這個問題：

public class ErrorController : Controller 
{ 
    [AllowAnonymous] 
    public ActionResult ServerError() 
    { 
     Response.StatusCode = (int)HttpStatusCode.InternalServerError; 

     Response.TrySkipIisCustomErrors = true; 

     return View(); 
    } 

    [AllowAnonymous] 
    public ActionResult NotFound() 
    { 
     Response.StatusCode = (int)HttpStatusCode.NotFound; 

     Response.TrySkipIisCustomErrors = true; 

     return View(); 
    } 
}
