Question

http://localhost:54321/foo/bar等不正确的网址以及HttpNotFound()等错误在我的localhost中处理没有问题。部署到IIS 7.5后，它会在上述两种方案中返回空白页。我已经看到其他人有这个问题Here（这是Moulde的评论，有几个赞成票）。代码：

的Web.Config

<system.web>
  <customErrors mode="Off" redirectMode="ResponseRedirect">
    <error statusCode="404" redirect="~/Error/NotFound"/>
  </customErrors>
</system.web>
<httpErrors errorMode="Custom" existingResponse="Replace">
  <remove statusCode="404" />
  <error statusCode="404" responseMode="ExecuteURL" path="/Error/NotFound"/>
  <remove statusCode="500" />
  <error statusCode="500" responseMode="ExecuteURL" path="/Error/Error"/>
</httpErrors>

ErrorController

public class ErrorController : Controller
{
    public ActionResult NotFound() {
        Response.StatusCode = 404;
        Response.TrySkipIisCustomErrors = true;
        return View();
    }
}

RouteConfig

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

        routes.MapRoute(
            "Error - 500",
            "Error",
            new { controller = "Error", action = "Error" }
            );
        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );

NOTFOUND

<h2>404 Not Found</h2>
<div class="alert alert-info">
    <p><strong>Whoops...</strong></p>
    <p>The resource you were looking for doesn't exist</p>
</div>

服务器运行Windows Server 2008 R2。当我转到... / foo / bar或某个操作返回HttpNotFound()时，它会返回一个空白页面。任何的想法？

主/测试

public class HomeController: Controller{
    // ...
    public ActionResult Test(){
        return HttpNotFound();
    }
}

更新当我转到服务器上的/Error/NotFound时，它返回一个空白页面以及404.与Fiddler的回复：

HTTP/1.1 404 Not Found
Cache-Control: private
Content-Type: text/html; charset=utf-8
Server: Microsoft-IIS/7.5

Content-Length: 5434

更新2： 如果我离开existingResponse="Replace"，我可以在服务器上打开Error / NotFound。但仍然在MyServer/MyProject/foo/bar

上有空白页面

Answer 1

在我的情况下，原因是在IIS中 - 网页设置 - 请求过滤 - SQL注入过滤器...

如果url或查询字符串包含;，则响应以状态404.19结束 - 通过过滤规则拒绝。然后显示空白页面。 IIS重定向到此http://server.com/Error404.aspx?404;http://server.com/missingURL之类的自定义错误，而char ;是请求筛选器因SQL注入而终止您的请求的原因。

部署到IIS 7.5后空白的自定义404页面
