部署到IIS 7.5后的空白自定义404页 [英] Blank custom 404 page after deploying to IIS 7.5

问题描述

不正确的网址，如的http：//本地主机：54321 /富/栏和错误，如 HttpNotFound（）在我的本地主机没有问题的处理。部署到IIS 7.5后，对上述两个方案中返回一个空白页。我见过别人有这个问题，这里（这是一个从Moulde与几个upvotes注释）。在code：

Incorrect urls like http://localhost:54321/foo/bar and errors like HttpNotFound() are handled in my localhost without problems. After deploying to IIS 7.5, it return a blank page on both of the above scenarios. I've seen someone else had this problem Here(It was the comment from Moulde with several upvotes). The code:

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。当我去... /富/酒吧或一个动作返回 HttpNotFound（），它返回一个空白页。任何想法？

The server runs Windows Server 2008 R2. When I go to .../foo/bar or an action returns HttpNotFound(), it returns a blank page. Any idea?

首页/测试

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

更新：
当我去 /错误/ NOTFOUND 在服务器上，它返回一个空白页，以及与404与小提琴手的响应：

Update: When I go to /Error/NotFound on server, it returns a blank page as well with 404. The response with Fiddler:

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

更新2：
如果我参加 existingResponse =替换了，我可以在服务器上打开错误/ NOTFOUND。但仍然有空白页要播/ MyProject的/富/条

Update 2: If I take existingResponse="Replace" away, I can open Error/NotFound on the server. But still got blank page on MyServer/MyProject/foo/bar

推荐答案

在我的情况的原因是在IIS中 - 网络设置 - 请求过滤 - SQL注入过滤器...

In my case the reason was in IIS - web settings - Request Filtering - SQL injection filter...

如果URL或查询字符串包含; ，响应与状态404.19结束 - 被过滤规则拒绝。则显示空白页。 IIS重定向到自定义错误这样 http://server.com/ Error404.aspx 404; HTTP：？//server.com/missingURL 和焦; 就是为什么请求筛选结束你的，因为SQL注入的要求

If url or query string contains ;, response ends with status 404.19 - Denied by filtering rule. Then blank page is displayed. IIS redirect to custom error like this http://server.com/Error404.aspx?404;http://server.com/missingURL and the char ; is why Request Filter end your request because of SQL injection.
