ASP。NET MVC 404处理和IIS7 。

Good day!

美好的一天!

I use strategy to handle 404 errors like this: Error handling for ASP.NET MVC 2 and IIS 7.0 or this: How can I properly handle 404 in ASP.NET MVC?

我使用策略来处理404错误:ASP的错误处理。NET MVC 2和IIS 7.0或者这个:我如何在ASP中正确地处理404。净MVC吗?

In short: I handle 404 as exception in Global.asax without adding any routing rules, if the exception is 404 I render special controller\action with error message.

简而言之:我处理404作为全局异常。没有添加任何路由规则的asax，如果异常是404，我将呈现带有错误消息的特殊控制器\操作。

On IIS6 it works with ASP.NET wildcard mapping. On IIS7 in integrated mode I need to add the following to the Web.config (where /error/HttpError404 is my action with 404 page):

在IIS6上，它与ASP一起工作。净通配符映射。在IIS7的集成模式下，我需要在Web上添加以下内容。配置(where /error/HttpError404是我的操作，带有404页面):

    <httpErrors>
        <remove statusCode="403" subStatusCode="-1" />
        <remove statusCode="404" subStatusCode="-1" />
        <error statusCode="404" prefixLanguageFilePath="" path="/error/HttpError404" responseMode="ExecuteURL" />
        <error statusCode="403" prefixLanguageFilePath="" path="/error/HttpError403" responseMode="ExecuteURL" />
    </httpErrors>

Why? Routing works differently on IIS integrated mode and IIS6 wildcard mapping?

为什么?在IIS集成模式和IIS6通配符映射上，路由的工作方式不同?

Thanks in advance!

提前谢谢!

UPDATE: According to my tests it seems that my error handling works and my 404 action is rendered, but it seems that IIS sees 404 response code (which I set programmatically in my 404 action) and replace my page with default errors.

更新:根据我的测试，似乎我的错误处理和404操作都有效，但IIS似乎看到了404响应代码(我在404操作中以编程方式设置)，并将页面替换为默认错误。

When I set <httpErrors> I got two hits for 404 page: one from exception handling in Global.asax and one from IIS.

当我设置 时，我得到了404页面的两个点击:一个来自全局异常处理。asax和IIS中的一个。

Can this be the cause?

这是原因吗?

It seems I have fixed it by setting in Web.config:

好像是我在Web.config中设置的。

<httpErrors existingResponse="PassThrough" />
