configuration - IIS7 Web 服务器自定义错误 - 适用于本地但不适用于发布到生产环境

Question

我正在构建一个带有自定义错误页面的新站点。我已经设置了我的 web.config，并设置了我的所有页面。

当我在本地运行并强制出错时(找不到页面是最简单的)，一切正常。但是当我发布到我的 Windows Server 2008 R2 生产服务器，并输入一个错误页面时，它仍然会将我带到默认的 IIS7 错误页面。

这是我的 web.config 中的一个示例(我的页面都在那里):

<?xml version="1.0"?>

        <compilation debug="true" targetFramework="4.0"/>
    <customErrors mode="On" defaultRedirect="~/ErrorGeneral">
      <error statusCode="400" redirect="~/ErrorBadRequest" />
      <error statusCode="401" redirect="~/ErrorUnathorized" />
      <error statusCode="402" redirect="~/ErrorPaymentRequired" />
      <error statusCode="403" redirect="~/ErrorForbidden" />
      <error statusCode="404" redirect="~/ErrorItemNotFound" />
      <error statusCode="405" redirect="~/ErrorMethodNotAllowed" />
      <error statusCode="406" redirect="~/ErrorNotAcceptable" />
      <error statusCode="412" redirect="~/ErrorPreconditionFailed" />
      <error statusCode="500" redirect="~/ErrorInternalServerError" />
      <error statusCode="501" redirect="~/ErrorNotImplemented" />
      <error statusCode="502" redirect="~/ErrorBadGateway" />
    </customErrors>
    </system.web>
</configuration>

我做错了一些简单的事情吗？与 Windows Server 2008 R2 有区别吗？

编辑:我发现问题是 web.config 文件中的附加信息，如下所示:

默认情况下，IIS7 拦截由应用程序生成的 HTTP 状态代码，例如 4xx 和 5xx，这些代码是在管道上进一步生成的。

您可以告诉 IIS 只传递现有的响应，而不用自己的错误页面替换它:

<configuration>
  <system.webServer>
    <httpErrors existingResponse="PassThrough" />
  </system.webServer>
</configuration>
