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

我正在构建一个包含自定义错误页面的新站点.我已经设置了我的web.config,并设置了所有页面.

当我在本地运行时,强制错误(找不到页面很容易),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>

我做错了吗？它与Windows Server 2008 R2有何不同？

编辑:我发现问题,这是web.config文件中的附加信息,如下所示:

默认情况下,IIS7拦截HTTP状态代码,例如由管道上的应用程序生成的4xx和5xx.

您可以告诉IIS只传递现有响应,而不用其自己的错误页面替换它:

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