IIS7 Web服务器自定义错误 - 在本地工作，但不会发布到生产 [英] IIS7 web server custom errors - works on local but not when published to production

问题描述

我正在建立一个含有自订错误网页的新网站。

I am building a new site with custom error pages. I have setup my web.config, and have all of my pages setup.

当我在本地运行，并强制错误（找不到页面是容易的）一切都很好。但是当我发布到我的Windows Server 2008 R2生产服务器，并输入一个坏的页面，它仍然需要我到默认IIS7错误页面。

When I run locally, and force errors (page not found is the easy one), it all works well. But when I publish to my Windows Server 2008 R2 production server, and enter a bad page, it still takes me to the default IIS7 error page.

这里是一个示例我的web.config（和我的页面都在那里）：

Here is a sample from my web.config (and my pages are all there):

<?xml version="1.0"?>

    <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>

我做错了什么简单吗？它是与Windows Server 2008 R2的区别吗？

Am I doing something simple incorrectly? Is it a difference with Windows Server 2008 R2?

编辑：我发现这个问题，这是web.config文件中的附加信息，如下所示： p>

I found the issue, which is additional information in the web.config file, to look like this:

推荐答案

默认情况下，IIS7拦截HTTP状态代码，如4xx和

By default IIS7 intercepts HTTP status codes such as 4xx and 5xx generated by applications further up the pipeline.

您可以告诉IIS只传递现有响应，而不用替换为自己的错误页面：

You can tell IIS to just pass through the existing response without replacing it with its own error page:

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