根据文件类型添加自定义标题 [英] Add custom header based on file type

问题描述

我们正在尝试为 IIS 7.5 中的站点地图文件添加自定义标头 (X-Robots-Tag).但是，IIS 似乎不支持基于文件类型或通配符(仅子文件夹)的自定义标头.

We are trying to add a custom header (X-Robots-Tag) for sitemap files in IIS 7.5. However, it does not appear that IIS supports custom headers based on a file type or wildcard (only subfolders).

我们可以通过 Web.config 为 *.xml.gz 文件添加自定义标头吗?

Can we add a custom header for only *.xml.gz files via Web.config?

我们希望避免通过代码或在我们的负载均衡器上进行自定义.

We would like to avoid making the customization via code or on our load balancer.

推荐答案

您可以使用 IIS UrlRewrite 模块 并添加自定义出站规则以配置自定义标头.以下是您可能想要使用的示例规则:

You can use the IIS UrlRewrite module and add a custom outbound rule to configure the custom header. Here is a sample rule you may want to use:

  <system.webServer>
    <rewrite>
      <outboundRules>
        <rule name="Set custom HTTP response header">
          <match serverVariable="RESPONSE_X_Robots_Tag" pattern=".*" />
          <conditions>
            <add input="{REQUEST_URI}" pattern=".xml.gz$" />
          </conditions>
          <action type="Rewrite" value="The value you need for this header"/>
        </rule>
      </outboundRules>
    </rewrite>
  </system.webServer>
