目前，我从Linux（阿帕奇）服务器迁移到Windows（IIS）。在Linux上我使用.htaccess文件来检查HTTP_REFERER值，以保证我们的文件只正在从我们的网站下载，而不是从其他网站链接：

I'm currently migrating from a Linux (Apache) server to Windows (IIS). On Linux I'm using a .htaccess file to check the HTTP_REFERER value, to ensure our files are only being loaded from our site, and not linked to from other sites:

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^http(s)?://(www.)?foo.com [NC]
RewriteRule .(dcr)$ - [NC,F,L]

我怎样才能做到这一点在Windows机器上？ （在Windows Server 2008 R2，IIS 7）

How can I accomplish this on a Windows machine? (Windows Server 2008 R2, IIS 7)

简而言之，你需要安装 IIS URL重写添加 - 并创建一个规则，看起来是这样的：

In a nutshell, you need to install the IIS URL Rewrite add-on and create a rule that looks something like:

<rule name="Prevent image hotlinking">
  <match url=".*.(gif|jpg|png)$"/>
  <conditions>
    <add input="{HTTP_REFERER}" pattern="^$" negate="true" />
    <add input="{HTTP_REFERER}" pattern="^http://foo.com/.*$" negate="true" />
  </conditions>
  <action type="Rewrite" url="/images/say_no_to_hotlinking.jpg" />
</rule>

您的规则可能会略有不同，当然。通过URL重写，你也可以把你当前的.htaccess规则，并直接导入它作为一个新的规则。这将处理翻译，你虽然取决于你的目标，你可能需要进行一些小的改动，以生成所产生的规则。

Your rule may look slightly different of course. With URL Rewrite, you can also take your current .htaccess rule and import it directly as a new rule. It will handle the translation for you although depending on your objectives, you might need to make some minor changes to the resulting rules that are generated.

希望有所帮助。
