IIS 7.5使用IP地址将某些请求重定向到其他服务器

问题描述：

这是我苦苦挣扎了一段时间的问题.
我在服务器I 中托管了一个地址为 www.mywebsite.com 的网站，但该网站的图像来自服务器II (IP:1.2.3.4)，因此，如果有诸如 www.mywebsite.com/images/123.jpg 之类的请求，我想将它们重定向到图像服务器(服务器II ).

Here is a problem I have been struggling with for a while.
I host a website with the address www.mywebsite.com in server I but the images of the site come from server II (ip: 1.2.3.4) so if there are requests such as www.mywebsite.com/images/123.jpg I would like to redirect them to the image server(Server II).

我希望包含(.* jpg.*)正则表达式的请求将重定向到服务器II .

I would like that requests that contain (.*jpg.*) regex will redirect to Server II.

使用Url重写，我添加了一条规则:

Using Url rewrite I added a rule:

<rewrite>
        <rules>
            <rule name="Ignore images requests" enabled="true" stopProcessing="true">
                <match url="(.*jpg.*)" />
                <action type="Rewrite" url="https://www.petfinder.com/wp-content/uploads/2012/11/91615172-find-a-lump-on-cats-skin-632x475.jpg" />
            </rule>
        </rules>
    </rewrite>

如您所见，它将请求重写为静态图像，如何定义它以转到 1.2.3.4/images/imagename.jpg ?

It rewrites the request to a static image as you can see, how can I define it to go to 1.2.3.4/images/imagename.jpg?

最好的解决方案是，如果我只能通过宿主文件忽略包含 jpg 的请求，有办法吗?

The best solution would be if I could just ignore requests containing jpg via my host file, is there a way to that?

答

您重定向的规则应如下所示:

You redirect rule should be like that:

<rule name="image redirect" stopProcessing="true">
    <match url=".*" />
    <conditions logicalGrouping="MatchAll">
        <add input="{REQUEST_FILENAME}" pattern="(.*?)\.jpg$" />
        <add input="{REQUEST_FILENAME}" matchType="IsFile" />
    </conditions>
  <action type="Redirect" url="http://1.2.3.4/{R:1}" appendQueryString="false" />                           
</rule>

它将所有请求重定向到扩展名为 .jpg 的文件到1.2.3.4域例如:

It will redirect all requests to files with .jpg extension to 1.2.3.4 domain For example:

http://www.mywebsite.com/dog-1210559_960_720.jpg 到 http://1.2.3.4/dog-1210559_960_720.jpg

http://www.mywebsite.com/UserFiles/Entities/TopBanners/top50161616‌_586.jpg 至 http://1.2.3.4/UserFiles/Entities/TopBanners/top50161616‌_586.jpg
