I'm trying to rewrite certain CSS files with some rules, so it replaces every single instance of links in the CSS (as in background: url("/myuri.jpg")) with a prefix (as in background: url("/zeus/myuri.jpg"))

These are the rules.

<rule name="ReverseProxyOutboundRule2" preCondition="IsCSS" enabled="true" stopProcessing="false">
    <match filterByTags="None" pattern="url\(&quot;(.*)&quot;\)" />
    <action type="Rewrite" value="url(&quot;/zeus{R:1}&quot;)" />
    <conditions>
        <add input="{URL}" pattern="/zeus" />
    </conditions>
</rule>

<preCondition name="IsCSS">
    <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/css" />
</preCondition>

However, only one url is being replaced this way and somehow the rest is being ignored.

Thank you beforehand.
