当然，我发布后很快就想通了.这样做了，但不确定为什么精确匹配不起作用.

Of course I figured it out soon after I posted. This does it, not really sure why the exactmatch wasn't working though.

<rule name="Node17" stopProcessing="true">
    <match url=".*" />
<conditions>
    <add input="{QUERY_STRING}" pattern="q=node/17" />
</conditions>
<action type="Redirect" url="http://www.site.com" appendQueryString="False" />
</rule>
