出站Web.Config URL重写

Question

通过这种方式，我可以重定向入站：

<rewriteMaps>
    <rewriteMap name="StaticRewrites">
      <add key="/documentation.html" value="/support" />

通过这种方式，我可以重定向出站：

<rules>
    <rule name="breaking changes 12 redirection" stopProcessing="false">
      <match url="support/breaking_changes_12" ignoreCase="true" />
      <action type="Redirect" url="https://company.zendesk.com/hc/en-us/articles/360015680XXX-Breaking-Changes-12" redirectType="Permanent" appendQueryString="true" logRewrittenUrl="true" />
    </rule>
    <rule name="breaking changes redirection" stopProcessing="false">
      <match url="support/breaking_changes" ignoreCase="true" />
      <action type="Redirect" url="https://company.zendesk.com/hc/en-us/sections/360002839XXX-Older-versions" redirectType="Permanent" appendQueryString="true" logRewrittenUrl="true" />
    </rule>

问题在于它总是在breaking_changes上赢得breaking_changes_12。如何避免这种情况？我在做什么错了？

谢谢。
