Iis URL重写-如果匹配特定字符串，则删除URL结尾

使用URL重写，我们有很多旧的URL

/something/else/index.cfm
/this/that/index.cfm

我想做的是从这些示例中删除

/index.cfm

有什么想法吗

谢谢

<rule name="Remove Trailing Index.cfm" enabled="true">
    <match url="^(.*)/index.cfm" />
    <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
        <add input="{R:1}" pattern="category" negate="true" />
        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
    </conditions>
    <action type="Redirect" url="/{R:1}" />
</rule>
