Rule worked in IIS7.5 but not IIS8

Hi guys,

Just looking for a bit of help with this rule which worked perfectly in IIS7.5 but just has no effect in IIS8. Maybe something has changed that I don't know about causing it to fail.

<rule name="Insert index.cfm" stopProcessing="true"><match url="^(.*)$" ignoreCase="false" /><conditions logicalGrouping="MatchAll"><add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" /><add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" /></conditions><action type="Rewrite" url="index.cfm/{PATH_INFO}" appendQueryString="true" /></rule>

Thanks,

Richard
