Here is a clean failure trace.  In it you can see the original url is ...

report/create/area/820/

 

this is rewritten to...

 

components/report/create.aspx?areaID=820

 

The trace shows this match on line 116.

 

The final url is...

 

http://localhost:80/components/report/create.aspx?areaID=820&UseUploadModule=Dynamic&_Namespace=CuteWebUI&_UploadID=ctl00_ctl00_ContentPlaceHolderContent_ContentPlaceHolderContentTrip_ReportEditControl_TabContainer_TabPanelMedia_MediasUploadControl_UploadAttachmentsImage_1231324875429_1&_UploadControlID=ctl00$ctl00$ContentPlaceHolderContent$ContentPlaceHolderContentTrip$ReportEditControl$TabContainer$TabPanelMedia$MediasUploadControl$UploadAttachments&ContextValue=!3wEWAWQ5poyVsnBArG6lJ6b7R2A4cKwMqA!2!2&_Addon=upload&_AddonGuid=7d30d6df-3548-4280-9ecf-32276f3ce99b

 

 

It then goes on to make a request to that url.

 

So it looks to me the the url rewriting is working fine to this point.
