Ah sorry, this one was meant for you Denis, not sure how gmail handled it.

Thanks again. I understand the map solution. Here's another issue, you
see, the links below all map to the index page (there are other pages
too, that have those PageID, ParentPageID, etc.. parameters).

/index.cfm?PageID=1
/index.cfm?resetCache=yes
/index.cfm?PageID=1&ParentPageID=1&NavID=1
/index.cfm?PageID=22&ParentPageID=1&NavID=22
/index.cfm?PageID=14&ParentPageID=38&NavID=38&ReferringPage=1

all map to / (index)

/index.cfm?PageID=35&ParentPageID=26&NavID=26
/index.cfm?PageID=35&ParentPageID=26&NavID=35&ProductID=8&PageText=off
/index.cfm?PageID=35&ParentPageID=26&NavID=35&ProductID=9&PageText=off
/index.cfm?PageID=35&ParentPageID=26&NavID=35&ProductID=10&PageText=off
/index.cfm?PageID=35&ParentPageID=26&NavID=35&ProductID=15&PageText=off
/index.cfm?PageID=35&ParentPageID=26&NavID=35&ProductID=16&PageText=off
/index.cfm?PageID=35&ParentPageID=26&NavID=35&ProductID=11&PageText=off

and these for example would map to another unique page.

The parameters specify the actual page that must be mapped to. And
since I now know I can't use regex on query parameters, is there a way
to handle this situation?
