URL redirect issue ASP.NET

[quypro]

I'm having a problem where the redirects are all redirecting to the same page, I need them to redirect to an exact matched page not just a partial match.Ex: product.asp?dtlid=2 should go to page A product.asp?dtlid=212 should go to page BSeems like both both pages go to product A because the 1st number is a 2 in both instances, my code is below. thanks in advance.\[code\]<rule name="RedirectP251" stopProcessing="true"> <match url="catalog/details.asp$" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="true"> <add input="{QUERY_STRING}" pattern="dtlid=2" /> </conditions> <action type="Redirect" url="http://www.sitename.com/producta.mvc" appendQueryString="false" redirectType="Permanent" /> </rule><rule name="RedirectP671" stopProcessing="true"> <match url="catalog/details.asp$" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="true"> <add input="{QUERY_STRING}" pattern="dtlid=211" /> </conditions> <action type="Redirect" url="http://www.sitename.com/productb.mvc" appendQueryString="false" redirectType="Permanent" /> </rule> \[/code\]
