My current URL is like this

http://mydomain.com/product-list?Type=AllProducts&ListCategory=Category&ListCriteria=All&KeyWord=109&CategoryName=mycategory

I want to hide the querry string values from user, so that a common user will see my site Url like this

http://mydomain.com/product-list/mycategory

I have tried to configure this in Urlrewriting.config like this

    <add name="produktidrewrite"
 virtualUrl="^~/product-list/(.*)"
 rewriteUrlParameter="ExcludeFromClientQueryString"
 destinationUrl="~/product-list?CategoryName=$1"
 ignoreCase="true" />

but it doesn't works. Can any one point out what I am doing wrong here?
