We are porting an old project to umbraco 8. Umbraco 9 wasn't stable yet when we started so its too late now.

Anyway, one of the features is the urlrewriting.config

Syntax looked like this

<add name="productspecialrequest"
        virtualUrl="^~/product/category/(.*)"
        destinationUrl="~/product/category.aspx?pname=$1"
        ignoreCase="true" />

or

<add name="productspecialrequest2"
        virtualUrl="^~/product/category/(.*)/(.*)"
        destinationUrl="~/product/category.aspx?pname=$1&something=$2"
        ignoreCase="true" />

We liked this version because we just pass it in a query string then it catches anything after /category/ then use this to search for content from another non-umbraco database.

How do you do this now in umbraco 8?
