Im going over a design from 4.1 to 5.1. We are rebuilding from scratch and looking at what has been done on the 4.1 server over the years. How valid are Route Filters and in what situations are they used best in? Seems to me that Route Patterns can take over most the work that needs to be routed. But Im trying to figure out if it is a requirement to use Route Filters or to just skip over them.
