Where in the source code is the URL Rewriting Logic?

I've looked everywhere and can't seem to figure out where this is being done. There's a class called "./web/App_Code/RewriteUrlLookupEngine.cs", but from what I can tell -- this class doesn't seem to be used anymore. I'm guessing it's the old way this was done.

It is happening in backend code in CommerceBuilder.Services.UrlRewriter
