Question about "GenericUrl" route

I have this URL: http://localhost:2619/test-product-1

The route debugger says the matched route is the "generic_se_name", which is connected to the "GenericUrl" action on the "Common" controller.  Inside that action is simply a redirect to the home page.

My question is, how exactly then is it correctly displaying the product?  I'm confused as to how its getting to the product correctly when the mapped action is simply a redirect to the home page.

I feel like I'm missing something simple here.  Thanks in advance.

Please Look what MapGenericPathRoute does? I think your answer is here.
It will redirect the url by getting the exact slug and entity from database and redirect them entity-wise.
For that see class GenericPathRoute.cs in Nop.Web.Framework.Seo

Exactly what I was missing.  Thanks!
