Cannot use Composite.Core.Routing.Pages.C1PageRoute.RegisterPathInfoUsage() on secondary hostnames' home page

[NimeCloud]

Hi!

I've got a main domain and a few secondary domains.

Main: izsmmmo.org.tr
Secondary : izsm.link
I also get the secondary site using page link on main domain: izsmmmo.org.tr/link

I need to intercept the first query string. On the main domain it works: https://izsmmmo.org.tr/link/random3732
I get "random3732" as expected.

However; at the secondary domain I got 404 error: https://izsm.link/random3732

If I left the query empty; the page appears with no error: https://izsm.link/

It seems like Composite.Core.Routing.Pages.C1PageRoute.RegisterPathInfoUsage(); won't work on secondary domains' root page.

Is it bug or feature and how can I fix it? I don't want to use another page https://izsm.link/go/random3732 if possible...

Secondary site is ok without any query:

Secondary site doesn't love queries; the expected responses are 200 or 400. I got 404 here:

Primary site is ok. It gives a 400 error if query not found on database:
