Routing diferent services for domain root and folders


Let's say we have a domain (ie: where a drupal will response, and then we have some folders redirecting to other webapps. Graphically it would be something like this:

The "drupal-root" has the following labels:

      - "traefik.enable=true"
      - ""
      - ""
      - "``)"

While sites are like follow:

      - "traefik.enable=true"
      - "traefik.http.routers.service1-app.entrypoints=websecure"
      - "traefik.http.routers.service1-app.tls=true"
      - "traefik.http.routers.service1-app.rule=Host(``) && PathPrefix(`/webapp1`)"

Are those settings fine to make all work as expected or will drupal-root get all the traffic?
In other words, how traefik define the priorities?

I'm asking because I made some tests and I get wired results (some services work and others where redirected to drupal-root)... and I like to confirm settings are fine before keep digging.

Thanks in advance for your help,
