Recommended way to support www and naked domain with Cookieplone

Working with Cookieplone what's the right way to support www and the naked domain?
This is a continuation from this conversation:

Traefik and Docker Swarm - Is traefik misconfigured?

you've both example.org and www.example.org. Volto sees a return_url that point to a different domain (example.org vs www.example.org) and maybe something goes wrong, I don't think Volto supports multiple web address. Better to redirect from www.example.org to example.org and manage just example.org.
