Is it possible to have a different domain for a subfolder?

After delivering a one-page website for a client, they’ve requested the addition of a subfolder or another page with a new domain name. Specifically, they want to transition from our main site, www.abc.com/subfolder, to a new domain, www.xyz.com, while ensuring both domains function simultaneously. So the main domain (www.abc.com) will still take people to the real home page while second domain (www.xyz.com) will bring people to the subfolder. Is this possible?

In native Webflow, that’s just two separate sites.

In advanced situations, such as for clients who build a lot of lead funnels, I’ll use a reverse proxy to break down a single Webflow-hosted site into multiple lead-funnel pages with discrete domains, sitemaps, etc.
