Thanks for replying. But I don’t quite get it yet.
Let’s take Webflow as an example…
This is the main site created by Webflow and is hosting on Webflow.
https://webflow.com
( A ) A separated Webflow site, but putting it under the another Webflow site.
No idea how to do this as well. ( I created another post for this. )
https://webflow.com/blog
( B ) A Webflow site hosted under a subdomain, easy and straight-forward.
https://university.webflow.com
( C ) A custom site or application under a Webflow site.
On a sub-directory; no redirect, not using a subdomain.

The way ( C ) configured is about what I would like to archive. I would like to build a web-based application as if part of the main website (www.domain.com, a Webflow site) and but it is actually hosting on AWS, and the URL would be www.domain.com/app.
Thanks.
