How do you get the PAGE.MAINDOMAIN.com instead of MAINDOMAIN.com/PAGE

Question

Instead of youtube.com/studio, it is studio.youtube.com

How does that work?
Is there a way to make it like that?

Or, maybe its not a page, but whatever it is how can you make it like that?

I don’t know what it is called, so that’s why I explained it like that.

youtube.com/studio/...

VS

studio.youtube.com/...

Answer 1

You need Apache or Nginx server to redirect the website.com and subdomain.website.com to different web folders.
