How to redirect to another web with same domain

Hi!

It's possible to have a domain and when a user for a specific country connect to that web, nginx redirect to another web but without change the domain.

for example:

i have tha domain www.example.com and if an users open that web in America they see a youtube.com but the domain still be www.example.com and if users connect from Europa the see the real web.

Regards.
