I have multiple questions regarding multi websites in Odoo V15 :

- How can I host 2 websites on the same domain name and display the website I want depending on the country my visitors come from?

- How can I host my odoo websites on a specific domain name?

- Is it possible to display specific content on the website depending on the country of my visitor? For instance, I want only Belgian visitors to see a banner with a promo code for the e-commerce

- Is is possible to share pages and products across websites?
