How to correctly redirect domains to specific folders using .htaccess?

Question

Apache HTTP Server

Hello!
Please tell me how to set up .htaccess correctly
. There are 3 domains:
site1.ru,
site2.ru,
site3.ru
site files are in the same root directory public_html, for each domain there is a folder public_html/site1,
public_html/site2,
public_html/site3,
how to configure .htaccess so that each domain is redirected to the appropriate folder?

Answer 1

You need to create virtual hosts with document roots pointing to these folders.
This is not done through .htaccess.
