How to make a 301 redirect from one domain to another and not to do a redirect for each page, but to register once and the pages will also be redirected?

Answer 1

Add the following lines to the .htaccess file located in the folder of the site you want to redirect from:
RewriteEngine On
RewriteCond %{HTTP_HOST} old-site.ru
RewriteRule (.*) new-site.ru/$1 [R=301, L]
Where:
old-site.ru is the domain from which the redirect occurs;
new-site.ru is the domain to which the redirect occurs.
