Is it possible to redirect only from the main page without affecting child pages?

Question

PHP

Tell me if it is possible to redirect only from the main page of the site (for example, from www.test.ru to another site www.toster.ru), but from its child pages (for example, from www.test.ru/news/ or www.test. ru/news.php?id=32) so that there is no redirect. Thank you.

Answer 1

Normal 301 redirect

Answer 2

RewriteRule ^/$ http://example.org/ [L,R=301]

Answer 3

no, it doesn't work now, I'll look into it in detail, maybe I'm doing something wrong,
RewriteEngine On
RewriteRule ^/$ example.org [L,R=301]

Answer 4

RewriteEngine On
RewriteCond %{REQUEST_URI} ^/$
RewriteRule ^(.*)$ example.org [L,R=301]
