What to use instead of a domain for a redirect?

Question

Apache HTTP Server

There is a code

RewriteRule ^catalog/(.+)$ http://site.ru/$1 [R=301,L]

removes the catalog from the url

, how can I change it so that it works like that?

Answer 1

try leaving only the slashRewriteRule ^catalog/(.+)$ /$1 [R=301,L]
