Question

How to fix rewrite rule, so that it works also trough domain.com/path/.htaccess?

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

If rule used in domain.com/.htaccess, redirecting works fine:

www.domain.com/path/url -> domain.com/path/url

If rule used in domain.com/path/.htaccess, redirected incorrect:

www.domain.com/path/url -> domain.com/url // Why not domain.com/path/url ?

%{REQUEST_URI} provides you the full path:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule .* http://%1%{REQUEST_URI} [R=301,L]
