.htaccess redirects from https to http and back, what to do?

Question

htaccess

There is a store on opencart 3.0 with a customized cnc (Seo pro). Redirect to https is connected through the hosting.
To save links from the old site, a list of "hard" 301 redirects of the form was created: (xxx old link with opencart prefix, yyy - new link)

RewriteCond %{QUERY_STRING} ^_route_=xxx$
RewriteRule ^(.*)$ /yyy? [R=301,L]

The redirect works, but there was a problem, an intermediate redirect to http appeared.
It turns out such a chain: link to the old-> link to the new c http-> https-> link with a slash


Please help me, how to get rid of this intermediate http-> https redirect?

Answer 1

Add full address with https and domain.

RewriteCond %{QUERY_STRING} ^_route_=xxx$
RewriteRule ^(.*)$ https://site.ru/yyy? [R=301,L]
