How to implement a redirect to https on internal pages?

Question

htaccess

There is a rule:

RewriteCond %{SERVER_PORT} 80
RewriteCond %{HTTP_HOST} ^site\.ru
RewriteRule ^(.*)$ https://www.site.ru/$1 [R=301,L]

If I type http://site.ru in the address bar of the browser, then the redirect to https works.
But if I specify an internal page in the address bar, for example site.ru/files/file-manager.html, then, alas, I don’t see a redirect.
Important clarification: the www prefix is ​​required.
