How to organize a 301 redirect from http://www to https://?

Question

htaccess

Hello, we have moved to the https protocol.
Used by ISPManager 5
In the domain settings in isp, the item "Redirect HTTP requests to HTTPS" is checked.
http is redirected to https without problems.
But here's how to set up a redirect from http: //www directly to https:// without www?
The fact is that if you specify in .htaccess

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

then when accessing www.site.ru, the following chain is obtained:
www.site.ru -> [301] https://www.site.ru -> [301] https://site.ru
Tell me how to exclude from the chain https://www.site.ru, so that when accessing www.site.ru, a redirect is carried out immediately to https://site.ru?

Answer 1

Make a separate virtual host config in Apache for www and immediately redirect from it to without www with https. So it will be easier and clearer than fencing rules in htaccess.
In Spanish, this can be done in the config tab in www-domains.
