.htaccess - htaccess redirect domain to https, subdomain to http and www to non-www

Question

I’m trying to do that:

Force the https for my main domain.

http or https://www.domain.com  -> https://domain.com
http or https://domain.com  -> https://domain.com

But not for subdomains

http or https://www.subdomain.domain.com -> http://subdomain.domain.com
http or https://subdomain.domain.com -> http://subdomain.domain.com

And always removing the www.

Now i have that:

RewriteCond %{HTTP_HOST} ^www.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

This redirects www to non-www and http to https but not for subdomains. The subdomain remains with www and the https.

Thanks

You can use these 2 rules:

# for main domain
RewriteCond %{HTTP_HOST} ^(www.)?domain.com$ [NC]
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^www. [NC]
RewriteRule ^ https://domain.com%{REQUEST_URI} [R=301,L,NE]

# for sub domain
RewriteCond %{HTTP_HOST} ^(www.)?subdomain.domain.com$ [NC]
RewriteCond %{HTTPS} on [OR]
RewriteCond %{HTTP_HOST} ^www. [NC]
RewriteRule ^ http://subdomain.domain.com%{REQUEST_URI} [R=301,L,NE]
