htaccess redirect for subdomains

Question

Currently, I have a website (example.com). http to https redirect is working via my .htaccess file

RewriteEngine On
RewriteCond %{HTTP:X-Forwarded-SSL} !on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

This website also runs on subdomains.

If someone goes to www.subdomain.example.com of the website, I want them to be redirected to https://subdomain.example.com .

Is it possible to achieve this with the htaccess file without impacting the http to https redirect that I have working for example.com?

Thanks!

Answer 1

Yes, you can add multiple conditions.

RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} ^www\.subdomain\.example\.com$ [NC]
RewriteRule ^(.*)$ https://subdomain.example.com/$1 [R=301,L]

RewriteCond %{HTTP:X-Forwarded-SSL} !on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

1: If the HOST is www.subdomain.example.com , redirect to https://subdomain.example.com/

2: If its not https , redirect to https .
