How do I force canonical URL in Grav?

Good evening my friends,

I’m happy to use Grav for my personal blog and site. I’ve always been an anti-mainstream guy.

Anyway, I found out my site is both accessible at and I wish the latter to remain, and whenever it’s accessed without the “www.” redirect permanently to the “www.” version.

How’d I achieve this? I tried modifying it with custom_base_url, but I think I’m doing it wrong.

Thanks in advance,

Solved it myself with .htaccess wizardry.

I added the following:
RewriteCond %{HTTP_HOST} ^mydomain\.com$ [NC]
RewriteRule ^(.*)$ "https\:\/\/www\.mydomain\.com\/$1" [R=301,L]

Before the rules of:
RewriteCond %{REQUEST_URI} !^/index\.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php [L]
