Redirects in .htaccess file for non-www domains except subdomains and dev domains

Question

I will redirect all non-www domains in my Laravel .htaccess to a www-domain , except subdomains and development domains (*.app).

I have an application with multiple domainnames, now I use a long list in my htaccess, but that's a bad way...

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

RewriteCond %{HTTP_HOST} ^example1.com [NC]
        RewriteRule (.*) https://www.example1.com/$1 [R=301,L]

# etc... a very long list...

How can i redirect all non-www-domains to a www-version:

• except normal subdomains (like http://sub.example.com )
• except my development domains (like example.app)

You can use a single rule like this:

RewriteEngine On

RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} !\.app$ [NC]
RewriteCond %{HTTP_HOST} !^[\w-]+\.[\w-]+\.(com|be|de|co\.uk)$ [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI{ [R=301,NE,L]
