.htaccess redirect folder to subdomain

Question

I've tried applying a few of the answers found on stackoverflow, but either I'm missing something or I'm plain dumb.

Basically I got a main domain name. This domain already has a non-www redirect. So http://domain.com becomes http://www.domain.com. This domain also has a mobile version found inside the the 'm' folder. So accessing the domain name like http://www.domain.com/m/ works and so does http://m.domain.com. What I'm trying to achieve is simple: anyone whom goes to the site via http://www.domain.com/m/, or http://www.domain.com/m/about should be redirected to the subdomain version so to http://m.domain.com or http://m.domain.com/about in the second case listed above.

Whatever I tried implementing ended up with errors, either I managed to disable direct access to m.domain.com, but it worked via domain.com/m/, or redirect loops.

Thanks!

You can use this code in your DOCUMENT_ROOT/.htaccess file of domain.com main .htaccess:

RewriteEngine On

RewriteCond %{HTTP_HOST} ^(?:www\.)?(domain\.com)$ [NC]
RewriteRule ^m/(.*)$ http://m.%1/$1 [L,NC,R=302]

# non-www to www
RewriteCond %{HTTP_HOST} !^(m|www)\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [L,NC,R=302]
