Apache: how to make subdomains like folders?

Question

Apache HTTP Server

There is a site.com domain. How can I make all *.site.com requests work as site.com/* (where "*" is any subdomain. for example: blog, about, account ...) ?
Tried like this:

<VirtualHost *:80>
    ServerAlias *.site.com
    RewriteEngine On
    RewriteCond %{HTTP_HOST} ^((.*)\.)site.com$
    RewriteRule ^/(.*) /%2/$1
    DocumentRoot /home/site.com/www
    <Directory /home/site.com/www>
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

but it didn't work out

Answer 1

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.site.com$
RewriteCond %{HTTP_HOST} ^((.*)\.)site.com$
RewriteRule ^/(.*) /%2/$1
