mod rewrite is not affected for domain without www?

i have this setting for apache :
<VirtualHost mysite.co.id:80>
ServerAdmin admin@mysite.co.id
DocumentRoot /var/www/html/main
ServerName mysite.co.id
ErrorLog logs/mysite.co.id.error
CustomLog logs/mysite.co.id.access common
<Directory "/var/www/html/main/">
Options +Indexes MultiViews FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</Directory>
RewriteEngine On
RewriteRule ^/sub1(.*) http://sub1.mysite.co.id$1 [NC,R,L]
</VirtualHost>
<VirtualHost beta.mysite.co.id:80>
ServerAdmin admin@beta.mysite.co.id
DocumentRoot /var/www/html/beta
ServerName beta.mysite.co.id
ErrorLog logs/beta.mysite.co.id.error
CustomLog logs/beta.mysite.co.id.access common
<Directory "/var/www/html/beta/">
Options +Indexes MultiViews FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</Directory>
RewriteEngine On
RewriteRule ^/sub1(.*) http://sub1.beta.mysite.co.id$1 [NC,R,L]
</VirtualHost>
<VirtualHost www.mysite.co.id:80>
ServerAdmin admin@www.mysite.co.id
DocumentRoot /var/www/html/main
ServerName www.mysite.co.id
ErrorLog logs/www.mysite.co.id.error
CustomLog logs/www.mysite.co.id.access common
<Directory "/var/www/html/main/">
Options +Indexes MultiViews FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</Directory>
RewriteEngine On
RewriteRule ^/sub1(.*) http://sub1.www.mysite.co.id$1 [NC,R,L]
</VirtualHost>
this condition will redirect for all sub1 folder accessed will be redirect
to our new subdomain sub1.
