Multiple domains on one hosting account

If your hosting plan allows for multiple domains on one hosting account, you can request the add-on domains to be added using the trouble ticket section inside the members area.
Once the support department has added the domain(s) to your account, you will need to create a .htaccess file in the directory /var/www/html

Obviously change abc.com to your real domain name:

RewriteEngine On
Options +FollowSymLinks
RewriteCond %{HTTP_HOST} abc.com$ [NC]
RewriteCond %{REQUEST_URI} !^/www.abc.com/.*$
RewriteRule ^(.*)$ /www.abc.com/$1
