.htaccess redirect url example

If I want to direct the non-www version of whhsupport.com to the www version I would place the following code into my .htaccess file:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^whhsupport.com
RewriteRule (.*) http://www.whhsupport.com/$1 [R=301,L]

Conversely, if I want to direct the www version of whhsupport.com to the non-www version, I would enter the following code into my .htaccess file:

RewriteEngine on
Options +FollowSymLinks
RewriteCond %{HTTP_HOST} ^www\.whhsupport\.com$ [NC]
RewriteRule ^(.*)$ http://whhsupport.com/$1 [R=301,L]
