If you activate CloudFlare through HostArmor, CloudFlare can only accelerate and protect CNAMEs, not A records, which often includes the root domain. If you have traffic that goes to your root domain and you want to accelerate and protect the traffic using CloudFlare, you can add a redirect to ‘www’ in your .htaccess file. You should work with HostArmor, but as a general outline, a redirect looks as follow:
RewriteEngine On
# Rewrite added for CloudflareInstall - mysite.com
# Wednesday 25th of August 2010 04:59:42 AM
RewriteCond %{HTTP_HOST} ^mysite.com$ [NC]
RewriteCond %{SERVER_PORT} ^80$
RewriteRule ^(.*)$ http://www.mysite.com/$1 [R=301,L]
