This is an important script most webmasters should use on their pages. It redirects users and bots from domain.com to www.domain.com. This is ultra-important for search engine optimization. Many search engines penalize for duplicate content (by accident, bots can index domain.com seperatly from www.domain.com causing duplicate content! Anyways, create a new document named '.htaccess', add the below code, and put it in your root directory!

Code:
Options +FollowSymLinks
RewriteEngine On

RewriteCond %{HTTP_HOST} ^domain\.com
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=permanent,L]
