In Unix or Linux Apache with mod_rewrite this is easy.

Simply add the following to your .htaccess file in your public_html directory.

RewriteEngine on
RewriteBase  /
RewriteCond %{HTTP_HOST}   !^www.domain.com [NC]
RewriteCond %{HTTP_HOST}   !^$
RewriteRule ^(.*)         http://www.domain.com/$1 [L,R]

If you have subdomains, this will redirect all of them to http://www.domain.com/, to prevent this do the following:

RewriteEngine on
RewriteBase  /
RewriteCond %{HTTP_HOST}   !^www.domain.com [NC]
RewriteCond %{HTTP_HOST}   !^subdoamin1.domain.com [NC]
RewriteCond %{HTTP_HOST}   !^subdomain2.domain.com [NC]
RewriteRule ^(.*)         http://www.domain.com/$1 [L,R]
