I've literally just been working on the same thing today and here's what I came up with.

Stick this in your .htaccess file in the root of your site. This obviously relies on Apache and Mod_rewrite.

RewriteEngine on
RewriteBase /

# Redirect content to the CDN

RewriteCond %{HTTP_HOST} !^cdn\.server\.com$    [NC]
RewriteRule .*\.(jpg|gif|png|flv|css|js|swf)$   http://cdn.server.com/$0    [R=301,L]

This will send requests for the file types in the brackets to your cdn and keep requests for other types on your primary server.
