Thanks for your reply. Actually there is a great universal script, updated almost daily with new browser / client information and a built in PHP function that can be used to get client side information asp or php. I like this better because it works directly with server side scripting and reduces client side scripting (load time). If you need to have it setup on a per site basis use this code.
$browser = get_browser(null, true); //If available, use PHP native function
