I forgot to mention, in PHP the user agent string is in
$_SERVER['HTTP_USER_AGENT'], and in javascript you can find it in
navigator.userAgent.
Where you want to redirect, it's up to you. If you want it to do on first
attempt, better go with PHP so you can use Header("Location: ...") to
redirect the user immediately so the user won't notice he is being
redirected.
