Browser Detection and Redirection

[j00sh]

I am wondering, how I would detect all browsers (other than http_user) so I can detect all versions of netscape, IE, opera, etc. and then redirect them to the appropriate page. If they have firefox, I want to get them to go on the page with out being redirected.

Any ideas? I searched for tutorials but couldnt find exactly what I need.

How about: www.php.net/get_browser

Alternatively, you could search for the string 'firefox' in $_SERVER['HTTP_USER_AGENT']
