Browser Sniffer Script (version 1.1). How to redirect users?

[tp4fp]

1) Script Title: Browser Sniffer Script (version 1.1)

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...sersniffer.htm

3) Describe problem: How can I get it so that if the user is using any of those browsers, it redirects to index_1.htm but if they are using a different browser than the ones in the script, it redirects to index_2.htm ?

if (!exclude)
window.location.href='index_1.htm';
else
window.location.href='index_2.htm';
