Hello Rich, to do this you don't need any special library.. you can just check one HTTP header which is named "User-Agent" Sergio Freire at 6:46 AM on Sunday June 18th, 2006
in Ruby this is as easy as looking at the request and accessing that "User-Agent" header by doing a @request.env['HTTP_USER_AGENT'] Sergio Freire at 6:53 AM on Sunday June 18th, 2006
a simple place explaining this is available at http://rails.techno-weenie.net/tip/2006/4/9/server_side_browser_detection Sergio Freire at 6:54 AM on Sunday June 18th, 2006
