Most implementations i've seen are for browser detection on the client side. I was just wondering if it was possible to do browser detection before sending any resources to the client.
Thanks.
var ua = request.headers['user-agent'],
$ = {};
if (/mobile/i.test(ua))
$.Mobile = true;
if (/like Mac OS X/.test(ua)) {
$.iOS = /CPU( iPhone)? OS ([0-9\._]+) like Mac OS X/.exec(ua)[2].replace(/_/g, '.');
$.iPhone = /iPhone/.test(ua);
$.iPad = /iPad/.test(ua);
}
if (/Android/.test(ua))
$.Android = /Android ([0-9\.]+)[\);]/.exec(ua)[1];
if (/webOS\//.test(ua))
$.webOS = /webOS\/([0-9\.]+)[\);]/.exec(ua)[1];
if (/(Intel|PPC) Mac OS X/.test(ua))
$.Mac = /(Intel|PPC) Mac OS X ?([0-9\._]*)[\)\;]/.exec(ua)[2].replace(/_/g, '.') || true;
if (/Windows NT/.test(ua))
$.Windows = /Windows NT ([0-9\._]+)[\);]/.exec(ua)[1];
That should work for you. Just put it in your response handler.
