server-side browser detection? node.js

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.
