Add connect-favicons to your middleware stack before everything else. The whole point here is to serve favicon.ico and apple-touch-icon.png (et al.) quickly, without involving any routing.

In this case, you may have all your site icons, including favicon.ico in /public/img/icons:

app.use(favicons(__dirname + '/public/img/icons'));

Now any request to the example.com/favicon.ico or example.com/apple-touch-icon.png will be served by Connect Favicons, reading from the folder you specified.

var http     = require('http');
var path     = require('path');
var express  = require('express');
var favicons = require('connect-favicons');

var app = express();

// Middleware stack
app.use(favicons(__dirname + '/public/img/icons'));
app.use(express.static(path.join(__dirname, '/public')));

http.createServer(app).listen(3000, function(){
    console.log("Express server listening on port " + 3000);
});
