// early experiments with node had mysterious double requests
// turned out these were for the stoopid favicon
// here's how to short-circuit those requests
// and stop seeing 404 errors in your client console
 
var http = require('http');
 
http.createServer(function (q, r) { 
 
  // control for favicon
 
  if (q.url === '/favicon.ico') {
    r.writeHead(200, {'Content-Type': 'image/x-icon'} );
    r.end();
    console.log('favicon requested');
    return;
  }
 
  // not the favicon? say hai
  console.log('hello');
  r.writeHead(200, {'Content-Type': 'text/plain'} );
  r.write('Hello, world!');
  r.end();
  
}).listen(8000);
 
console.log('Server running at http://127.0.0.1:8000/');

In case someone stumbles upon this in the future.. If you are running nginx in front of node.js you can also block favicon requests by adding this line:

location = /favicon.ico { access_log off; log_not_found off; }

If you are using express you can do it like this

app.use(express.favicon(__dirname + '/public/favicon.ico'));
