node.js - nodejs - http.createServer seems to call twice

Question

If I write the following program in node:

  http.createServer(function (req, res) {

    if( req.method == 'GET' ) {
      var body = ''; req.on('data', function(data) { body += data });
      req.on('end',  function() {
        console.log('request ended')
      });
    }

    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('142
');
  }).listen(3500);

And then hit the server with http://xxx.xx.xxx.xx:35010 I see a request ended twice on my console -- I'm not sure why a single HTTP request is causing this to execute twice.

Answer 1

That is normal - your browser makes more than one call.

Most browsers make a call to grab /favicon.ico for example.

Try to log the url:

console.log(req.url);

and you'll see what's being called.
