node.js and http CONNECT method

gistfile1.js

var http = require('http');

var server = http.createServer(function(req, res) {
  res.writeHead(200, {
    'Content-type': 'application/json'
  });
  res.end(JSON.stringify(http.STATUS_CODES));
}).listen(4000);

server.on('connect', function(req, socket, head) {
  // This doesn't fire when doing e.g. curl -X CONNECT localhost:4000
  console.log('CONNECT');
});

Doesn't have anything to do with node. Apparently -x should be used.
