Why does it close the connection after 1 minute?

event-stream.js

var sys = require('sys'), 
   http = require('http');

http.createServer(function (req, res) {

  res.sendHeader(200, {
    "Content-Type": "text/event-stream",
    "Cache-Control": "no-cache"
  });

  setInterval(function () {
    res.sendBody("data: " + (new Date()) + "\n");
    res.flush();
  }, 1000);

}).listen(8000);

sys.puts('Event stream running at http://127.0.0.1:8000/');
