var http = require('http');

var server = http.createServer();

server.listen(8000);

server.on('request', function(req, res) {
  http.get("http://google.com/index.html", function(response) {
    req.on("end", function() {
      console.log("ENDED");
    });
  });
});

console.log is never called

The end listener is attached too late. The event has already fired.

This ensures that the handler is attached.

var http = require('http');

var server = http.createServer();

server.listen(8000);

server.on('request', function(req, res) {

  req.on("end", function () {
    console.log("ENDED");
  })

  http.get("http://google.com/index.html", function(response) {
    console.log(response.statusCode);
  });
});

In v0.10, this is quite different!

// works on v0.10, not on v0.8
var http = require('http');

var server = http.createServer();

server.listen(8000);

server.on('request', function(req, res) {
  http.get("http://google.com/index.html", function(response) {
    req.resume()
    response.pipe(res)
    req.on("end", function() {
      console.log("ENDED");
    });
  });
});

Because stream 'end' doesn't happen until you consume the request, it actually hasn't happened yet.

So, instead of missing the 'end' like you would on v0.8, it's hanging waiting for you to consume the stream, because it starts out paused until you consume it.

Nice to know Isaacs. Thanks for the tip
