Trying to auto-resume a paused stream by piping (not working)

index.js

var http = require('http');

http.createServer(function (req, res) {
  console.log('Got request');
  req.pause();

  var size = 0;
  req.on('data', function (chunk) {
    console.log('Counting...');
    size += chunk.length;
  });
  req.on('end', function () {
    console.log('Size of request:', size);
  });

  console.log('Piping...');
  req.pipe(res);
}).listen(3000);
