Example script of how `request` (and node) drops any `query` param passed to http.request()

request-query.js

var http = require('http')
  , assert = require('assert')
  , request = require('./')
  , url = require('url')
  , path = 'http://localhost/test'

http.createServer(function (req, res) {
  assert.equal('/test?foo=bar', req.url)
  res.end()
}).listen(0, function () {
  var port = this.address().port
    , parsed = url.parse(path, true)
  // Overriding the requested port works fine:
  parsed.port = port
  // But any 'query' value will be completely ignored
  parsed.query.foo = 'bar'

  request({
      method: 'GET'
    , uri: parsed
  }, this.close.bind(this))
})
