nodejs uppercase headers hack

gistfile1.js

var http = require('http');

var automaticHeaders = {
  connection: true,
  'content-length': true,
  'transfer-encoding': true,
  date: true
};

http.OutgoingMessage.prototype.setHeader = function(name, value) {
  if (arguments.length < 2) {
    throw new Error('`name` and `value` are required for setHeader().');
  }

  if (this._header) {
    throw new Error('Can\'t set headers after they are sent.');
  }

  // NO LOWER CASE
  var key = name//.toLowerCase();
  this._headers = this._headers || {};
  this._headerNames = this._headerNames || {};
  this._headers[key] = value;
  this._headerNames[key] = name;

  if (automaticHeaders[key]) {
    this._removedHeader[key] = false;
  }
};

oh yea.. i suppose automaticHeaders is defined in express somewhere and I didn't transfer that over in my implementation.. whoops!
