var request = request.defaults({
  jar: jar,
  followAllRedirects: true

var jar = request.jar();

request.post({
    url: 'http://www.tremorgames.com/index.php',
    headers: {

    'Connection':'keep-alive', 
    'Cache-Control':'max-age=0',

i have made some console.logs() to try to find out what is going on, and the only cookie the request are saving are some PHPSESSID, i have already asked google but i dont find anything relevant or anything i can get it :/
