node.js - Browser not sending back cookies, but curl does -

i developing nodejs application scratch. beginning play node. building login system, found issue:

when login correct name , password, cookie set 'remember_token' value. supposed store user session. cookies in google chrome browser

the cookie set correctly, when browser makes new request, cookie value not set in server:

when make request trhoug curl, cookies recieved server:

curl -i 'http://localhost' -b "remember_token=znvuy3rpb24gbm93kckgeybbbmf0axzlignvzgvdih0wlja1ntg2mzu1mtu2mjy1mtk5" 

aditional info

i added lines app.js before middleware called:

app.use(function(req, res, next){   console.log('\nrequest: ' + json.stringify(req.headers));   next(); }); 

and output when make request browser:

request: {"host":"node","connection":"close","cache-control":"max-age=0","accept":"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8","user-agent":"mozilla/5.0 (x11; linux x86_64) applewebkit/537.36 (khtml, gecko) chrome/28.0.1500.95 safari/537.36","referer":"http://localhost/","accept-encoding":"gzip,deflate,sdch","accept-language":"es-419,es;q=0.8,en;q=0.6,en-au;q=0.4,en-ca;q=0.2,en-us;q=0.2,en-nz;q=0.2,en-gb;q=0.2,en-za;q=0.2","cookie":"connect.sid=s%3ab8g0vgivuiuot4a9dkl3wmfu.625hfc6w4timujyk4x9clfena0fi8pd%2fdmg0sspaw5e","if-none-match":"\"-651269513\""} 

no remember token cookie on header. tested in: google chrome, chromium , mozilla firefox. why this?

update

this how create cookies:

exports.identificar = function (req, res, success, fail) {     var remember_token = null;     var u;      usuarios.findbyemail(req.body.sesion.email,function(usuario){         if (usuario) {             crypt.comparepassword(req.body.sesion.password, usuario.password_digest, function(err, resp) {                 if (err) {                     fail('hubo un error de encripción');                 } else if (resp) {                     remember_token = usuario.remember_token;                      u = usuario.tojson();                          delete u['password_digest'];                         delete u['remember_token'];                         delete u['fecha_token'];                         delete u['token'];                      if (typeof req.body.sesion.recordar !== "undefined"){                         res.cookie('remember_token', remember_token, {expires: new date(date.now() + 900000), secure: true});                        } else {                         res.cookie('remember_token', remember_token, {secure: true});                     }                     req.session.usuario = u;                     success(u);                 } else {                     fail('contraseña incorrecta');                 }             });         } else {             fail('usuario no encontrado');         }     }); }; 

solved

i solved removing "secure:true" option in server when set cookie, but. why did happen?

the secure option secure connections, had remove "secure:true" flag on server when set cookie.
