This is my Angular js piece code:

$http({

                method:'POST',

                withCredential:true,

                url:$scope.config.app_ws+'auth/signup',

                data:{user:$scope.auth}

            }).success(function(status, response){



                console.log(response);

            }).error(function(status, response){

                alert(response+'Bummer :( , an error occured plese retry later. ');

            });

This is my Node.js piece backend:

 var allow_cross_domain= function(req, res, next) {

      res.header('X-Powered-By', 'hey.heyssssssss.org');



      var oneof = false;

      if(req.headers.origin) {

        res.header('Access-Control-Allow-Origin', req.headers.origin);

        oneof = true;

      }

      if(req.headers['access-control-request-method']) {

        res.header('Access-Control-Allow-Methods', req.headers['access-control-request-method']);

        oneof = true;

      }

      if(req.headers['access-control-request-headers']) {

        res.header('Access-Control-Allow-Headers', req.headers['access-control-request-headers']);

        oneof = true;

      }

      if(oneof) {

        res.header('Access-Control-Max-Age', 60 * 60 * 24 * 365);

      }

    // intercept OPTIONS method

    if (oneof && req.method == 'OPTIONS') {

      res.send(200);

    } else {

      next();

    }

    }



    app.use(allow_cross_domain);



    app.post('/auth/signup', function (req, res) { res.send('wtff'); });

I'm just calling POST localhost:3000/auth/signup from Angular to Node, but i get **CAUTION : Provisional headers are shown.** in chrome console.

Chrome (CAUTION):

Firefox (NO RESPONSE for about 30/60 seconds and then the alert() comes up :/ ):

what this could be?

IF i use GET everything is ok, is just with POST that i get troubles how is that possible?
