the same code working old version of chrome i.e, v29...* . updated chrome v30...* . now, not working. not working in firefox well. there problem chrome , firefox?

can help?

i came across similar issue after updating chrome version 30.0.1599.101 , turned out server problem.

my server implemented using express (http://expressjs.com/) , code below allowing cors (how allow cors?) works well:

var express = require("express"); var server = express();  var allowcrossdomain = function(req, res, next) {     res.header('access-control-allow-origin', req.headers.origin || "*");     res.header('access-control-allow-methods', 'get,post,put,head,delete,options');     res.header('access-control-allow-headers', 'content-type,x-requested-with');     next(); } server.configure(function () {     server.use(allowcrossdomain); });  server.options('/*', function(req, res){     res.header('access-control-allow-origin', req.headers.origin || "*");     res.header('access-control-allow-methods', 'get,post,put,head,delete,options');     res.header('access-control-allow-headers', 'content-type,x-requested-with');     res.send(200); });  server.post('/some_service', function (req, res) {   res.header('access-control-allow-origin', req.headers.origin);    // stuff here    //example of json response   res.contenttype('json');   res.send(json.stringify({ok: true})); }); 

the http request looks like:

$http({     method: 'post',     url: 'http://localhost/some_service',     data: json.stringify({         key1: "val1",         key2: "val2"     }),     headers: {         'content-type': 'application/json; charset=utf-8'     } }).success(     function (data, status, headers, config) {         //do     } ).error(     function (data, status, headers, config) {         //do     } ); 

as pointed out in here (https://stackoverflow.com/a/8572637/772020), idea ensure server handles options request in order enable cors.
