Hello! I have started building simple Todo app in **Ionic 1** and I discovered a problem with Origin header. (CORS related) If i run `ionic serve` everything works fine in browser and i can make requests to my REST API on apache(tomcat). But when build my app for android or even in ionic viewer, all requests fail. Using a chrome debugger I managed to locate the problem. Native app sends header `Origin: file://` which causes my server to deny requests. Seems to me that it should send correct Origin header with host. Screenshot with more details is attached below. ![image](https://global.discourse-cdn.com/ionicframework/original/3X/f/2/f2e8fe6ab26641372eed4b54b3e7068d8e8eded2.png) What can I do about that? Found related topic here: [http://stackoverflow.com/questions/25914071/cors-cordova-angularjs-http-and-file-confusion](http://stackoverflow.com/questions/25914071/cors-cordova-angularjs-http-and-file-confusion) **EDIT:** Problem occurs when post, if I run ionic starter (tabs) template with only `$http.post('http://myapp.com/apiv1/device')` added to controller.
