Global Ajax error handler with AngularJS

I’m also building a website with angular and I came across this same obstacle for global 401 handling. I ended up using http interceptor when I came across this blog post. Maybe you’ll find it as helpful as I did.

“Authentication in AngularJS (or similar) based application.”, espeo software

EDIT: final solution

angular.module('myApp', ['myApp.filters', 'myApp.services', 'myApp.directives'], function ($routeProvider, $locationProvider, $httpProvider) {

    var interceptor = ['$rootScope', '$q', function (scope, $q) {

        function success(response) {
            return response;
        }

        function error(response) {
            var status = response.status;

            if (status == 401) {
                window.location = "./index.html";
                return;
            }
            // otherwise
            return $q.reject(response);

        }

        return function (promise) {
            return promise.then(success, error);
        }

    }];
    $httpProvider.responseInterceptors.push(interceptor);
