This is a snippet to implement a global interceptor used to handle 403 errors for example From http://stackoverflow.com/questions/17687804/handling-http-get-and-http-post-errors-in-angularjs

angular-global-http-error-handler.js

angular.module('services')
    .config(function($httpProvider){
        //Here we're adding our interceptor.
        $httpProvider.responseInterceptors.push('globalInterceptor');
    })
    //Here we define our interceptor
    .factory('globalInterceptor', function($q){
        //When the interceptor runs, it is passed a promise object
        return function(promise){

            //In an interceptor, we return another promise created by the .then function.
            return promise.then(function(response){
                //Do your code here if the response was successful

                //Always be sure to return a response for your application code to react to as well
                return response;
            }, function(response){
                //Do your error handling code here if the response was unsuccessful

                //Be sure to return a reject if you cannot recover from the error somehow.
                //This way, the consumer of the $http request will know its an error as well
                return $q.reject(response);
            });
        }
    });
