Like this:

app.factory('redirectInterceptor', ['$q', '$rootScope', function($q, $rootScope) {
    return function(promise) {
        promise.then(
            function(response) {
                return response;
            },
            function(response) {
                switch(response.status){
                    case 401:
                        $rootScope.logout();
                        break;

                    case 403:
                        $rootScope.logout();
                        break;

                    default:
                        var x;
                }
                return $q.reject(response);
            }
        );
        return promise;
    };
}]);
