auth managers expose isTokenValid method - if you are using grails REST spring security will call the validate token endpoint (requires, 1.4.0.RC5+ of the grails rest spring security plugin)

because of this checkRequest now takes a $http parameter

``` app.js - when configuring the run.app section
// run blocks
myApp.run(['$rootScope', '$cookieStore', '$location', '$cookies', 'avLogin', '$http',
    function($rootScope, $cookieStore, $location, $cookies, avLogin, $http) {
        /* Try getting valid user from cookie or go to login page */
        avLogin.checkRequest($location, $cookieStore, $cookies, $rootScope, $http);
    }
]);
