By default your HTTP requests with the $https service in Angular are not cached. By setting some options, you can turn caching on.

angular.module('app', ['ngMaterial'])
    .controller('MainCtrl', function(BookmarksService, BookmarksCacheFactory) {
        var mainCtrl = this;
        mainCtrl.bookmarks = [];

        mainCtrl.getBookmarks = function() {
            BookmarksService.getBookmarks().then(function(response) {
                mainCtrl.bookmarks = response.data;
            });
        }

        mainCtrl.removeCache = function() {
            BookmarksCacheFactory.remove('./data/bookmarks.json');
        }
    })


    .service('BookmarksService', function($http, BookmarksCacheFactory) {
        var BookmarksService = {};

        BookmarksService.getBookmarks = function() {
            return $http.get('./data/bookmarks.json', {cache: BookmarksCacheFactory});
        }

        return BookmarksService;
    })


    .factory('BookmarksCacheFactory', function($cacheFactory) {
        return $cacheFactory('bookmarks');
    });
