        // (e.g. http://domain.com/#/en/123)
        //
        // The reason is that linking an article from Newscoop (Symphony
        // framework) with an URL containing stuff after '#' creates all sorts
        // of problems on the backend (e.g. Symphony stripping the part after
        // the '#' character), making it much more complicated to use such
        // URLs in a Newscoop plugin. It was thus decided that a global
        // object containing article info would be provided and Angular will
        // then make sure that user gets redirected to the correct article
        // (with URL now containing the necessary part after '#').
