    // for e.g. a Link button ("make me admin") that is disabled this is a security breach.
    // - solution b needs some wrapping, the advantage (for images) would be that they are cached by the browser if requested more than once
    // within a controller
    // - solution c is a safe and easy way to allow dispatching (only in case a mediaresource is returned as a result of the dispatching) even
