UPGRADE FROM 2.1 to 2.2 TwigBridge

``` html
<div id="sidebar">
    {% render url('latest_articles', { 'max': 3 }) %}
</div>
```

If I upgrade symfony to 2.2 for all embedded controller actions I must create routes. This means that I can access to these controller actions with url if url match route pattern. What can I do if I only want to use these routes only for embedding?
e.g. Controller action that render some menu
