In templates sometimes you need to display some menu by checking whether the user is logged in or not. So use the above filter as shown below

{% with request|check_login as logout %}
{% if logout%}
display something....
{% endif %}
{% endwith %}

<p>Can't you just do something like this:</p> <pre>{% if request.user.is_authenticated %} display something {% endif %} </pre>
