Magento Footer Behavior

Question

I just notice that when ever I add this codes on the Magento Footer:

$current_id = Mage::registry('current_category')->getId();
echo $current_id;

The Category ID is not changing whenever I change the Category. It only changes when I clear the cache.

It is possible that the Magento Footer is a Static One? Cause I won't update unless you clear any cache.

Answer 1

You can set the cache lifetime value from XML

<reference name="footer">
    <action method="setCacheLifetime"><s>null</s></action>
</reference>

or

<reference name="footer">
    <action method="setCacheLifetime" />
</reference>
