How can I output HTML in a template without it being passed through a caching filter? [closed]

by

Got it to work:

In wp-config.php I added:

define('W3TC_DYNAMIC_SECURITY', 'mysecretcode');

I created a PHP file (nocache.php) containing just the HTML to be output, and put it in the root folder. Then in my template file I used:

<!-- mclude mysecretcode nocache.php --><!-- /mclude mysecretcode -->
