It's a component method. There are 2 methods that are called for each
component, both receiving the controller as a parameter.
initialize: Called before the Controller::beforeFilter().
startup: Called after the Controller::beforeFilter() and before the
controller action
http://api.cakephp.org/class/component
So, the example I posted earlier shows how to maintain a handle on the
controller so as to call its methods.

But requestAction() is a horrible performance hog so hopefully you'll
get all of this sorted out enough where you no longer (think you) need
it.

What the heck is this?!
echo "<?php $product_id = $product_id; ?>"; ?>
I think you should maybe consider not caching this view. That might be simplest.

If it's academic, I'm afraid I'd have to give you a D. Your
interpretation of how view caching *should* work is not realistic.
