So a page such as this
https://domain.com/154/index.php?mai...products_id=12


has a rel="canonical" of this

<link rel="canonical" href="https://domain.com/154/index.php?main_page=product_info&amp;products_id=12" />

Which forces a redirect for tools such as OpenGraph, Google Shopping etc who read and respect the canonical attribute.

I see where it can be changed in init_canonical.php

$includeCPath = TRUE;

However, I would rather think TRUE should be default and not the other way around.
