I really hope this is finally an answer for our, and many other's cart66's sites.
Currently, we simply show the cart66's cart widget via a sidebar call:
<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar(2) ) : endif; ?>
Is there any way to prevent caching of that sidebar? Or a better alternative to call it that is compatible with your plugin?
The store's pages are also domain.com/store/cart domain.com/store/checkout etc. Is there a way to disable cashing on all /store/ pages?
I'm really excited about the prospects of this plugin.
