My shopping cart is being cached by w3 total cache. This is the expected default behaviour. The thing is I can't find an easy solution for this.
I am showing my shopping cart on almost every page, so using rejected cookies or something similar is not an option. Is it possible to tell w3 total cache not to cache a single php file like cart_widget.php? Or some other workaround?
I know there is the possibility to load the cart via ajax as the plugin does not cache GET requests with parameters (by default). Still, I would like to avoid that extra request.
EDIT: Also, w3 total cache is not regenerating the page when I edit the product, is there an easy way to tell w3 total cache to empty the cache for a single page?
