thanks for this answer but as you said it's useful only in these cases:
If the cart is display on all pages, If you have a HikaShop system plugin which load HikaShop on every pages
for all other cases it's not only useless, it's nocive for the website's speed.
In my case for example Hikashop is used only on Hikashop pages, wich represents 20% of my site. So I can't afford to make heavier 80% pages of my site uselessly. I really need to know please how I can remove these scripts from my other pages please?
or saying other: how can I load these scripts only when they're needed?
in advance thanks for your answer
