I have the following code in an external file(same domain) to get the current cart details, and I'm getting all details without any issues.

The problem is, when I go to the checkout page using 'Go to checkout' and press browser back button this cart gets empty. I mean only on this external file.

When I click the 'view and edit cart' and uses the browser back button the cart is fine.

Any help would be appreciated!
