New Post: Enabled
Updated Post: Enabled
If you are using the Free Downloads Extension, please enable the ‘Mobile’ checkbox, as this will prevent your mobile users from being shown the desktop version of the free downloads form.
Add rules to the Exclude section for:
Your checkout page. By default this is `checkout`
Purchase Confirmation page. By default these URLs contain the `purchase-confirmation` slug.
Note: If you have renamed the default checkout, purchase confirmation, or purchase history pages, you’ll need to use their page URLs here instead of the defaults.
In order for EDD’s cart to work you’ll need to exclude the `edd_items_in_cart` cookie.
To make sure that cart errors are not cached, exclude this cookie `edd_cart_messages`
Once a purchase is complete, make sure the purchase confirmation isn’t cached by excluding the `edd_purchase` cookie.
If your site uses fees in anyway, exclude the `edd_cart_fees` cookie.
In order to support cart recovery, exclude the `edd_resume_payment` cookie.
Make sure the cart itself isn’t cached by excluding the `edd_cart` cookie.
If you are using discounts, be sure to exclude the `cart_discounts` and `preset_discount` cookies.

If you are hosting your website with WP Engine you can add Custom Cache Exclusions using your administration panel.
WP Engine provides a documentation article https://wpengine.com/support/cache/#Custom_Cache_Exclusions on how to exclude items from cache.
In some cases when passing the “discount” parameter in the URL the discount code is not being added to the Checkout page once the customer reaches it. For that to work you need to add the “discount” argument as an exclusion following the steps listed in the article above.
It would need to be added in the format: arg: discount=
Following the same example you can add other arguments from being excluded from their caching.
For users hosting with Kinsta, it is possible that the Checkout page session data to be cached. The way to fix it is from your hosting account Tools panel by enabling “Remove Set-Cookie headers”.
