How to configure caching plugins for WooCommerce

https://wordpress.org/support/topic/excluding-woocommerce-cookies-from-the-cache/

these suggest skipping wp_woocommerce_session_ in cache

WooCommerce Window Shopping Caching Technique

but ee only uses unique session ids for that cookie

The EasyEngine approach is what SlickStack also implements, some GitHub users have also used the same approach too. But a few Discord users have complained about conflicts with some WooCommerce add-ons having cache conflicts on the thankyou/order-received page…

e.g. https://gist.github.com/edisoncosta/6d512411921771b38dd8

^^what SlickStack does

Today we also added store_notice.* and woocommerce_recently_viewed

Note these are only for the “Recent viewed products” widget and store notices in Woo, which are not commonly used, but good to skip anyways:
