The multi-language plugin WPML adds the cookie called “wp-wpml_current_language” for non-login users to support AJAX filtering. This cookie makes the users bypass the APO cache (Automatic Platform Optimization) because of the name “wp-” part. The first page load without the cookie can hit the cache, but the second load is always bypassed.
Could you consider adding support for this plugin? Thank you!
wp-wpml_current_language – Stores the current language. By default, this cookie is set only for logged-in users. If you enable the language cookie to support AJAX filtering, this cookie will also be set for users who are not logged in.
