Overview
Flush Opcache with Varnish automatically flushes the PHP Opcache when one of the “Empty Cache” buttons that Mika Epstein’s excellent Varnish HTTP Cache creates are clicked.
If the WP Opcache plugin is installed it is used to flush the opcache to let the opcache be re-warmed according to your WP Opcache settings, (and you can turn off WP Opcache’s “Flush PHP Opcache” button from the Admin toolbar).
If WP Super Cache is installed then the WP Super Cache cache will be cleared as well.
