Hi. I have a WordPress multisite which works in several servers (in fact, it's an autoscaling platform hosted at Amazon Web Services). I would like that whenever I delete the cache of one site (by the direct button or when I update a post), all the cache files across all the servers be deleted too. So I would like to know if there is an specific action or filter inside WP Super Cache which I could use to achieve this. Or maybe there is already a plugin which does this.
