Hello Marc,
thanks for your answer! That´s very good to know, cause we´re using BuddyPress and we need the toolbar. If we find any issues, will use this bug report, too.
Can I ask you one question more, please? Makes it sense to combine HHVM with Apache as gateway to send request to fastcgi, varnish at the front for full page cache and nginx as proxy and static content handler ? In this case W3TC just for database-cache and object cache with APC ?
Thank you!
Best regards
