Hi all,

I just saw the new Varnish HA 
video<https://www.youtube.com/watch?v=KhqVdKe2RAU> and was wondering if VHA's 
node synchronization would obviate the need for all of the Varnish nodes to be 
listed in the MediaWiki Varnish caching 
configuration<https://www.mediawiki.org/wiki/Manual:Varnish_caching>. MediaWiki 
uses the list of cache nodes to send HTTP PURGE requests to invalidate cached 
pages when they are updated. So with VHA, could MediaWiki just be configured 
with a single hostname or floating IP address (e.g. keepalived) that points to 
the Varnish cluster so that the cluster could handle replicating the PURGE 
requests?

Thanks,
Justin
