You either use HTTP PURGE against Varnish or issue a ban. See the tutorial

Also, from what I understand varnish doesn't support clustering.  What if

You can either use Varnish as a load balancer (it is rather good at load
balancing) use the hash director or any other load balancer  that supports
"URL target" hashing.
