Is there a way to invalidate a cached item on multiple varnish servers at once?

[Rainer Duffner]

Hi,

suppose you've got a couple of load-balanced varnish-servers, is there a way to have an item removed from the cache on multiple servers at the same time?

Seeing that e.g. drupal has no way to specify more than one varnish server, I assume it would have got to be some sort of proxy.

Or is this only in the commercial product?
