Actually, for protocol purposes, Varnish is an origin server.

If you read RFC2616 very carefully, you can find the one place where
they failed to evict server-side caches from the text, when they
realized that a cache under the control of the webmaster, is
indistinguisable from a webserver, for protocol purposes.

Never attribute to malice what can adequately be explained by incompetence.
