ah hmm actually this is not possible in this case since the varnish
servers are used in front of shared hosting for a couple of select sites
and we don't really control the contents of the sites.

Guillaume's suggestion of using varnishncsa is a possibility that I can
explore.

While brainstorming with co-workers, we've had another idea too: since
we're serving error pages as static html on one special backend we could
inject a header in the request made to that server to identify the
backend used in the original client request and thus count errors per
backend.
