That's one way.

Four other ways:

  - Use Apache's mod_cache stuff instead of Varnish (as you mentioned).

  - Don't run repoze.zope2 under Apache and instead run it under paster serve and
    proxy from Apache thru Varnish.

  - Run two Apache instances:

              Apache (80)
                  |
                  | mod_proxy
                  v
             Varnish (8888)
                  |
                  | http
                  v
                Apache (mod_wsgi)

  - Don't use Apache or varnish, and instead use Squid to both do the caching
    and the reverse proxying via its redirector setup.
