Proper Pound/Varnish set-up?

[Jarry]

Hi,

I'm quite new to varnish and http(s) caching, but I'd like to set up
caching for my apache webserver (running a few web-sites with Drupal).
I searched google for some info and found basically two possibilities:
_____________________________________

A): Varnish listening on the port 80/http (caching Apache, running on
8080), and Pound listening only on the port 443/https (after https-
termination forwarding traffic to Varnish).

-> Varnish(public_IP:80) -> Apache(lo:8080)
       ^
       |
-> Pound(public_IP:443)
_____________________________________

B): Pound listening on both 80/http and 443/https ports. Both http
(directly) and https (after termination) traffic is forwarded to
Varnish, and further to Apache.

-> Pound(public_IP:80,443) -> Varnish(lo:8008) -> Apache(lo:8080)
_____________________________________

I tested both of these configurations, both of them seem to work
(sort of, there are certain specific problems with both set-ups).
But I still can not decide: which set-up is better, and why?
