[squid-users] problem to configure reverse proxy

Bonjour,

I'm stuck with a reverse proxy config.

I have one http server with 5 sites (http) and 2 https, 1 OWA & RPC
server which also serves logos on port 80.

What I want to do :

(I'm bad at ASCII art, but i give it a try :)

WWW ---- iptables/DNAT --- SQUID --- http 1
                       --- http 2 ...
                       --- https 1 --- http (acl A_gi)
                       --- https 2
                       --- OWA

I wrote this config file, and http seem's OK, but i don't understand
the way https works. I follow the doc at :
http://wiki.squid-cache.org/ConfigExamples/Reverse/SslWithWildcardCertifiate
but it give 1 certificate for 2 sites, and thus the certificat is not
valid when i access the sites.

In the graphic, https 1 has a page with a frame which contains a page
in an other server which is accessed with http (not s).

Thank you for any help.
