I was doing something similar.

Browser --SSL-> Squid3 --SSL--> OWA 2003

I am able to authenticate to Exchange. I see the Userid-Password Box. that
But then the OWA Site cannot be displayed.

wath's wrong?

Thank you very much indeed.

This is my config:

visible_hostname squidhost
cache_mgr mail@mail.com

cache_effective_user squid

https_port 443 cert=/usr/local/squid/etc/exchange.crt
cafile=/usr/local/squid/etc/exchange.crt defaultsite=exchangeserver/exchange

cache_peer exchangeserver parent 443 0 no-query ssl proxy-only originserver
login=PASS sslcert=/usr/local/squid/etc/exchange.crt
sslkey=/usr/local/squid/etc/exchange.key sslflags=DONT_VERIFY_PEER
front-end-https=on sslversion=1

ssl_unclean_shutdown on

acl owa-exchange urlpath_regex \/exchange(\/|$)
acl owa-webid urlpath_regex \/WebID\/

acl all src
acl all-dst dst
acl owa-host dst IP-exchangeserver/

http_access allow owa-host owa-exchange
http_access allow owa-host owa-webid
http_reply_access allow all-dst
http_access deny all
http_access deny all-dst
