[squid-users] SQUID3 + Reverse proxy + OWA: strange error

Hi all,

I'm trying to setup a squid3 to do reverse proxy for OWA running on Exchange 2000 but I can't success: (I have read all posts about OWA + squid but unable to find a clue...)

Here is my setup

---------- ------------- ----------------
- CLIENT - ==> :443 - SQUID3 - ==> :80 - OWA@exch2000 -
---------- ------------- ----------------

When I go to http://webmail.xxx.fr/exchange/ it works, auth + browsing etc ...

When I go to https://webmail.xxx.fr/exchange the auth box comes (I use basic auth on OWA), I put my login and password, then the 2 frames of the OWA web site appear but they are blank. When I go to my log files (exchange) I can't find the problem.

 Here is my setup for squid:

cache_peer webmail.xxx.fr parent 80 0 no-query originserver login=PASS front-end-https=auto proxy-only

Here is a sample of my access.log during an unsuccess attempt
_____________________________

4 172.21.1.4 TCP_MISS/401 333 GET https://webmail.xxx.fr/exchange/ - FIRST_UP_PARENT/webmail.xxx.fr text/html
19 172.21.1.4 TCP_MISS/200 1518 GET https://webmail.xxx.fr/exchange/ - FIRST_UP_PARENT/webmail.xxx.fr text/html

==> When I run squid in console mode (squid -d1 -N), I see that an error occur, but after googling and browsing the squid-archive-list I can't find out why: "ClientNegotiateSSL: Error negotiating SSL connection on FD 16"

I have a second question: I want that squid serves https://www.xxx.fr on a host, and https://www.xxx.fr/exchange/ or https://webmail.xxx.fr or https://webmail.xxx.fr/exchange/ on a second host ==> it is possible to do that with squid? And if yes, how ?

Any help would be greatly appreciated. Thanks a lot.
