I think there is something wrong in this OWA server setup:
Check with nslookup if OWA2007 have round robin active:

C:\>nslookup mail.telecomitalia.it
Server: dns1.tiscaliia.it

Non-authoritative answer:
Name: mail.telecomitalia.it

If is active like my example use thi in your squid configuration (squid.conf):
balance_on_multiple_ip off

A round robin configuration for a OWA front-end is a wrong
solution because OWA is a session based web application.

Hi folks,

I'm experiencing some trouble to acces an OWA 2007 server, located
behing an ISA reverse proxy, through our Squid 2.6ST18 proxy.

When I try to access it, IE or Firefox keeps waiting for data to
tranfer, the page stays blank and it nevers falls nor on time-out or
any other error.

Squid log shows lines that let think that there is some traffic transferred:

1225194824.927 1042 TCP_MISS/200 3088 CONNECT
1225194825.050 118 TCP_MISS/200 1056 CONNECT
1225194825.185 133 TCP_MISS/200 4524 CONNECT
1225194825.367 168 TCP_MISS/200 2371 CONNECT
1225194849.719 24520 TCP_MISS/200 155 CONNECT

Direct connexion (I mean bypassing our Squid proxy) to this website works fine.

As i had a similar problem some time ago on another OWA installation,
I tried to deactivate "Accept-Encoding" header in Squid Proxy but it
is the same problem.
Our Squid Installation is quite basic, we don't authenticate our
clients, only a small cache is done on the fly.

For those who would give a try, I pasted the URL at
http://pastebin.com/m44904a19 to prevent it from showing up in mailing
lists archives, as this server belongs to a partner.
Please do not paste it in your replies.

Thanks for any help.
