See Thread at: http://www.techienuggets.com/Detail?tx=58290 Posted on behalf of a User 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 Address: 213.205.32.10 Non-authoritative answer: Name: mail.telecomitalia.it Addresses: 156.54.233.103, 156.54.233.102 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. Lodovico Bertolini In Response To: 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 10.1.103.104 TCP_MISS/200 3088 CONNECT OBFUSCATED_URL:443 - DIRECT/84.14.218.217 - 1225194825.050 118 10.1.103.104 TCP_MISS/200 1056 CONNECT OBFUSCATED_URL:443 - DIRECT/84.14.218.217 - 1225194825.185 133 10.1.103.104 TCP_MISS/200 4524 CONNECT OBFUSCATED_URL:443 - DIRECT/84.14.218.217 - 1225194825.367 168 10.1.103.104 TCP_MISS/200 2371 CONNECT OBFUSCATED_URL:443 - DIRECT/84.14.218.217 - 1225194849.719 24520 10.1.103.104 TCP_MISS/200 155 CONNECT OBFUSCATED_URL:443 - DIRECT/84.14.218.217 - 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. Momo
