I am testing with Squid 3 Stable 13 on CentOS 5, reverse proxy to Exchange 2010 and seeing very slow page on the main OWA page. When I access OWA, the initial login page loads very quickly, then I click "Sign In." The next screen takes 4-5 mins to finish loading. I sat there and timed it... If I hit refresh 3-4 times, the page loads completely. Once the OWA main page fully loads, browsing is normal. If I close my browser and login in OWA again, speeds are normal. If I clear my browser's cache, the problem returns. The issue does not happen if I directly connect to OWA. I searched the archive email and saw someone with the same exact issue, but there were no replies. Originally I had Squid 2.6 stable 21, then I upgraded to 3 Stable 13, hoping that would address the issue, but it did not. Thanks for your time and help. -- Here is my config: visible_hostname devlinux1.domain.net extension_methods RPC_IN_DATA RPC_OUT_DATA https_port 443 cert=/etc/pki/cert/owa_domain_com.crt key=/etc/pki/cert/owa_domain_com.key defaultsite=owa.domain.com cache_peer 192.168.179.235 parent 443 0 no-query originserver login=PASS ssl sslflags=DONT_VERIFY_PEER front-end-https=on name=owaserver acl all src 0.0.0.0/0.0.0.0 acl owa dstdomain owa.domain.com cache_peer_access owaserver allow owa never_direct allow owa http_access allow owa http_access deny all miss_access allow owa miss_access deny all cache_mem 256 MB cache_dir ufs /var/spool/squid 1000 16 256 #maximum_object_size_in_memory 256 KB minimum_object_size 0 KB maximum_object_size 32 MB
