Having an issue with an inherited install of squid 2.7 running on Windows, acting as a reverse proxy to an IIS box with multiple sites on it. The squid is in our DMZ (pokes for 8085 and 8086 are in place), IIS is internal. The problem I'm seeing is that squid is returning the content on port 8085 irrelevant of whether I'm coming in on 8085 or 8086. I've spent a full day reading up on squid and searching around for more info, and have come up with squat. Any suggestions on what I've done wrong (probably with the cache_peer) would be welcome! So, thanks in advance for helping out! squid.conf is below. -~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~ #NETWORK http_port 8085 transparent http_port 8086 transparent #Cache_MEM memory_replacement_policy lru cache_mem 512 MB maximum_object_size_in_memory 4096 kb #Cache_DISK memory_replacement_policy lru cache_dir ufs c:/squid/var/cache 512 16 256 maximum_object_size 8192 KB #Cache tuning"ignore-no-cache" ignores the no cache header from AutoUpdate refresh_pattern . 90 100% 180 reload-into-ims ignore-no-cache #refresh_pattern . 90 100% 180 ignore-reload #LOGGING cache_store_log none cache_log c:/squid/var/logs/cachelog.txt access_log c:/squid/var/logs/access.txt squid #ADMINISTRATIVE #visible_hostname <ipaddress of squid system> <FQDN alias> <short name> visible_hostname SQUID.INTERNAL.IP SQUID.EXTERNAL.HOSTNAME SQUID.WINDOWS.HOSTNAME unique_hostname SQUID.WINDOWS.HOSTNAME #OPTIONS FOR AUTHENTICATION acl all src 0.0.0.0/0.0.0.0 acl protocol proto HTTP acl safe_ports port 8085 acl safe_ports port 8086 acl getonly method GET http_access allow all #Neighbor select Algorithm #cache_peer <address of IIS system> <type> <listening port> <icp_port> no-query originserver name=Accesslist cache_peer IIS.SERVER.IP parent 8085 0 no-query originserver name=MyAccessList cache_peer IIS.SERVER.IP parent 8086 0 no-query originserver name=MyAccessList2 cache_peer_access MyAccessList allow all cache_peer_access MyAccessList2 allow all cache_peer_access MyAccessList deny !protocol cache_peer_access MyAccessList2 deny !protocol cache_peer_access MyAccessList deny !safe_ports cache_peer_access MyAccessList2 deny !safe_ports cache_peer_access MyAccessList deny !getonly cache_peer_access MyAccessList2 deny !getonly -~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~
