Sorry for not including enough informatio nin the first place. 1. Here's my config, keep in mind it's a test server that will eventually replace the one (not updated) we're using right now so the configuration is kinda bare-bones: ### TESTSQUID1 ### http_port 3128 dns_v4_first on pinger_enable off netdb_filename none error_default_language it cache_mgr helpdesk@xxxxxxx acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT auth_param negotiate program /usr/lib/squid/negotiate_kerberos_auth -r -d auth_param negotiate children 150 auth_param negotiate keep_alive on external_acl_type ProxyUser children-max=75 %LOGIN /usr/lib/squid/ext_kerberos_ldap_group_acl -g INTERNET@TEST.LOCAL -D TEST.LOCAL -S testldap acl ProxyUser external ProxyUser acl AUTH proxy_auth REQUIRED http_access deny !AUTH all http_access deny !Safe_ports all http_access deny CONNECT !SSL_ports all http_access allow localhost manager http_access deny manager all http_access allow localhost all acl destsquid dstdomain .testquid1 .testsquid2 http_access allow destsquid all http_access allow ProxyUser all http_access deny all icap_enable on icap_send_client_ip on icap_send_client_username on icap_client_username_encode off icap_client_username_header X-Authenticated-User icap_preview_enable on icap_preview_size 1024 icap_service service_req reqmod_precache bypass=1 icap://testicap:1344/REQ-Service adaptation_access service_req allow all icap_service service_resp respmod_precache bypass=0 icap://testicap:1344/resp adaptation_access service_resp allow all coredump_dir /var/spool/squid refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 2.

The result of the test at redbot (https://redbot.org/?uri=http%3A%2F%2Fwww.tomshardware.com%2F if you want to check it yourself) is: General The Pragma header is deprecated. The Content-Length header is correct. Content Negotiation (Content Negotiation response ) The resource doesn't send Vary consistently. The response body is different when content negotiation happens. Content negotiation for gzip compression is supported, saving 86%. Caching Pragma: no-cache is a request directive, not a response directive. This response can't be stored by a cache. So it indeed seems that this could be the problem, right? Anything I can do on my end to resolve/mitigate it?
