Squid since 2.6 are erfectly capable of caching dynamic content correctly provided you add the refresh_pattern rule for (/cgi-bin/|\?) in the right place. > cache_mem 2000 MB > maximum_object_size_in_memory 32 KB > memory_replacement_policy heap GDSF > cache_replacement_policy heap LFUDA > cache_dir ufs /var/squid/cache 500 16 256 > minimum_object_size 0 KB > maximum_object_size 4 KB > offline_mode offcache_swap_low 90 > cache_swap_high 95 > > # No redirector configured > > > #Remote proxies > > > # Setup some default acls > acl allsrc src all > acl localhost src 127.0.0.1/32 > acl safeports port 21 70 80 210 280 443 488 563 591 631 777 901 3128 > 1025-65535 > acl sslports port 443 563 > acl manager proto cache_object > acl purge method PURGE > acl connect method CONNECT > > # Define protocols used for redirects > acl HTTP proto HTTP > acl HTTPS proto HTTPS > > http_access allow manager localhost > > http_access deny manager > http_access allow purge localhost > http_access deny purge > http_access deny !safeports > http_access deny CONNECT !sslports > > # Always allow localhost connections > http_access allow localhost > > quick_abort_min 0 KB > quick_abort_max 0 KB All of these... > request_body_max_size 0 KB > delay_pools 1 > delay_class 1 2 > delay_parameters 1 -1/-1 -1/-1 > delay_initial_bucket_level 100 > # Throttle extensions matched in the url > acl throttle_exts urlpath_regex -i "/var/squid/acl/throttle_exts.acl" > delay_access 1 allow throttle_exts > delay_access 1 deny allsrc ... do nothing. Except, the delay_pools still involve 32-bit limits so may also be your issue if it is 32-bit related. > > # Reverse Proxy settings > http_port 75.145.82.58:80 accel defaultsite=deeztek.com vhost > https_port 75.145.82.58:443 accel > cert=/usr/pbi/squid-i386/etc/squid/53dfccd7cbb37.crt > key=/usr/pbi/squid-i386/etc/squid/53dfccd7cbb37.key > defaultsite=deeztek.com vhost > # > cache_peer 10.10.14.254 parent 443 0 proxy-only no-query no-digest > originserver login=PASS round-robin ssl sslflags=DONT_VERIFY_PEER > front-end-https=auto name=rvp_webserver.deeztek.com > > # > cache_peer 10.10.14.201 parent 443 0 proxy-only no-query no-digest > originserver login=PASS round-robin ssl sslflags=DONT_VERIFY_PEER > front-end-https=auto name=rvp_owa.deeztek.com > > # > cache_peer 10.10.14.251 parent 458 0 proxy-only no-query no-digest > originserver login=PASS round-robin ssl sslflags=DONT_VERIFY_PEER > front-end-https=auto name=rvp_cloud.deeztek.com > > # > cache_peer 10.10.14.238 parent 443 0 proxy-only no-query no-digest > originserver login=PASS round-robin ssl sslflags=DONT_VERIFY_PEER > front-end-https=auto name=rvp_ewa.deeztek.com > > # > cache_peer 10.10.14.250 parent 443 0 proxy-only no-query no-digest > originserver login=PASS round-robin ssl sslflags=DONT_VERIFY_PEER > front-end-https=auto name=rvp_mail.deeztek.com > > # > cache_peer 10.10.14.254 parent 80 0 proxy-only no-query no-digest > originserver login=PASS round-robin name=rvp_admin.grubbcontractors.com > Note that "round-robin" peer selection does not exactly jive well with explicit cache_peer_access restricting each peer to only accepting certain domains traffic. The access rules make each round-robin group a set of 1 peer.

Example: acl rvm_grubbcontractors.com dstdomain grubbcontractors.com 2) add HTTP/HTTPS ACL test to the cache_peer_access below ... - for each peer which is required to accept HTTPS-only start its rule list with: cache_peer_access ... deny !HTTPS - for each peer which is required to accept HTTP-only start its rule list with: cache_peer_access ... deny !HTTP > cache_peer_access rvp_webserver.deeztek.com allow rvm_deeztek.com > cache_peer_access rvp_owa.deeztek.com allow rvm_OWASSL > cache_peer_access rvp_ewa.deeztek.com allow rvm_EWASSL > cache_peer_access rvp_mail.deeztek.com allow rvm_MAILSSL > cache_peer_access rvp_webserver.deeztek.com allow rvm_visionexperts.com > cache_peer_access rvp_webserver.deeztek.com allow rvm_grubbcontractors.com > cache_peer_access rvp_admin.grubbcontractors.com allow > rvm_admin.grubbcontractors.com > cache_peer_access rvp_webserver.deeztek.com deny allsrc > cache_peer_access rvp_owa.deeztek.com deny allsrc > cache_peer_access rvp_ewa.deeztek.com deny allsrc > cache_peer_access rvp_mail.deeztek.com deny allsrc > cache_peer_access rvp_webserver.deeztek.com deny allsrc > cache_peer_access rvp_webserver.deeztek.com deny allsrc > cache_peer_access rvp_admin.grubbcontractors.com deny allsrc Also, you may as well remove the "allsrc" from the above lines. No error page is generated directly by these access controls. The default "cannot connect" will be if none are selected. Just use "all" here instead. It may help you manage what peer is doing what by grouping the rules for each peer together in a sequential bunch. > never_direct allow rvm_deeztek.com > never_direct allow rvm_OWASSL > never_direct allow rvm_EWASSL > never_direct allow rvm_MAILSSL > never_direct allow rvm_visionexperts.com > never_direct allow rvm_grubbcontractors.com > never_direct allow rvm_admin.grubbcontractors.com > http_access allow rvm_deeztek.com > http_access allow rvm_OWASSL > http_access allow rvm_EWASSL > http_access allow rvm_MAILSSL > http_access allow rvm_visionexperts.com > http_access allow rvm_grubbcontractors.com > http_access allow rvm_admin.grubbcontractors.com > > deny_info TCP_RESET allsrc > > # Custom options > > > # Setup allowed acls > # Allow local network(s) on interface(s) > http_access allow localnet > # Default block all to be sure > http_access deny allsrc > > ====== squid.conf ends above ======== > HTH Amos
