Ok, this issue appears on certain (e.g. carsoup.com, ebay.com, wsca.org) sites when Squid is sending the request to DansGuardian. I can access the sites if I put them in my "always_direct" directive. The actual 400 error is "page cannot be found". Anyone have any ideas? Below is a copy of my squid.conf.
Many thanks!! Scott ____________________________________________________________________________ ___________ Ok, here is my squid.conf.mlist. I think this issue only happens when squid forwards the requests to DansGuardian. When I put the concerned domains in the "always_direct" directive they work fine. Here is my set up: Client ----> Squid ----> DG ----> Mcafee Webshield ----> Internet 99.9% of the sites work just fine, except a few. DG is a new implementation I am working on to replace all the blocking ACLs I have in squid. Do you see anything in this config that could cause this? http_port 3128 cache_peer e500b parent 80 0 no-query weight=10 cache_peer e500c parent 80 0 no-query weight=9 cache_peer 127.0.0.1 parent 8080 0 no-query acl QUERY urlpath_regex cgi-bin \? no_cache deny QUERY cache_mem 256 MB cache_swap_low 90 cache_swap_high 95 maximum_object_size 12 MB minimum_object_size 0 KB maximum_object_size_in_memory 16 KB ipcache_size 1024 ipcache_low 90 ipcache_high 95 fqdncache_size 1024 cache_replacement_policy lru memory_replacement_policy lru cache_dir diskd /var/squid/cache0 13000 16 256 cache_access_log /usr/local/squid/var/logs/access.log cache_store_log none emulate_httpd_log off log_ip_on_direct on mime_table /usr/local/squid/etc/mime.conf log_mime_hdrs off debug_options ALL,1 log_fqdn off client_netmask 255.255.255.255 diskd_program /usr/local/squid/libexec/diskd unlinkd_program /usr/local/squid/libexec/unlinkd refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 acl all src 0.0.0.0/0.0.0.0 acl dansubnets src "/usr/local/squid/etc/dansubnets.txt" acl manager proto cache_object acl localhost src 127.0.0.1/32 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 563 acl Safe_ports port 80 #
