Hi, I have a number of SquidNT 2.6 Stable 17 caches running on Windows XP machines. I am being told that users are having problems uploading files to webmail apps and other sites (moodle) that allow for uploading. I am not sure what I should be looking at, is there anything that I should be looking at? I have supplied my config file, removing any company specific information. Thanks. If they bypass the local squidnt proxy, they can successfully upload. http_port 8080 cache_peer proxy.############### parent 8080 3130 no-query default login=PASS hierarchy_stoplist cgi-bin ? acl QUERY urlpath_regex cgi-bin \? no_cache deny QUERY cache_mem 32 MB maximum_object_size 30720 KB cache_dir aufs c:/squid/var/cache 60000 16 256 auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hours auth_param basic casesensitive off 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 manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 563 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 563 # https, snews 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 acl snmppublic snmp_community ############### acl snmpprivate snmp_community ############### acl Purge method PURGE http_access allow localhost Purge http_access deny Purge http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports acl block url_regex -i "c:/squid/var/logs/block.conf" acl unblock url_regex -i "c:/squid/var/logs/unblock.conf" acl nocache url_regex -i "c:/squid/var/logs/nocache.conf" no_cache deny nocache http_access deny block !unblock http_access allow all http_access deny all http_reply_access allow all icp_access allow all cache_mgr webmaster visible_hostname SquidNT.proxy.local always_direct deny all never_direct allow all snmp_port 3401 snmp_access allow snmppublic snmp_access allow snmpprivate snmp_access deny all snmp_incoming_address 0.0.0.0 snmp_outgoing_address 255.255.255.255 coredump_dir c:/squid/var/cache access_log c:/squid/var/logs/access.log squid cache_log c:/squid/var/logs/cache.log
