Henrik, Please find my below observations while downloading this ISO DVD (via Proxy & Bypassing the proxy) via Proxy Server: 1) I am able to download the ISO file using Firefox Browser 2) I am NOT able to download the file using Internet Explorer (IE 6.0) Bypassing Proxy Server & directly connected to internet: 1) I am able to download the ISO file using Firefox Browser 2) I am able to download the file using Internet Explorer (IE 6.0) There was no error being reported on the client end whenever I download the file using IE through proxy server... Once the download link is clicked it just pop's up for open/save then it ends in downloading just 1KB of the file. I use manual proxy settings on port no. 74 SQUID.CONF: http_port 74 acl QUERY urlpath_regex cgi-bin \? cache deny QUERY cache_mem 64 MB cache_swap_low 90 cache_swap_high 95 maximum_object_size 4096 KB # minimum_object_size 0 KB # maximum_object_size_in_memory 8 KB ipcache_size 1024 ipcache_low 90 ipcache_high 95 # fqdncache_size 1024 cache_replacement_policy lru memory_replacement_policy lru cache_dir ufs /usr/local/squid/var/cache 8192 16 256 logformat squid %ts.%03tu %6tr %>a %Ss/%03Hs %<st %rm %ru %un %Sh/%<A %mt logformat squidmime %ts.%03tu %6tr %>a %Ss/%03Hs %<st %rm %ru %un %Sh/%<A %mt [%>h] [%<h] logformat common %>a %ui %un [%tl] "%rm %ru HTTP/%rv" %Hs %<st %Ss:%Sh logformat combined %>a %ui %un [%tl] "%rm %ru HTTP/%rv" %Hs %<st "%{Referer}>h" "%{User-Agent}>h" %Ss:%Sh # access_log /usr/local/squid/var/logs/access.log squid cache_log /usr/local/squid/var/logs/cache.log cache_store_log /usr/local/squid/var/logs/store.log emulate_httpd_log off log_ip_on_direct on mime_table /usr/local/squid/etc/mime.conf 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 # request_header_max_size 20 KB # request_body_max_size 0 KB #Suggested default: 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 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 http_access allow all http_access allow manager localhost http_access deny manager # Deny requests to unknown ports http_access deny !Safe_ports # Deny CONNECT to other than SSL ports http_access deny CONNECT !SSL_ports http_access deny all http_reply_access allow all icp_access allow all reply_body_max_size 0 allow all cache_mgr webmaster cache_effective_user squid visible_hostname testproxy@xxxxxxxxxxxxxx coredump_dir /usr/local/squid/var/cache Kindly let me know why my Internet Explorer is not using to download the file using Squid Proxy.
