Before i start, please forgive my ignorance (I'm still pretty new to this). What I'm using: Ubuntu Server 12.04.3 Webmin 1.660 Squid 3.1 What I'm trying to achieve: I want to have a transparent bridged squid proxy server for caching large, frequently used files. (i.e Apple software updates, iOS .ipsw files). I do not need dynamic content (youtube etc.) to be stored, and general webpage data is not essential (but a definite bonus). The main idea is to increase performance (having to wait only 30sec to download a iOS restore file instead of 15min once the first client has downloaded it). What I have achieved so far: (by myself, by simply “Googling” it) I have managed to setup the server in question with two ethernet cards (one connected to the modem/router, the other to the rest of the network). I have set them up as a bridge (/etc/network/interfaces looks like below) -------------------------------------------------------------------------- # This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto br0 iface br0 inet static address 192.168.2.239 netmask 255.255.255.0 network 192.168.2.0 broadcast 192.168.2.255 gateway 192.168.2.250 bridge-ports eth0 eth1 dns-nameservers (ive removed these just in-case) -------------------------------------------------------------------------- I have also configured iptables to redirect all traffic on port 80 to 3128 This all seems to work fine, but the big problem i have encountered is configuring squid. It seems i can get squid to cache some files and not others. e.g. (part of a sarg log) --------------------------------------------------------------------------------------------------------------------------- ACCESSED SITE CONNECT BYTES %BYTES IN-CACHE-OUT ELAPSED TIME appldnld.apple.com 2 1.40G 87.35% 0.00%/100.00% 00:50:24 ipv4.download.thinkbroadband.com 1 20.97M 1.30% 100.00%/0.00% 00:00:03 --------------------------------------------------------------------------------------------------------------------------- Unless I'm mistaken, I read this as: data requested from 'appldnld.apple.com' 2 times, a total of 1.4GB was downloaded (not quite sure what 87.35% Bytes is), the the important bit, IN-CACHE-OUT, 0%/100% meaning 0% was cached, 100% was purged. However, when I try a test download from www.thinkbroadband.com/download.html it seems to cache the whole file (IN-CACHE-OUT, 100%/0%) Tl;dr So after a long winded explanation of my situation, my question is; How do I configure squid to cache either: 1. All files or 2. Specific files or 3. Files from a specific domain / ip / url Thanks in advance -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Caching-large-files-i-e-ipsw-tp4662838.html Sent from the Squid - Users mailing list archive at Nabble.com.
