Hi All. I've been doing lots of reading and I believe I am understanding the basic concept of how to use Squid. /I've posted the hardware that I am using at the bottom of the post/. I have about 12 windows machines running at any one time and I was hoping to start using Squid to speed up the Windows updates in this environment - *NOTHING ELSE FOR NOW*, as I don't want the cache to potentially interfere with the other work going on. I will consider adding complexity as I go and continue to learn how to use it. For Practise I installed Squid using apt-get on a Linux Mint15 installation - install went smoothly. I found the the *How do I make Windows Updates cache?* wiki here: http://wiki.squid-cache.org/SquidFaq/WindowsUpdate <http://wiki.squid-cache.org/SquidFaq/WindowsUpdate> It looks straight forward - just copy and past the appropriate settings from that page into the squid.conf file. What I am not clear on is how to NOT CACHE anything else? Would someone be able to help me with that? Thanks. p.s. I was considering these tweaks to the squid.conf file cache_dir ufs /etc/squid3/cache01 450000 16 256 cache_mem 750 MB Mint15 only uses about 380 MB of Ram once up an running.
