It really depends on the environment and links speed you do have now. If you do a very specific thing which is use a cache_peer only for windows updates while using a hierarchy like this: Main LB and router proxy -> domain specific proxy cache_peer on the domain specific cache_peer instance or machine use: #start range_offset_limit -1 maximum_object_size 2 GB # or any other size that you think worth and make sense. quick_abort_min -1 #end I am not following windows updates too much but I assume that these updates has a pattern by the url and or headers which can clarify how it *should* be cached safely. this wiki: http://wiki.squid-cache.org/SquidFaq/WindowsUpdate is not up to date with all the settings but it's a good started in the research of "windows update in the internet". If you have a local windows network and server you can just add WSUS service that will build a updates store which is better for many networks.
