I want to setup a caching proxy that will cache large files, but by default squid seems to not cache anything. I'm really new to proxy administration so not sure what I have to do to make it cache even large files. This proxy will be used by the AV updates so when 900 machines update at once, the definitions will be cached in the proxy rather then each machine going online. So I want files even as big as 5MB to be cached. I'd probably set a few machines to update before all the others, to ensure there's a full cached copy on the proxy.
