Re: AW: [squid-users] SQUID 3.3.8 doesn't cache files greater than 50KB

Hey there,

There is a way to force a fetch of a full object when a partial byte
range accrues.
You can take a look at the example here:
http://wiki.squid-cache.org/SquidFaq/WindowsUpdate#How_do_I_make_Windows_Updates_cache.3F

Which is intended for windows update but also applies for other downloads.
My recommendation is to use the options wisely to not consume too much
of the bandwidth without any real reason.
