[squid-users] caching apt package lists/Raspbian

[TarotApprentice]

Recently upgraded to Raspbian Buster and squid 4.6. Since then I am unable to cache the Packages.xz that apt uses. The various other Pis using this proxy all end up downloading the 30MB Packages.xz every time. Does anyone have any suggestions on how to get it to cache?

Cheers
MarkJ
