Hello, I'm working with some scripts to prefetch content but having some trouble, what I can't work out is a way to check if a given object is already cached, in other words, I want to check if the object I'm going to download is going to hit, in which case I can ignore it. I've read squidcli

[squid-users] Squid doesn't do a fallback from ipv6 to ipv4, if the ipv6 connect fails
