I have this squid on ubuntu 12.04 tls. Never version should I install from PPA (like https://launchpad.net/~pdffs/+archive/squid-stable)? Could you give be better source?
I found the cause of the problems. This was the last line:
cache_effective_group proxy
It is also strange. Apparently, with this entry Squid does not have access to something ... But as I read that squid always starts on the powers of root:root, and then divert it to the given, or nobody:nobody. So the group nobody has a better right??
