2 questions about proxy hierarchy

["Eugene M. Zheganin" <emz@xxxxxxxxxxxxx>]

Hi.

Happy world ipv6 launch day to everybody. :P

squid/3.1.12, FreeBSD 8.x|9.x

a) why when using ipv6 address, like fd00::316 or, no matter 
[fd00::316], squid detects that configuration file is corrent, but then 
I'm immidiately getting "TCP connection to fd00::316/3128 failed", but, 
in the same time, I CAN telnet to the fd00::316 port 3128 ?

b) more long story. I think I'm just not getting something. From the 2.6 
version I always had to use no-query option for parents. That is because 
the cold squid is always detecting the parent proxy as dead, but the 
weird thing is, it's still capable of communicating to them. I mean I 
see udp/3130 packets in tcpdump going both ways, and UDP_HIT/000 
UDP_MISS/000 ICP queries from children on parent proxies.
Why is that ?

Thanks.
Eugene.
