I have this scenario:
a frontend squid 3.2.0.7 with workers intercepting traffic with tproxy,
and caching in memory small files.
a backend squid 3.2.0.7 parent, serving files from disk.
the two squid comunicate via htcp, and that work pretty well (although I
see very often on the frontend one or few processes with high cpu usage,
while the rest remain low, I don't know if this is a normal behaviour).
Now I'm trying to use squid 3.2.0.13 or above to get advantage of the
shared memory feat, but I cannot get it working with its parent. If I
use the proxy manual on my browser(the frontend proxy), it works, but
with tproxy, it never fetch the content from its parent.
Thank you.
