Hello
After spending hours configuring squid 3.2.5, I only get TCP_MISS. To
narrow the problem, I will focus on one PNG file that I want cached, but
note that I get TCP_MISS for 99% of my requests, not only PNG files.
Refreshing doesn’t help, it never gets a TCP_HIT.

in cache.log, I get:

Note that I doubled check that my cache directories belonged to
squid:squid and their size slowly grows when I am using squid, yet I get
a TON of tcp_miss, even on cacheable sites (such aswww.lci.fr)
Any idea?
