Hi,
i configure squid to use cache. It seems to work because when i did a
try with a software's download, the second download is TCP_HIT in the
access.log.
The question i have is : why the majority of requests can't be cached
(i have a lot of tcp_miss/200) ? i found that dynamic content is not
cached but i don't understand.very well.
That's the way internet works ... most of the traffic is
dinamically generated, which in default squid configurations avoid the
content to be cached. Nowadays, with the 'everything https' taking
place, HTTPS is also non-cacheable (in default configurations).
And by default configurations, you must understand that they are
the 'SECURE' configuration. Tweaking with refresh_pattern is usually not
recommended except in some specific cases in which you're completly
clear that you're violating the HTTP protocol and can have problems with
that.
In short, the days of 20-30% byte-hits are gone and will never came
back anymore.
Keep your default (and secure) squid configuration, there's no need
to tweak refresh_pattern unless on very specific situations that you
clearly understand what you're doing.
