      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.
