     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.
