should use desktop or server version of ubuntu for squid?
does squid really help for decrease traffic direct go thru WAN?
does squid need update always?
i hear someone said, if youtube change script, then proxy server also need to change script to cache youtube, it is true?
In my opinion:
Server version - more stable, less consume of processor power.
Yes, with transparrent proxy (port 80 forwarded transparently to squid port and IP). You can do it also using wpad.dat/wpad.pac file with http server and dns domain - more, more info google.com.
No, not always - you have many things to configure - your choice.
I don’t hear this same, so i have never test it.
use desktop versions only for desktops. it comes with a lot of stuff which is not needed on a host running server tasks. less what can fail from a stability,safety and security perspective.
depends on how much of the traffic is cacheable.
as far as i know youtube did not “allow” to cache the content. so you have somehow to manipulate the http heads for caching and for sure if they change something you may need to change you manipulation rules/scripts as well
