RE: [squid-users] Images are not loading properly into web pages. (not sure about my cache settings)

Your mail explained a lot. (thanks)
 
Query:
 
I infer that squid should be run with "nobody" user with least priviliges and providing read/write access to logs and squid data dirs is good enough. There is no need to run " Sudo Squid3". As these priviliges are already assigned to the software by the linux distro the Squid package comes with.This is the portion which i am confused about as there are many texts available on the net which suggest that is should be chrooted(which honeslty look complex to me as well) while others explaining that giving directory permissions is good enough. I want to know the best and safe practice no matters even if it requires a little more hassle.
 
 
 
Secondly the default packaged software Version 3.0.STABLE1 that comes with Ubuntu is good enough and there is no reason to moe to stable24 unless you have a specific need. However upgrading the software will preserve the configuration settings of version 3.0 stable1 and will be installed in the same path.
 
Please guide further

regards,
