Just a wee note to remind myself of the best way to view your squid.conf file if you’re in a hurry:

'cat squid.conf | grep -v ^# | grep -v ^$'

Its interesting to note that many people recommend stripping the comments from the active squid.conf with a command similar to this:

'cat /etc/squid/squid.conf | tee /etc/squid/squid.conf.commented \
 | grep -v ^# | grep -v ^$ > /etc/squid/squid.conf.nocomment'

Naturally you would normally not have ‘.nocomment’ on the active file.  You need to be root to do this too.
