Basic Varnish configuration for /etc/default/varnish

varnish

# Oh, wow. So those other configuration files
# looked pretty readable. This one, though, 
# looks OOOOOLLLD. It is old. And so it's 
# less readable. But let's talk about it.

# Run on startup? Yes.
START=yes

# Set the number of files this daemon can
# touch. We need los of them because each
# open socket for a network connection needs
# a single file open.
NFILES=131072

# Memlock is http://linux.die.net/man/5/limits.conf,
# the maximum memory this process can use,
# in KB.
MEMLOCK=82000

# What things do we want to pass to the daemon?
# -a :8000 means listen on address (port) 8000.
# -T localhost:82 means allow the Varnish admin
# to run locally on port 82.
# -f points to our Varnish config file.
# -S Is where we hide Varnish secrets.
# -s is how much cache we want -- 16mb should
# be just fine.
