Here's what I do
----------------

In squid.conf:
logfile_rotate 0

From cron I run the following script:
-------------------------------------------------------------
#!/bin/sh
#
# $Id: squid.rotate,v 1.5 1999/10/14 01:59:46 root Exp $

prog=`basename $0`

ARCHDIR=/var/log/archive/squid
LOGDIR=/var/log/squid
LOGS="access.log cache.log store.log"

cd $LOGDIR

# timestamp the logs
now=`date "+%Y%m%d.%H%M%S"`
if [ -z "$now" ]; then
# highly unlikely but paranoia never hurt anyone
echo "$prog: cannot get date - exiting"
exit 1
fi

for log in $LOGS; do
if [ -f $log ]; then
mv $log $log.$now
fi
done

# get squid to rotate the logs
/squid/bin/squid -k rotate

# if everything worked, move the logfiles to the archive dir
sleep 30 # let squid catch up
for log in $LOGS; do
if [ -f $log ]; then # the proper log exists
mv $log.$now $ARCHDIR
fi
done

# make 'em smaller
cd $ARCHDIR
for log in $LOGS; do
if [ -f $log.$now ]; then # the proper log exists
gzip $log.$now
fi
done

exit 0
-------------------------------------------------------------

By putting the date AND time on the logs, it allows multiple rotations in
one day.

No need to hack squid for that one. Assuming that you have set
"logfile_rotate 0" in squid.conf, this little script should do the
trick:

#! /bin/sh
LOGDIR=/var/squid/logs
LOGFILES="access.log cache.log"
datestr=`date '+%Y%m%d'`

for f in $LOGFILES
do
mv $LOGDIR/$f $LOGDIR/$f-$datestr
done
squid -k rotate
for f in $LOGFILES
do
gzip $LOGDIR/$f-$datestr
done

Hello

There is nice utility called newsyslog. You just need
to patch it to copy/truncate the log instead of moving it
and squid is happy.

If you are using Windows, then probably not.

Under Unix, this is standard procedure.

There already exists several tools for maintaining log files. One good
example of a log rotating framework with all functionality you will ever
need is logrotate from RedHat.
