Based on squid documentation:
[url]http://wiki.squid-cache.org/SquidFaq/OperatingSquid#I_want_to_restart_Squid_with_a_clean_cache[/url]

To clear / reset squid cache on FreeBSD (sometimes cache directory can grow very big), first shutdown squid:
[code]# /usr/local/etc/rc.d/squid stop
Stopping squid.
Waiting for PIDS: 1650.[/code]

Move old cache directory and create new one. Make sure same permissions are set on new one:
[code]
# cd /var/squid/
# ls -la
total 32
drwxrwxr-x 8 squid squid 512 Mar 3 11:30 .
drwxr-xr-x 7 root wheel 1024 Mar 3 10:31 ..
drwxr-xr-x 2 squid squid 512 Apr 25 2013 ca_path
drwxr-x--- 67 squid squid 1024 Apr 26 2013 cache
drwxr-xr-x 3 squid squid 512 May 1 2013 lib
drwxr-x--- 2 squid squid 512 Sep 4 2012 logs
drwxr-xr-x 2 squid squid 512 Mar 3 11:31 swap
# mv cache cache.old
# mkdir cache
# chown squid:squid cache
# chmod 750 cache
# ls -la
total 32
drwxrwxr-x 8 squid squid 512 Mar 3 11:30 .
drwxr-xr-x 7 root wheel 1024 Mar 3 10:31 ..
drwxr-xr-x 2 squid squid 512 Apr 25 2013 ca_path
drwxr-x--- 2 squid squid 512 Mar 3 11:30 cache
drwxr-x--- 67 squid squid 1024 Apr 26 2013 cache.old
drwxr-xr-x 3 squid squid 512 May 1 2013 lib
drwxr-x--- 2 squid squid 512 Sep 4 2012 logs
drwxr-xr-x 2 squid squid 512 Mar 3 11:31 swap
[/code]

Next, initialize the new cache directory:
[code]
# squid -z
