This description from Squid FAQ
Cache/Log (Squid 1.x) or Swap.State (Squid 2.x)
This file has a rather unfortunate name. It also is often called the swap log. [...]
It’s simple, use this command :
# squid -k rotate
This command rotate squid log files but also ‘clear squid cache’, without shutdown and restart squid. This command works in the situation where people have ‘a constant cache’ (refresh/reload a page doesn’t work) in their browser, and ‘clear cache’ without their notice.
What about squid -z?

OPTIONS FOR EXTERNAL SUPPORT PROGRAMS
dns_nameservers 208.67.220.220 208.67.222.222
or
dns_nameservers 208.67.220.220
dns_nameservers 208.67.222.222
Save and run this :
squid -k parse
squid -k reconfigure
but if your squid add nameservers from squid.conf, [...]
Add this to squid.conf

If reboot and squid -k says it can not send stop signal again, means that squid.pid is missing
Check squid.pid in the system and if missing, here is what i can suggest :

squid -k shutdown
Create squid.pid (usually squid.pid located in the same directory with log files)
touch [...]
The squid.pid file is missing or unreadable makes squid -k command don’t work (says it can not send stop signal). We kill Squid manually by finding the process ID with ps.
ps ax | grep squid
If there are more than one Squid process, be sure to kill the one that shows up as (squid).
example
500 [...]
