I got a new result by doing test. Perhaps the question is "Why do I need squid -k shutdown?" Sometimes, Squid cannot run after system booting (put Squid in rc.local). No webcache running checked by netstat -a, but system claims that Squid is exist when I try to load Squid (running but not serving). After shutting down Squid and load manually, it can run well. The problem (could not shutdown Squid) is a trouble. The result, in both tests (patched and un-patched) Squid can be shutted down nicely when the webcache service exist in netstat -a. I think the problem of cannot shutdown Squid is only happen in case the problem happen (running but not serving). However, Squid 2.5S10 (without patches) can be shutted down in any condition.
