After shutdown squid, navigation still works

[Anderson dos Santos Donda <andersondonda@xxxxxxxxx>]

My squid works fine, all acls works too..

but when I shutdown the squid ( sbin/squid -k shutdown )

The navigation still working on clients, and the all acls rules does
not work.. I need reboot the server to all back works fine..

someone have a idea?

PS: In my squid logs have many log like: WARNING: transparent proxying
not supported


My squid is: Squid 3.0 Stable 18


Thanks for all...
