Nov 7 15:33:25 sit-gate squid[16605]: Starting Squid Cache version
3.2.3 for x86_64-unknown-linux-gnu...

what's wrong with this:
#acl manager proto cache_object
#acl localhost src 127.0.0.1/32 ::1
acl localhost src 127.0.0.1/32
#acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1
acl to_localhost dst 127.0.0.0/8 0.0.0.0/32

thanks for help.
Cheers
