Re: Fwd: [squid-users] URL redirection in offline mode

May be I do something wrong - but my ACL doesn't help.

------------ part of "squid.conf" -------------------

http_access allow manager localhost
http_access deny manager
# nach Buch

http_access deny CONNECT !SSL_ports
http_access deny Dangerous_ports

# nur LAN erlaubt (ist das doppelt gemoppelt?)
http_access deny !localnet

include /etc/squid/conf.d/schlafen.conf

# ....

-------------- end squid.conf -----------------------------

with

------------- /etc/squid/conf.d/schlafen.conf --------------

acl Schlafzeit time 00:00-05:59
http_access allow !Schlafzeit
#

-------------- end schlafen.conf ----------------------------

Early in the morning I get the following messages in "/var/log/
