Hi All, This is I used for Squid installation. ./configure --with-pthreads --enable-basic-auth helpers=getpwnam,LDAP --enable-snmp --enable-ssl --enable-linux-netfilter --enable-icap-support --enable-icap-client--enable-external-acl-helpers=ip_user,ldap_group,unix_group --enable-digest-auth-helpers=password --with-openssl=/usr/local/ssl --with-dl make sudo make install. After I insert icap_enable on icap_preview_enable on icap_preview_size 128 icap_send_client_ip on icap_service service_avi respmod_precache 0 icap://localhost:1344/srv_clamav icap_class class_antivirus service_avi icap_access class_antivirus allow all into squid.conf, and them run sudo /usr/local/squid/sbin/squid -NCd1 I got error below: parseConfigFile: 'squid.conf' line 4631 unrecognized: 'icap_enable on' parseConfigFile: 'squid.conf' line 4632 unrecognized: 'icap_preview_enable on' parseConfigFile: 'squid.conf' line 4633 unrecognized: 'icap_preview_size 128' parseConfigFile: 'squid.conf' line 4634 unrecognized: 'icap_send_client_ip on' .................. What's the problem? Thank you in advance.
