Hi, I've some squid servers (until 3.1.20 version) which has the following configuration and works great: acl allowed_protocols proto HTTP HTTPS CONNECT FTP http_access deny !allowed_protocols After the upgrade to 3.3.3 version, sqiud print the following warning in the configuration check: WARNING: Ignoring unknown protocol 'CONNECT' in the ACL named 'allowed_protocols' and squid clients can't no more connect to HTTPS sites. How can I check the protocols like configuration in old versions?-- -- Davide Belloni
