[squid-users] CONNECT acl protocol

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?--
