[squid-users] Squid 2.6 - access hosts outside LAN through proxy with https://a.b.c.d:8080

How would I define the correct ACL and/or http_access rule
to access external hosts, that are to be reached through a https-
admin interface that is using port 8080 ?
I tried to add 8080 to the list of "SSL-Ports" like
acl SSL_ports 443 563 8080
and thus allow it to CONNECT directly with
http_access deny CONNECT !SSL_ports
(rest is kept to the recommended defaults)

 ... but Squid keeps on telling me that the connection is refused (111)

Regards,
