As far as your broken_sites ACL goes, you can’t use `dstdomain`
because the only thing Squid can see of the destination before bumping
an intercepted connection is the IP address. So for `ssl_bump none`
you’ll need to be use `dst` ACLs instead.
ProTip: Here are the Apple and Akamai public IP blocks (to use in a
dst equivalent of your broken_sites), respectively: 17.0.0.0/8,
23.0.0.0/12.
Good luck

So adding:
acl broken_sites dst 23.0.0.0/12
now gives me the below:
Jun 30 20:16:51 gateway (squid-1): 192.168.1.100 - -
[30/Jun/2014:20:16:51 -0600] "CONNECT 23.204.162.217:443 HTTP/1.1"
403
3385 TCP_DENIED:HIER_NONE
Jun 30 20:16:51 gateway (squid-1): 192.168.1.100 - -
[30/Jun/2014:20:16:51 -0600] "NONE error:invalid-request HTTP/0.0"
400
3981 TAG_NONE:HIER_NONE
So something is off. Any help on these beastie? Thank you.
