Squid-3.1.12 and later releases have the fix.

OK, I've built and installed Squid 3.1.12, run squid3 -k parse, and removed the
'acl all src all' and 'upgrade_http0.9 deny shoutcast' entries, as
these were causing errors. Conf is now:

However, when I look at access.log now, I'm seeing the following:
TCP_MISS/200 5223 CONNECT [domain.com]:443 - DIRECT/xxx.xxx.xxx.xx -

Whereas with Squid 2 I was seeing:
TCP_MISS/000 307 CONNECT [domain.com]:443 - FIRST_UP_PARENT/AB -

Is there a difference in the way Squid 3 matches the 'site' dstdomain
entry and calls the AB cache_peer address?

Is xxx.xxx.xxx.xx the IPs of the peer? or some other place in public DNS?

FYI: We fixed the handshake bug by opening a socket to the peer then if the peer was an origin with the right port number, passing the socket to the DIRECT packet handling code for the SSL handshake. It's possible that code set "DIRECT" flag on the request for logging. Or that peer selection is still blocking the origin peer somehow despite the port match.

(The 200 status change is a separate bug fix)
