I forget exactly why it was there. Likely a crash when it was
non-NULL when it should have been NULL. Fixed now anyway.
Current CVS (checkout two minutes ago at 11.35pm GMT) is pretty much
broken again regarding the internal DNS. Pages don't open when you hit
a CNAME and I get frequent errors like
2008/01/12 00:33:12| ipcacheParse: No Address records in response to
'www.hp.com'
2008/01/12 00:33:37| ipcacheParse: No Address records in response to
'welcome.hp-ww.com'
2008/01/12 00:36:15| ipcacheParse: No Address records in response to
'www.google-analytics.com'
in the cache.log. It looks like DNS times out a couple of times.
Debugging section 14 does not give more results. The query
00:41:59.075658 IP 83.170.1.240.36282 > 83.170.1.240.53: 37174+ AAAA?
www.hp.com. (28)
00:41:59.075913 IP 83.170.1.240.53 > 83.170.1.240.36282: 37174 1/1/0
CNAME www.hpgtm.nsatc.net. (116)
is repeated several times. This only seems to happen when you hit a
CNAME on an IPv4-only host, CNAME to dual-stacked or IPv4-only with an
address directly associated to the hostname works.
Sigh, thats so weird.
Sorry the proper debug options to trace this are:
debug_options ALL,0 14,9 78,9
It's working perfectly here. On those same domains too.
Found out it breaks when you set
dns_v4_fallback no
in the config. If you do, the debugging output is

If you don't do it it works, but at least back when you added it it was
desperately needed.
