I'm sorry about that Doug ... I flaked on you there.
The problem is that the Apache/mod_webkit side cannot even
get the socket connected. I forgot that, and that I had to
add debug output* to mod_webkit.c (mod_webkit2) to uncover
my initial hunch. Hey, that was January.

Well, I lost that one. Shouldn't have jumped the gun.
When you returned to the  "localhost 8086" configuration
(with Apache set to "LogLevel debug" in main or vhost config)
I expected you to see the "Couldn't connect to AppServer"
failures in your Apache error log.

So I guess you (Mac OS X 10.3.2, Apache/1.3.29, mod_webkit
[not mod_webkit2]) don't have this bug. And Todd Grimason's
keen eye caught your bug.

Best,

* For the interested:
  The problem boils to a behavior in getipnodebyname(3).
  If IPv6 is defined for your host, the IPv6 addr for localhost
  [::1] is the first in the list ultimately returned through
  getaddrinfo(3) and back to Apache's apr_sockaddr_info_get().
  So at startup Apache and mod_webkit2 set up the address
  structures for a perfectly fine IPv6 connection. But when
  the request comes through for the web page, mod_webkit2's
  wksock_open() gets refused (error=97) on socket creation
  because it tries to use that IPv6 info to open an
  IPv4 connection.

  One passable solution might be to change wksock_open() to
  read the address family from the returned-and-stored address
  structure instead of the hardcoded AF_INET. My workaround
  used the ability to request priority for IPv4 addresses in
  the response from (ultimately) getipnodebyname(). Specifying
  an actual address in the Apache conf can work too, provided
  it isn't actually an IPv6 address.

I changed httpd.conf back to read localhost, restarted Apache, and
restarted AppServer. Everything still works as before so it must have
been something else.

In any case, I'm not sure how to check which protocol a port is opened
with.
