And bingo!  This appears to have taken care of the display, although I
still need a few more tests...  Thanks to both the posters who pointed
me to the path of true enlightenment...

Well, 'mainserver' isn't exactly correct...  the port redirect sends
those named requests off to a Java listener.  The actual server name is
something else entirely.  This is all so that if the hardware fails, we
can get back up and running quickly by moving the CNAME records to
another system, where the httpd.conf file is prepared and waiting,
without having to issue or move IP addresses.
