So is this a correct summary:
Log shows size 0 iff client dropped the connection before the
interaction was complete (HTTP result code 000 vs. something else is
just a question of when the drop was detected);
In other words, 0 size in the log can _never_ mean all is well, server
result was empty, because if all is well at least some header info
will have been sent.
