All connections should be logged as requests that came from clients
along with details on how the server responds. Some indication that
the connection was aborted should be made in the log, perhaps with a
count of how many bytes were transferred. In cases where no response
is going to be sent and the connection aborted, the response code
shown in the log could be left blank or as a placeholder (e.g. "xxx").
The general principle is that we always want visibility into what
happens with every connection -- in many situations we are serving
anonymous clients who aren't going to call and complain or post a
trouble ticket, so it's nice to see such aborted conns in the logs as
an indication that we might need to investigate what's going on.

Hello,
There are certain cases where connections probably ought to generate
access log entries but do not. Specifically if an ADP exits via
ns_adp_abort no access log entry will be generated, but data may have
been returned to the client. This seems like a bug.
I wonder - should this be the documented known behavior of
ns_adp_abort vs. ns_adp_return? i.e., abort indicates that the
connection is intentionally terminated, not logged, etc. vs.
ns_adp_return which halts ADP processing but continues the
connection, which includes logging, etc.
I'm inclined to agree with you that the current behavior is a bug,
but it raises the question: should there be such a function that
says "this connection wasn't handled, don't even log it" - or,
should ALL connections always be logged, even if it's aborted?
Thanks, Andrew.
