Sometimes I try to figure out why I get so many entries in my error logs for the home page where someone requesting it should be seeing "index.html". Most of the referrers are from other pages on my web site, so maybe there's some strange link problem...?

Anyway, another mystery (or is it the same mystery?) is the number of entries in my error log looking for a nonexistent "none" file in those directories. Here's a clip from today's error log where an IP address in Mexico requested the file maybe 50 or 60 times, quickly:

This shows just a few of the recent entries.

I created an empty file called "none" in the home directory so now they won't get anything, but I don't know why they were requesting it in the first place.

Can someone point me to a place where I can RTFM on this issue?
