404 is not an error on the part of the server but a perfectly well defined
and normal response. If I ask you for a glass of wine and you tell me
there's no wine, that doesn't indiate an error on your part. An error would
be if you tell me "green" in response to the question "what colour is
wine?". One cannot even say it's an error on part of the client - it depends
on context. If the client is, say, purposefully sending a bunch of random or
semi random requests (maybe DOS attack), then it's not in error when
requesting nonexistant pages. Programmers call responses like 404 errors out
of sloppiness or laziness.
