Error pages - count as anything?

[Roy Schestowitz <newsgroups@schestowitz.com>]

This may be a redundant or an easy question, but if a user enter a site and
gets a customised 404 page, do packages like Analyae, Webalizer and AWStats
count that as a "visit"? A "hit"? How are such requests for 404.shtml being
treated?

Thanks for your time,

Roy
