manually typing a url is a direct request.
clicking a link is a referred request.
there's no way to track a direct request.
in some cases where the Referer: header is not sent with the request, you could have a visitor who clicked a link and that referred request is not trackable so it would look like a direct request in analytics and your server access log file.
