Someone who' s clueless. From the World-Wide Web message "404, URL Not Found" meaning that the document you' ve tried to access can' t be located. "Don' t bother asking him...he' s 404, man". 404 is one of the standard response codes of the telnetprotocol on which the Web' s HTTP is based. The first 4 indicates a client error such as a mistyped URL. The middle 0 refers to a general syntax error. The last 4 just indicates the specific error in the group of 40x, which also includes 400: Bad Request, 401: Unauthorized, etc. (2000-03-18)
