From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

Daniel Burrus
Founder and CEO, Burrus Research Associates
More than 1,800 audiences have listened to Burrus talk about new technologies, detail creative applications and posit future effects. That's quite a wide reach for the technology forecaster, consultant and author of Technotrends. Among the predictions Burrus takes credit for is a 1984 call that the sequencing of the human gene code would occur by the end of the century. Officially, it happened about six months into the new millennium, but he was pretty darn close.
Geoffrey Moore
Chairman and founder, The Chasm Group
What might Hewlett-Packard, IBM, Microsoft, Oracle and Sun possibly agree on? Moore's ability, apparently. All were once clients of Moore, a former English professor who has taught high-tech marketing to a generation of computer makers over the past decade through his consulting and writing. He's known as the Chasm Guy in some Silicon Valley circles, a reference to Moore's signature metaphor and the title of his acclaimed book, Crossing the Chasm, which is about bridging the gap between two kinds of customers, the visionary and the pragmatist. His fourth book, Living on the Fault Line: Managing for Shareholder Value in the Age of the Internet, came out in August. It's aimed at old-economy executives faced with adjusting to the Internet Age.
