Error 404--Not Found

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.

IBM is stepping up its virtualization offerings with technology focused on moving applications among systems.

Last week, the company announced that it was buying Meiosys. Meiosys has an interesting technology. It can relocate running applications because its MetaCluster software virtualizes systems at the application level, separating applications, connections and processes from hardware. IBM is one of several systems vendors, including HP and Sun, who already have a relationship with Meiosys. IBM says it will integrate the MetaCluster technology into new products that should be available by the end of the year. Get more detail here.
