I disagree: 204 (<http://greenbytes.de/tech/webdav/rfc2616.html#status.204>): "The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation. The response MAY include new or updated metainformation in the form of entity-headers, which if present SHOULD be associated with the requested variant. If the client is a user agent, it SHOULD NOT change its document view from that which caused the request to be sent. This response is primarily intended to allow input for actions to take place without causing a change to the user agent's active document view, although any new or updated metainformation SHOULD be applied to the document currently in the user agent's active view. The 204 response MUST NOT include a message-body, and thus is always terminated by the first empty line after the header fields." Note the second paragraph. 404 (<http://greenbytes.de/tech/webdav/rfc2616.html#status.404>): "The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent. 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. This status code is commonly used when the server does not wish to reveal exactly why the request has been refused, or when no other response is applicable." This seems to be exactly right (unless 410 is more precise). Julian -- <green/>bytes GmbH -- http://www.greenbytes.de -- tel:+492512807760
