Just to clarify, HTTP metadata can be thought of as a set of properties with (mostly) well-defined targets. For example, Expires is not saying anything about the resource identified by that URI. It is representation metadata, an entity-header, that defines a property of the particular representation included in the message (or by inference in the case of 304). ....Roy
