@Header("Content-Location") public class ContentLocation extends BasicUriHeader
Represents a parsed Content-Location HTTP response header.

An alternate location for the returned data.

Example

Content-Location: /index.htm

RFC2616 Specification
The Content-Location entity-header field MAY be used to supply the resource location for the entity enclosed in the message when that entity is accessible from a location separate from the requested resource's URI. A server SHOULD provide a Content-Location for the variant corresponding to the response entity; especially in the case where a resource has multiple entities associated with it, and those entities actually have separate locations by which they might be individually accessed, the server SHOULD provide a Content-Location for the particular variant which is returned.

Content-Location = "Content-Location" ":" ( absoluteURI | relativeURI )

The value of Content-Location also defines the base URI for the entity.

The Content-Location value is not a replacement for the original requested URI; it is only a statement of the location of the resource corresponding to this particular entity at the time of the request. Future requests MAY specify the Content-Location URI as the request- URI if the desire is to identify the source of that particular entity.

A cache cannot assume that an entity with a Content-Location different from the URI used to retrieve it can be used to respond to later requests on that Content-Location URI. However, the Content- Location can be used to differentiate between multiple entities retrieved from a single requested resource, as described in section 13.6.

If the Content-Location is a relative URI, the relative URI is interpreted relative to the Request-URI.

The meaning of the Content-Location header in PUT or POST requests is undefined; servers are free to ignore it in those cases.
