pub const CONTENT_LOCATION: HeaderName;
Indicates an alternate location for the returned data.
The principal use case is to indicate the URL of the resource transmitted as the result of content negotiation.
Location and Content-Location are different: Location indicates the target of a redirection (or the URL of a newly created document), while Content-Location indicates the direct URL to use to access the resource, without the need of further content negotiation. Location is a header associated with the response, while Content-Location is associated with the entity returned.
