Content-Location header indicates an alternate location for the returned data. The principal use is to indicate the URL of a resource transmitted as the result of content negotiation.
Content-Location are different.
Location indicates the URL of a redirect, while
Content-Location indicates the direct URL to use to access the resource, without further content negotiation in the future.
Location is a header associated with the response, while
Content-Location is associated with the data returned. This distinction may seem abstract without examples.
