Link Header

Link headers are a way to signal available actions to clients. Which actions can be available and how you can perform these actions are documented in the Media-Type specification corresponding to the Content-Type you got back from the server.
Links are identified using their `rel` parameter and always have a `href`.
Common Links
- `rel=self`: This is the canonical URL for this resource. PUT and DELETE requests should generally be done here.
- `rel=next`: The next page in a list
- `rel=prev`: The previous page in a list
- `rel=first`: The first page in a list
- `rel=last`: The last page in a list
A full list of publicly registered relation types can be found on the IANA Link Relations page.
Additional Properties
A link can have other optional properties as well, an example is the `templated=true` property that should be added if a client is supposed to fill in a URL Template.
