   A REST API returns paginated results using HTTP Link headers. The `Link` header contains `<https://api.example.com/items?page=2>; rel="next"`. A developer must retrieve all items. What is the correct way to use this header?

   • AUse the header only for the first request, then stop after the second page.
   • BStore the entire header as a string and send it as a query parameter.
   • CParse the header, extract the URL with `rel="next"`, and request that URL in the next iteration.
   • DIgnore the header and manually increment the `page` parameter until an empty response is received.

   • BKeep `offset` at 0 and increase `limit` by 50 each iteration.
   • CSet `offset` to the value of `total` after the first request.
   • DIncrement `offset` by 50 in each loop iteration until `offset >= total`.
