Idempotency

Choose the best answer for: safe retries
Options
  1. 1No dedup, since the server can't tell a retry from a brand-new request
  2. 2Always retry, because re-sending a request is safe for every HTTP verb
  3. 3Only for GET, since non-idempotent methods can never be safely retried
  4. 4Idempotency keys ensure same operation isn't processed twice
