Understanding HTTP Idempotency HTTP idempotency guarantees that making multiple identical requests produces the same result as a single request. This becomes critical when network failures cause clients to retry opertaions, ensuring that duplicate requests don't alter server state unexpectedly. The HTTP specification classifies methods by their ...
