Is the DELETE method idempotent or not? Why?

The DELETE method in HTTP is considered idempotent. This means that executing the same DELETE request multiple times will result in the same outcome — the resource being deleted.

Why:

• The first request deletes the resource.
• Subsequent requests will not find the resource, but the system's state will not change (the resource is already deleted).

Thus, regardless of the number of repeated DELETE requests, the server's state after them will be the same, which is the essence of idempotency.
