Tell me about the HTTP DELETE method

The HTTP DELETE method is used to delete a resource identified by a URI. When sending a DELETE request, the server should delete the specified resource if possible.

Features:

• Idempotency: Repeated DELETE requests to the same resource should have the same effect (either the resource is deleted or it does not exist).
• Responses can vary: 200 OK with a body, 204 No Content without a body, 404 Not Found if the resource is not found.
• Usually does not contain a request body, although the standard does not prohibit it.

Example:

DELETE /api/items/123 HTTP/1.1
Host: example.com

If the resource with ID 123 exists, the server will delete it and return a confirmation. If not, it will return 404.

The DELETE method is often used in REST APIs to manage the lifecycle of resources.
