HTTP 205 Reset Content vs 428 Precondition Required
HTTP 205 (Reset Content) is a 2xx Success response, while 428 (Precondition Required) is a 4xx Client Error response. 205 indicates that the server fulfilled the request and the client should reset the document view (e.g., clear a form). In contrast, 428 means that the server requires the request to be conditional (e.g., include If-Match header) to prevent lost updates.
