Status Code	Value	Description
100	Continue	The client should continue with its request. This provisional response informs the client that part of the request has been received and has not yet been rejected by the server.

201	Created	The request for creating a resource has been fulfilled.
202	Accepted	The request has been accepted, but the processing has not been completed.
203	Non-Authoritative Information	Unauthorized information. The request is successful.
204	NoContent	The server has successfully processed the request, but does not return any content. The status code is returned in response to an HTTP OPTIONS request.

206	Partial Content	The server has successfully processed a part of the GET request.

408	Request Time-out	The server timed out waiting for the request. The client may repeat the request without modifications at any time later.
