206	Partial Content	The server is delivering only part of the resource due to a range header sent by the client.

400	Bad Request	The server cannot or will not process the request due to an apparent client error.

422	Unprocessable Content	The request was well-formed but was unable to be followed due to semantic errors.
423	Locked	The resource that is being accessed is locked.
424	Failed Dependency	The request failed because it depended on another request and that request failed.
