202 Accepted

The 202 (Accepted) status code indicates that the request has been
accepted for processing, but the processing has not been completed.
The request might or might not eventually be acted upon, as it might
be disallowed when processing actually takes place. There is no
facility in HTTP for re-sending a status code from an asynchronous

The 202 response is intentionally noncommittal. Its purpose is to
allow a server to accept a request for some other process (perhaps a
batch-oriented process that is only run once per day) without
requiring that the user agent’s connection to the server persist
until the process is completed. The representation sent with this
response ought to describe the request’s current status and point to
(or embed) a status monitor that can provide the user with an
estimate of when the request will be fulfilled.
