202 Status Code Explained
The status code 202 indicates that server has received and understood the request and that it has been accepted for processing, although it may not be processed immediately.
Why it Occurs
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 for re-sending a status code from an asynchronous operation such as this.The 202 response is intentionally non-committal. Its purpose is to allow the server to accept a request for some other process without requiring that the user agent's connection to the server persist until the process is completed.
What it means
The entity returned with this response SHOULD include an indication of the request's current status and either a pointer to a status monitor or some estimate of when the user can expect the request to be fulfilled.
