SSC Error List (SL Multi-Channel Receiver DW)
12.2.3 202 Accepted
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 operati-
on such as this.
12.2.4 210 Partial Success
The request has been partially accepted for processing.
12.3 3xx Redirection
This class of status code indicates that further action needs to be taken by the user agent in order
to fulfill the request. The action required MAY be carried out by the user agent without interaction
with the user.
A client SHOULD detect infinite redirection loops, since such loops generate network traffic for
each redirection.
12.3.1 310 Subscription Terminates
The subscription is terminated on the SSC Server, because the lifetime expired or the max number
of occurrences exceeded.
12.4 4xx Client Error
The 4xx class of status code is intended for cases in which the client seems to have erred.
These status codes are applicable to any request method. User agents SHOULD display any inclu-
ded entity to the user.
12.4.1 400 Bad Request
The request could not be understood by the SSC Server due to malformed syntax. The client
SHOULD NOT repeat the request without modifications.
12.4.2 401 Unauthorized
Error code response for missing or invalid authentication token. The request requires user authen-
tication. If the request already included Authorization credentials, then the 401 response indicates
that authorization has been refused for those credentials.
12.4.3 403 Forbidden
Error code for user not authorized to perform the operation or the resource is unavailable for some
reason (e.g. time constraints, etc.). The SSC Server understood the request, but is refusing to fulfill
it. Authorization will not help and the request SHOULD NOT be repeated.
12.4.4 404 Not Found
The SSC Server has not found anything matching the request. No indication is given of whether the
condition is temporary or permanent. The requested resource could not be found but may be availa-
ble again in the future. Subsequent requests by the client are permissible. Used when the requested
resource is not found, whether it doesn‘t exist or if there was a 401 or 403 that, for security reasons,
the service wants to mask.
12.4.5 406 Not Acceptable (E.g. wrong type for parameter)
The SSC Server is not capable of processing the request, f.i. the client request to change a read
only parameter value.
