#### 6.9.6.2 Behavior

RequestUPSCancellation is used to request to the Origin-Server that the state of a UPS Instance be changed to CANCELED as shown in Figure CC.1.1-1 in PS3.4 . The Origin-Server shall process the request as described by the SCP behavior in Section CC.2.2.3 in PS3.4 .

The request may include a Reason For Cancellation and/or a proposed Procedure Step Discontinuation Reason Code Sequence.

The request may also include a Contact Display Name and/or a Contact URI for the person with whom the cancel request may be discussed.

### Note

An HTTP/1.1 Status Code indicating success means that the Request was accepted, not that the UPS has been canceled. The system performing the UPS is not obliged to honor the request to cancel and in some scenarios, may not even receive notification of the request. See Section CC.2.4 in PS3.4 .

To cancel an IN PROGRESS UPS that the User-Agent is itself performing, the User-Agent shall instead use the ChangeUPSState action as described in Section 6.9.5, “ChangeUPSState”.
