6.7 Ignoring HTTP Responses for Notifications to non-oneM2M Entitites
In TS-0004 [3], clause 7.3.1.3 specifies that an originator shall not wait for the Response primitive from the receiver after sending a Notification request to a non-oneM2M entity. If such a Notification is delivered through the CSE’s HTTP binding then the HTTP response message from the Notification’s receiver shall be ignored.
