The SSE Server Hub allows for HTTP Client Requests (through a Rest Expose API) to be persisted for Event Streaming as per protocol¹. This is accomplished by switching the mime-type response to the appropriate text/event-stream and flushing the messages complying to the event source format².

The SSE Client implements the Event Source JS Interface containing the Server Sent Event API, also per protocol³.

Effectively, no third parties are required for Server Push/Messaging.
