onClose event for WebSocket on Reactive stack [SPR-16256]

[spring-projects-issues]

Sola opened SPR-16256 and commented

I've tried doOnTerminate doOnCancel doOnSubscribe on the sending flux, but all of them won't get invoked when a WebSocket connection incoming or closing. I'm wondering how can I get noticed when a WebSocket connection is being closed?

That will be on the receiving Flux, which represents the connection from the server. The sending side is provided and controlled by the application.
