Generally: How to ... Notifications from Server

I'm not sure, if this is the right place.

I have some REST Services. They work very well.
I have many clients on diferent systems, working with the servers.


If one person on one client changes data, the server (service) must inform the other clients (if  the client has registered these kind of changing) that they must refresh the visible data.

Previously, I had a socket connection and it was no problem. But now ...?

Either the client polls every second or I set up a separate socket connection to do this.

Is here any standard solution (with or without a TMS component)?

Many greetings,
Thomas

I have found the sgcWebSockets https://www.esegece.com/

I try to use this next to Sparkle/XData

Maybe TMS can do a cooperation :-)
