Hi all, I have a net core API hosted on a Linux box on my LAN, its main purpose is to return data from a Postgresql database. Events are raised by Postgresql when specific things occur and I receive these in my controllers via an event listener with a payload. What I wuld like to be able to do , is, pass these events to the callee ( usually my web server which is also hosted on my LAN ) is this doable ? or is there a better way of doing this ?

What I have tried:

I've found a way of recieving notifications from Postgresql ( with a payload ) but can't think of a way to send the data back to the callee IHTMS

The entire HTTP paradigm prevents this. HTTP/HTTPS servers NEVER call the client. You cannot use your normal web API methods to send notifications to the clients. HTTP follows a request/response model. The client makes a request and the server returns the response to it. The server can never just send something to the client if the client didn't request it.

You need an alternate server and communication channel to push updates, like SignalR, or the like.
