it is much better to let the server push the messages and client to listen

No it's not. Trust me on this - I spent a lot of time working on a push application back in the late 90s, and the problems that had to be overcome are immense. With a push mechanism, you have to keep track of connected clients and track of what you have sent to the client. Suppose that you get a temporary network outage to a client and you push a message out, you need to track this and take some action based on this - for instance, you may allow a retry interval and then attempt to push the message again.

Remember that connections are finite resources, so you'd have to create a disconnected push mechanism which is a whole magnitude of complexity beyond. There are all sorts of tricks that you have to employ there.

Forgive your enemies - it messes with their heads
