There is no method. You have to poll every x seconds to check, if there
is new information available. Netscape and Mozilla implemented an
alternative way, but this is neither standard nor recommended to be used.

Did you try <https://blueimp.net/ajax/>?

Only, if the server is configured to respond on port 80. A web server
can also use other ports.
