Hi
In regular request/response between client and server, first a client initiates a request to server, then server responses.
Assume that the server always knows the IP address of its clients (note that clients have dynamic IP address). Is it possible to send data to them without request from clients? By "without request from clients" I mean server must be able to send data to clients whenever wants.
Thanks
