Does anyone know if there is a way to make the type of server used for standard websites to send data to a known IP address?
I want a client to visit a php page (using client software not browser), and then (in any way possible) have the client not connect to the server again, but instead have the server send data to client's listening port after some time.
Say it is one expensive deticated server with most of things installed (JAVA, PHP, ASP, etc). Or in the other case, what would be minimum requirements?
Maybe I could simply put a delay in the php script but then it would have to keep checking if the variable needed has changed and to send it to the client, which i dont want to do, so i need an "active" way of sending data.
Any help please?
