Server Push

Server Push allows for dynamic document updating via a server to client connection that is kept open. This method (as opposed to Client Pull) is totally controlled by the server, but the perpetual open connection occupies valuable server resources. It's main advantage over Client Pull though, is that using Server Push, it is possible to replace single elements within a HTML document.

The exact Server Push mechanism is technically complex and is outside the scope of this reference. Those that are interested in utilising Server Push in CGI scripts, or web server based executable applications should visit the Netscape site (http://www.netscape.com/) for more information. It should be noted that only Netscape supports the use of Server Push.
