Whats the purpose of server push and client pull?
Generally, pages are brought to your screen as a result of your input. You click on a link or an image to request a page. But servers also have the ability to automatically deliver an updated version of a page to your screen. For example, a weather watcher might want to see an updated satellite photo at 15-minute intervals. Netscape provides the Pages Creators and Server Administrators two complementary tools for making this work.
