Also refered to as
SorryServer.   As a

Technically speaking it uses a database to store pages with embeded TCL which are prossed by a page generator before being delived to the client as standard HTML.   Due to a heavy reliance on a cache of already generated web pages, Story Server is nearly worthless for dynamic content.   Story server is based off a product originally designed by CNET
