programs that programmatically extend the functionality of web-based applications by
providing dynamic content from a webserver to a client browser over the HTTP
protocol.
NSJSP is an extension of that servlet functionality, primarily supplying a template of
static content to be modified with dynamic content from a servlet or other
programmable resource.

version of the iTP Secure WebServer is based on the Java servlet API Specification,
Version 2.2 and JavaServer Pages specification Version 1.1.
