Server Extensions

Web Server extensions enable you to extend or replace the function of the server to better suit your business operations. The following server extensions are part of the core Web Server architecture:

Common Gateway Interface (CGI) is a stand-alone application development interface that enables you to create programs that process your client requests dynamically.

Netscape Server Application Programming Interface (NSAPI) implements the functions and server calls when processing a request. Server Application Functions or SAFs these functions, provide the core and extended functionality of Web Server. They enable the server to process requests and divide the requests into small steps that can be arranged in a variety of ways for speed and flexible configuration.

Java servlets and JavaServer Pages extensions enable all servlet and JSP meta functions, including instantiation, initialization, destruction, access from other components, and configuration management. Servlets and JSP files are reusable Java applications that run on a web server rather than in a web browser.
