Netscape Enterprise Server Architecture
Content Engines
Enterprise Server content engines are designed for manipulating customer data.
The following three content engines make up the Web Publishing layer of the
Enterprise Server architecture: HTTP (Web Server), Content Management, and
the Search (Verity).
The HTTP engine represents the core of the Enterprise Web Server. From a
functional perspective, the rest of the Enterprise Server architecture resides on
top of this engine for performance and intergration functionality.
The Content Management engine enables you to manage your server’s
content. You create and store HTML pages, JavaServer Pages, and other files
such as graphics, text, sound, or video on your server. When clients connect to
your server, they can view your files provided they have access to them.
The Search engine enables Enterprise Server users to search the contents and
attributes of documents on the server. As the server administrator, you can
create a customized text search interface that works with various types of
documents formats, such as HTML, Microsoft Word, Adobe PDF, and
WordPerfect. Enterprise Server converts many types of non-HTML documents
into HTML as it indexes them so that users can use your web browser to view
the documents that are found for their search.
Server Extensions
The Enterprise Server 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 Enterprise Server 4.0 architecture:
• Common Gateway Interface (CGI)
• Netscape Server Application Programming Interface (NSAPI)
• Java Servlets and JavaServer Pages
• SHTML & JavaScript
• Web Application Interface (WAI)
Common Gateway Interface (CGI) is a stand-alone application development
interface that enables you to create programs that process your client requests
dynamically.
