Pathway CGI Server

The Pathway CGI extensions are a set of utility procedures that let you develop CGI

applications as NonStop TS/MP server classes or integrate existing NonStop TS/MP

applications into the iTP Secure WebServer environment.

Generic Common Gateway Interface (CGI) Server

CGI is a standard for applications that interface with web servers. CGI applications can

be written in a variety of computer languages (or scripts) including Perl, C, Korn Shell,

and others. The iTP Secure WebServer provides a generic CGI interface that fully

conforms to the NCSA CGI/1.1 standard. For more information, see Section 8, Using

Common Gateway Interface (CGI) Programs.

Servlet Server Class (SSC)

The Servlet Server Class (SSC), also known as the Web Container, lets you write CGI

applications as Java servlets. The servlets execute in SSC processes, which are

scalable and persistent because they run under NonStop TS/MP.

Resource Locator Service (RLS)

RLS allows the implementation of replicated web servers, to be used interchangeably

and transparently for access to the same content and services. The web servers run

on the same or different platforms; RLS chooses the best-performing server to satisfy

each request.

iTP Secure WebServer Admin httpd

The admin httpd process provides the interface between your web client and the iTP

Secure WebServer Administration Server. It is the same program as the iTP Secure

WebServer httpd but runs in the iTP Secure WebServer Administration PATHMON

environment.

Administration Server

The Administration Server lets you establish and modify configurations, and control

and monitor one or more iTP Secure WebServer environments, from a web client.

Other Products for the iTP Secure WebServer Environment

In addition to the components just described, there are several other products you can

use in the iTP Secure WebServer environment:

•

The iTP Search Engine lets you define collections of ASCII and PDF files and

perform sophisticated searches using a scripting language.

•

The WebReporter lets you analyze log information as part of routine web-server

monitoring, tuning, or troubleshooting.
