iTP Secure WebServer httpd

The iTP Secure WebServer httpd has two main functions:

•

A file server. The httpd process transfers and stores files, such as HTML documents.

•

A message-switching facility. The httpd process forwards messages from web

clients to application programs.

The httpd process is implemented as a server class in NonStop TS/MP. Therefore

multiple httpd processes can execute in parallel; the number of processes fluctuates

automatically in response to changes in workload. NonStop TS/MP can also restart a

server process that fails. (The iTP Secure WebServer uses the default value of the

PATHCOM AUTORESTART parameter.)

PATHMON Process

The PATHMON process provides centralized monitoring and control of a PATHMON

environment consisting of server classes and other types of objects. You establish the

operational parameters for the PATHMON environment, including the characteristics of

individual server classes, by creating a PATHMON configuration file. Thereafter, you

can use the PATHCOM utility to make configuration changes and obtain information

from the PATHMON process.

Multiple PATHMON environments can run on the same NonStop system. For example,

the iTP Secure WebServer Administration Server has its own PATHMON environment,

separate from the iTP Secure WebServers environments it manages. (If you have

multiple iTP Secure WebServer environments on the same system, you still need only

one PATHMON environment for the Administration Server.) Each PATHMON

environment has a separate, uniquely named PATHMON process.

WebSafe2 Interface Driver (WID)

A WID is required when you are using the WebSafe2 unit to perform hardware

encryption.

Active Transaction Pages (ATP)

Active Transaction Pages (ATP) provides a server-side JavaScript environment for

Compaq NonStop Systems. You can use ATP objects to provide web-based interfaces to

existing NonStop TS/MP, NonStop TUXEDO, NonStop SQL/MP, and sockets

applications.

See the iTP Active Transaction Pages (iTP ATP) Programmer’s Guide for further

information.

Note. The iTP Secure WebServer does not support Microsoft Active Server Pages or ADO.
