•
Flexible access control
You can control access to the iTP Secure WebServer on the basis of such factors
as host name, time of day, user name, browser type and version, and
authentication method.
•
High availability
The iTP Secure WebServer uses HP NonStop TS/MP to ensure high availability.
NonStop TS/MP enables you to run, as a server class, several instances of the
same process. You can configure NonStop TS/MP to create new processes as
workload increases and to restart any process that fails.
•
Extensibility
You can enrich your WebServer environment by creating applications that use CGI,
Java Servlets and JavaServer Pages. The iTP Secure WebServer supports both
conventional CGI applications and persistent applications by using the parallel
processing benefits of NonStop TS/MP. You can write applications in any of several
popular programming languages, including Java. With the companion product iTP
Active Transaction Pages (ATP), you can also use server-side JavaScript to
develop Web-based interfaces for NonStop TS/MP (Pathway), NonStop SQL/MP,
NonStop TUXEDO, and TCP/IP sockets applications.
•
Enhanced logging facilities
The iTP Secure WebServer provides an extended log format (ELF) that includes
the access, error, and security information of each request. ELF also provides
fields for logging the Web client type, the referring URL, and the request begin and
end times. The fields are all labelled, making the fields easy to parse and new
fields easy to add. The server also supports the Common Log Format (CLF) widely
used by other Web servers.
The iTP Secure WebServer does not support the PTrace utility.
•
Enhanced event reporting
The iTP Secure WebServer and many related components report events to the
Event Management Service (EMS). Messages identify the iTP Secure WebServer
subsystem, PATHMON name, and the type of event that occurred.
•
Resource Locator Service (RLS)
This service enables you to define multiple Web servers to be used
interchangeably for access to the same URLs. The requester need not know which
server handled a request.
•
Online-Upgrade
iTP Secure Webserver can be upgraded to a newer version with zero downtime.
The online-upgrade utility allows the iTP Secure WebServer to be upgraded
without bringing the running web server down. This is achieved by bringing one
Pathmon down and upgrading webserver objects with those of the newer version,
