The iTP WebServer Architecture
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.
