When a page is available in multiple representations (for example, if the text is
available in multiple languages, or a file is available in different character sets or
compression formats), the iTP Secure WebServer can select among those
representations on the basis of information transmitted with each request or
specified in the iTP Secure WebServer configuration.
iTP Secure WebServer Architecture
Descriptions of the major components shown in Figure 1-1 follow the figure. For
information about other products you can use in the iTP Secure WebServer
environment, see Other Products for the iTP Secure WebServer Environment on
page 1-10.
Figure 1-1 shows the architecture for a conventional TCP/IP environment.
If you use the new Parallel Library TCP/IP product, the architectural environment
changes slightly. Running with the Auto-Accept feature, an iTP WebServer no longer
needs the Distributor component.The httpd servers will assume the listening as well as
the distributing functions of the Distributor. The Distributor server class will be
completely removed from the PATHWAY environment. All the necessary process hops
will be removed, resulting in a far superior performance.
