Configuring and Managing MPE/iX Internet Services (July 2001)

Apache for MPE/iX
Feature Set
Rewrite
URLs can be translated on-the-fly to new addresses. A
complex set of translation rules allows server variables,
environment variables, HTTP headers, time stamps,
and other values to be used in these address
translations.
Virtual Hosts (Vhost)
A single copy of the Apache web server can be made to
look like multiple web servers by using virtual hosts.
Each alias IP address and alias name that resolves to
your web server’s actual IP address can be configured
as its own virtual host with its own directives (such as
its own document root). It is usually easier to register
additional server names (for name-based virtual hosts)
than to acquire additional IP addresses (for IP-based
virtual hosts) and name-based virtual hosts are the
preferred method. With Apache, large numbers of
virtual hosts can be added and/or configured without
restarting Apache.
Digest Authentication
Digest Authentication is a new authentication scheme
under consideration for web browsers. Web browsers
currently implement Basic Authentication.
Dynamic Shared Objects (DSOs)
DSOs are pieces of program code in a special format for
loading at runtime into the address space of the Apache
program. With DSOs, Apache functionality can easily
be extended with third-party modules without
recompiling the Apache binary.
