Apache modules
Modules are service programs that can be dynamically linked and loaded to extend the nature of the HTTP Server.
- Authentication
- Encryption
- Application support
- Logging
- Support for different content types
- Diagnostic support
LoadModule ibm_ssl_module /QSYS.LIB/QHTTPSVR.LIB/QZSRVSSL.SRVPGM
This service program is only loaded, linked, and used when you
configure the LoadModule
directive because you decided
to encrypt your data using Secure Sockets Layer (SSL). The advantage
of this is that the core Apache program can stay relatively small
and tight until a particular function (as provided by a plug-in module)
is needed. Then, with just a LoadModule
directive
and optionally some configuration directives, you can increase the
functionality of your Web server with a corresponding increase in
the working set size.
Apache core functions are those functions available in a standard
Apache installation with no nonstandard modules. The HTTP Server supports
more than a 250 directives. About 30 percent of those directives are
in the core functions. The remainder of the directives are in separate
modules. The LoadModule
directive must be used to
activate the directives in these modules.
- WebSphere® Application Server plug-in
- Forwards HTTP requests from the Web server to WebSphere Application Server. WebSphere Application Server is the premier application server for Java™ applications.
- Integrated Web Application Server plug-in
- Forwards HTTP requests from the Web server to Integrated Web Application Server. Integrated Web Application Server is a lightweight application server for Java applications that is integrated into the IBM i operating system.
You can also write your own module to extend the core functionality of the HTTP Server.
