Apache Modules
Apache Modules
are code segments that are written to comply with the Apache API specification and can be loaded into the
Apache Web Server. Apache modules can be loaded in one the following ways.
- Statically loaded in the compiled httpd daemon
- Dynamically loaded in the web server configuration file
This modular design for adding web server features gives web
administrators and developers tremendous power and flexibility.
A wide variety of Apache modules have been created supporting all kinds of exciting web server features.
Web server speed and efficiency is improved when using Apache modules since your Virtual Server web server
can internally process instruction sets rather than relying on external
applications.
Static Apache Modules
The following Apache modules are statically loaded into our
customized Apache Web Server.

Dynamic Apache Modules
Dynamic module support is one of the key features of the Apache Web Server. The ability to
dynamically load modules is known as DSO support. DSO allows you to extend the features and capabilities of
Apache by adding the specific module you need, when you need it, without recompiling the web server
binary.
Some notable dynamic Apache modules include the following.
Use the LoadModule directive in order to load a dynamic module into your Apache Web Server.
The LoadModule should be placed at the top of your web server configuration file
(~/www/conf/httpd.conf). The syntax is like this:
LoadModule MODULE-NAME modules/FILE-NAME
For example, to add the Status Module, add this line:
LoadModule status_module modules/mod_status.so
A complete list of all available dynamic Apache modules appears below.

NOTE:
If you try to load all the modules at the same time you
will probably get a resource error. Simply load the modules you need one
at a time.

Compiling Your Own DSO Modules
Apache 1.3 also supports the APXS
(APache eXtenSion) tool. APXS allows you to compile and link your own dynamic
shared object (DSO) Apache Modules. To use APXS, connect to your Virtual Server via
Telnet or SSH and issue the
following command.
% /usr/local/apache/1.3/bin/apxs OPTIONS MODULE_CODE
