The Apache Web Server

Static Modules

A static module is a module that been compiled into Apache itself, and thus 

cannot be removed. 

The following is a list and brief description of the static modules that have been 

included with your server:

mod_so.c   Allows other modules to be loaded in at run time 

mod_auth_mysql.c   Allows you to restrict access to areas of your Web site 

based on authentication information stored in a MySQL database. 

In our knowledgebase, we have included instructions on using mod_auth_mysql 

on two versions of Apache. Click a link below for the instructions you want to view:

Using mod_auth_mysql on Apache 1.3

Using mod_auth_mysql on Apache 2.0

More information about these and other modules can be found on the Apache 

Web site at 

http://modules.apache.org/

.

Dynamic Modules

A dynamic module, also known as a DSO or Dynamically Shared Object, is a 

module that can be loaded at run time. DSO's are loaded into Apache by placing 

LoadModule and AddModule directives in your /www/conf/httpd.conf file.

Dynamic modules that are loaded by Apache should be stored in the /www/

libexec directory. Your VPS server already provides a number of popular modules 

within this directory. 

Warning! Although you have the power to deactivate each of the 

provided modules by editing your /www/conf/httpd.conf file, we 

strongly recommend that you leave all of the provided modules 

in unless they absolutely must be removed. 

The following is a list of the modules that are provided with your VPS server. With 

the exception of the libperl module, which is found in the /usr/lib/ directory, all the 

modules reside in the /www/libexec directory: 

mod_perl   Allows programs written in Perl to be executed more efficiently from 

Apache. 

mod_php4   A powerful embedded scripting language that can greatly extend the 

functionality of Web pages.

lmod_ssl   Encryption library that makes it possible for your Apache Web server 

to run securely using SSL.
