mods-available directory

The /etc/apache2/mods-available directory contains configuration files to both load modules and configure them. The .load files inside this directory contain the Apache Load directives to load the modules into the web server, and the .conf files contain additional configuration directives necessary for the operation of the modules.

Modules are enabled using the a2enmod command. The enabled modules are listed in the /etc/apache2/mods-enabled directory as links to the corresponding modules in the /etc/apache2/mods-available directory. To disable a module, the a2dismod command is used.
