40.4.3 Base and Extension Modules
All base and extension modules are described in detail in the Apache documentation.
Only a brief description of the most important modules is available here. Refer to
http://httpd.apache.org/docs/2.2/mod/
module.
mod_actions
Provides methods to execute a script whenever a certain MIME type (such as
application/pdf), a file with a specific extension (like .rpm), or a certain
request method (such as GET) is requested. This module is enabled by default.
mod_alias
Provides Alias and Redirect directives with which you can map a URl to a
specific directory (Alias) or redirect a requested URL to another location. This
module is enabled by default.
mod_auth*
The authentication modules provide different authentication methods: basic authen-
tication with mod_auth_basic or digest authentication with mod_auth_digest. Digest
authentication in Apache 2.2 is considered experimental.
mod_auth_basic and mod_auth_digest must be combined with an authentication
provider module, mod_authn_* (for example, mod_authn_file for text file–based
authentication) and with an authorization module mod_authz_* (for example,
mod_authz_user for user authorization).
More information about this topic is available in the "Authentication HOWTO" at
http://httpd.apache.org/docs/2.2/howto/auth.html
mod_autoindex
Autoindex generates directory listings when no index file (for example, index
.html) is present. The look and feel of these indexes is configurable. This module
is enabled by default. However, directory listings are disabled by default via the
Options directive—overwrite this setting in your virtual host configuration. The
default configuration file for this module is located at /etc/apache2/mod
_autoindex-defaults.conf.
