Description:

The directives provided by mod_access are used in <Directory>,
<Files>, and <Location> sections as well as .htaccess files to control
access to particular parts of the server. Access can be controlled
based on the client hostname, IP address, or other characteristics of
the client request, as captured in environment variables. The Allow
and Deny directives are used to specify which clients are or are not
allowed access to the server, while the Order directive sets the
default access state, and configures how the Allow and Deny directives
interact with each other.
