AccessConfig directive

Syntax: AccessConfig filename
Default: AccessConfig conf/access.conf
Context: server config, virtual host
Status: core

The server will read this file for more directives after reading the ResourceConfig file. Filename is relative to the ServerRoot. This feature can be disabled using:

AccessConfig /dev/null

Historically, this file only contained <Directory> sections; in fact it can now contain any server directive allowed in the server config context.

Syntax: AccessFileName filename filename ...
Default: AccessFileName .htaccess
Context: server config, virtual host
Status: core
Compatibility: AccessFileName can accept more than one filename only in Apache 1.3 and later

When returning a document to the client the server looks for the first existing access control file from this list of names in every directory of the path to the document, if access control files are enabled for that directory. For example:

AccessFileName .acl

before returning the document /usr/local/web/index.html, the server will read /.acl, /usr/.acl, /usr/local/.acl and /usr/local/web/.acl for directives, unless they have been disabled with

<Directory /> AllowOverride None </Directory>

AddModule directive

Syntax: AddModule module module ...
Context: server config
Status: core
Compatibility: AddModule is only available in Apache 1.2 and later

The server can have modules compiled in which are not actively in use. This directive can be used to enable the use of those modules. The server comes with a pre-loaded list of active modules; this list can be cleared with the ClearModuleList directive.

AllowOverride directive

Syntax: AllowOverride override override ...
Default: AllowOverride All
Context: directory
Status: core

When the server finds an .htaccess file (as specified by AccessFileName) it needs to know which directives declared in that file can override earlier access information.

Override can be set to None, in which case the server will not read the file, All in which case the server will allow all the directives, or one or more of the following:
