> Description: | CERN httpd metafile semantics
> Status: | Extension
> Module Identifier: | cern_meta_module

> ## Summary

> Emulate the CERN HTTPD Meta file semantics. Meta files are HTTP headers that can be output in addition to the normal range of headers for each file accessed. They appear rather like the Apache .asis files, and are able to provide a crude way of influencing the Expires: header, as well as providing other curiosities. There are many ways to manage meta information, this one was chosen because there is already a large number of CERN users who can exploit this module.

> More information on the CERN metafile semantics is available.

> ## Directives

> - MetaDir
> - MetaFiles
> - MetaSuffix

> ## MetaDir Directive

> Description: | Name of the directory to find CERN-style meta information files
> Syntax: | MetaDir directory
> Default: | `MetaDir .web`
> Context: | directory
> Status: | Extension
> Module: | mod_cern_meta

> Specifies the name of the directory in which Apache can find meta information files. The directory is usually a 'hidden' subdirectory of the directory that contains the file being accessed. Set to "`.`" to look in the same directory as the file.

> ## MetaFiles Directive

> Description: | Activates CERN meta-file processing
> Syntax: | MetaFiles on|off
> Default: | `MetaFiles off`
> Context: | directory
> Status: | Extension
> Module: | mod_cern_meta

> Turns on/off Meta file processing on a per-directory basis.

> ## MetaSuffix Directive

> Description: | File name suffix for the file containg CERN-style meta information
> Syntax: | MetaSuffix suffix
> Default: | `MetaSuffix .meta`
> Context: | directory
> Status: | Extension
> Module: | mod_cern_meta

> Specifies the file name suffix for the file containing the meta information. For example, the default values for the two directives will cause a request to `DOCUMENT_ROOT/somedir/index.html` to look in `DOCUMENT_ROOT/somedir/.web/index.html.meta` and will use its contents to generate additional MIME header information.
