798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * This version of mod_cern_meta.c controls Meta File behaviour on a
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * per-directory basis. Previous versions of the module defined behaviour
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * on a per-server basis. The upshot is that you'll need to revisit your
12b42c76672a66c2d4ea7212c14f8f1b5a62b78dTom Gundersen * configuration files in order to make use of the new module.
a8eaaee72a2f06e0fb64fb71de3b71ecba31dafbJan Engelhardt * Emulate the CERN HTTPD Meta file semantics. Meta files are HTTP
57e27ec0ada6775d85a5201cd25e989d92d0a1afZbigniew Jędrzejewski-Szmek * headers that can be output in addition to the normal range of
1ff28eaee33d9d0cee46bd176b6d6f8805c95036Tom Gundersen * headers for each file accessed. They appear rather like the Apache
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * .asis files, and are able to provide a crude way of influencing
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * the Expires: header, as well as providing other curiosities.
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * There are many ways to manage meta information, this one was
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * chosen because there is already a large number of CERN users
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * who can exploit this module. It should be noted that there are probably
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * more sensitive ways of managing the Expires: header specifically.
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * The module obeys the following directives, which can appear
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * in the server's .conf files and in .htaccess files.
102bd40e1ed71c7ab980a90435a1c23d4c786c63Lennart Poettering * MetaFiles <on|off>
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * turns on|off meta file processing for any directory.
1ff28eaee33d9d0cee46bd176b6d6f8805c95036Tom Gundersen * Default value is off
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * # turn on MetaFiles in this directory
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * MetaDir <directory name>
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * specifies the name of the directory in which Apache can find
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * meta information files. The directory is usually a 'hidden'
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * subdirectory of the directory that contains the file being
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * # .meta files are in the *same* directory as the
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * # file being accessed
5256e00e8b9015dd1a976d647fc71dc7efbd8cf8Tom Gundersen * the default is to look in a '.web' subdirectory. This is the
5256e00e8b9015dd1a976d647fc71dc7efbd8cf8Tom Gundersen * same as for CERN 3.+ webservers and behaviour is the same as
5256e00e8b9015dd1a976d647fc71dc7efbd8cf8Tom Gundersen * for the directive:
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * MetaSuffix <meta file suffix>
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * specifies the file name suffix for the file containing the
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * meta information. eg:
5256e00e8b9015dd1a976d647fc71dc7efbd8cf8Tom Gundersen * # our meta files are suffixed with '.cern_meta'
5256e00e8b9015dd1a976d647fc71dc7efbd8cf8Tom Gundersen * MetaSuffix .cern_meta
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * the default is to look for files with the suffix '.meta'. This
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * behaviour is the same as for the directive:
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * MetaSuffix .meta
5256e00e8b9015dd1a976d647fc71dc7efbd8cf8Tom Gundersen * When accessing the file
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * DOCUMENT_ROOT/somedir/index.html
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * this module will look for the file
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * DOCUMENT_ROOT/somedir/.web/index.html.meta
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * and will use its contents to generate additional MIME header
5256e00e8b9015dd1a976d647fc71dc7efbd8cf8Tom Gundersen * For more information on the CERN Meta file semantics see:

798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * 29.Jan.96 pfopen/pfclose instead of fopen/fclose
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * DECLINE when real file not found, we may be checking each
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * of the index.html/index.shtml/index.htm variants and don't
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * need to report missing ones as spurious errors.
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * 31.Jan.96 log_error reports about a malformed .meta file, rather
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * than a script error.
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * 20.Jun.96 MetaFiles <on|off> default off, added, so that module
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * can be configured per-directory. Prior to this the module
798d3a524ea57aaf40cb53858aaa45ec702f012dZbigniew Jędrzejewski-Szmek * was running for each request anywhere on the server, naughty..
