a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsyncThis module is contained in the <code>mod_cern_meta.c</code> file, and
a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsyncis not compiled in by default. It provides for CERN httpd metafile
a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsyncsemantics. It is only available in Apache 1.1 and later.

a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsync
a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsyncEmulate the CERN HTTPD Meta file semantics. Meta files are HTTP
a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsyncheaders that can be output in addition to the normal range of headers
a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsyncfor each file accessed. They appear rather like the Apache
7d311ea5bfcbdab3122444f92e7c0d003b3e0baavboxsync.asis files, and are able to provide a crude way of influencing
a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsyncthe Expires: header, as well as providing other curiosities.
a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsyncThere are many ways to manage meta information, this one was
a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsyncchosen because there is already a large number of CERN users
a4b605335b7e6a6ba6d5a301bc96de0e89e4b663vboxsyncwho can exploit this module.
