37    <h2>Summary</h2>
38    <!-- XXX: Should mention other possibilities in Apache: mod_header -->
39    Emulate the CERN HTTPD Meta file semantics. Meta files are HTTP
40    headers that can be output in addition to the normal range of
41    headers for each file accessed. They appear rather like the
42    Apache .asis files, and are able to provide a crude way of
43    influencing the Expires: header, as well as providing other
44    curiosities. There are many ways to manage meta information,
45    this one was chosen because there is already a large number of
46    CERN users who can exploit this module.

128    <p>Specifies the file name suffix for the file containing the
129    meta information. For example, the default values for the two
130    directives will cause a request to
131    <code>DOCUMENT_ROOT/somedir/index.html</code> to look in
132    <code>DOCUMENT_ROOT/somedir/.web/index.html.meta</code> and
133    will use its contents to generate additional MIME header
134    information.</p>
