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

128 directives will cause a request to
129 <code>DOCUMENT_ROOT/somedir/index.html</code> to look in
130 <code>DOCUMENT_ROOT/somedir/.web/index.html.meta</code> and
131 will use its contents to generate additional MIME header
