<H2>Summary</H2>
|
|
|
|
<!-- XXX: Should mention other possibilities in Apache: mod_header -->
|
|
|
|
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.

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 "<CODE>.</CODE>" to look in the same directory as the
|
|
file.

|
|
|
|
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 <CODE>
|
|
DOCUMENT_ROOT/somedir/index.html</CODE> to look in
|
|
<CODE>DOCUMENT_ROOT/somedir/.web/index.html.meta</CODE> and will use
|
|
its contents to generate additional MIME header information.
