22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <p>This module is used to assign content metadata to the content
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang selected for an HTTP response by mapping patterns in the
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang URI or filenames to the metadata values. For example, the filename
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang extensions of content files often define the content's Internet
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang media type, language, character set, and content-encoding. This
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang information is sent in HTTP messages containing that content and
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang used in content negotiation when selecting alternatives, such that
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang the user's preferences are respected when choosing one of several

22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang change the value of the <code>Last-Modified</code> header.
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang Thus, previously cached copies may still be used by a client or

22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <p>Files can have more than one extension; the order of the
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang extensions is <em>normally</em> irrelevant. For example, if the
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang file <code>welcome.html.fr</code> maps onto content type
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <code>text/html</code> and language French then the file
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <code>welcome.fr.html</code> will map onto exactly the same
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang information. If more than one extension is given that maps onto
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang the same type of metadata, then the one to the right will
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang be used, except for languages and content encodings. For example,
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang if <code>.gif</code> maps to the <glossary>media-type</glossary>
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <code>image/gif</code> and <code>.html</code> maps to the
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang media-type <code>text/html</code>, then the file
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <code>welcome.gif.html</code> will be associated with the
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <p><a href="#charset-lang">Languages</a> and <a href="#contentencoding"
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang >content encodings</a> are treated accumulative, because one can assign
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang more than one language or encoding to a particular resource. For example,
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang the file <code>welcome.html.en.de</code> will be delivered with
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <code>Content-Language: en, de</code> and <code>Content-Type:
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <p>Care should be taken when a file with multiple extensions
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang gets associated with both a <glossary>media-type</glossary>
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang and a handler. This will
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang usually result in the request being handled by the module associated
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang with the handler. For example, if the <code>.imap</code>
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang extension is mapped to the handler <code>imap-file</code> (from
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <module>mod_imagemap</module>) and the <code>.html</code> extension is
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang mapped to the media-type <code>text/html</code>, then the file
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <code>world.imap.html</code> will be associated with both the
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <code>imap-file</code> handler and <code>text/html</code> media-type.
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang When it is processed, the <code>imap-file</code> handler will be used,
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang and so it will be treated as a <module>mod_imagemap</module> imagemap
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <p>If you would prefer only the last dot-separated part of the
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang filename to be mapped to a particular piece of meta-data, then do
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang not use the <code>Add*</code> directives. For example, if you wish
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang to have the file <code>foo.html.cgi</code> processed as a CGI
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang script, but not the file <code>bar.cgi.html</code>, then instead
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang of using <code>AddHandler cgi-script .cgi</code>, use</p>

22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang might prefer to use the Handler option, if <code>.asis</code> files are

22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang Please do <strong>not</strong> send requests to the Apache HTTP

22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang <code>category/x-subtype</code> requests will be automatically
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang rejected, as will any new two-letter extensions as they will
22a84b8d79248a611e4ba663a268d3c4bed054acQuaker Fang likely conflict later with the already crowded language and
