<h3>Summary</h3>
<p>This module is used to assign content metadata to the content
selected for an HTTP response by mapping patterns in the
URI or filenames to the metadata values. For example, the filename
extensions of content files often define the content's Internet
media type, language, character set, and content-encoding. This
information is sent in HTTP messages containing that content and
used in content negotiation when selecting alternatives, such that
the user's preferences are respected when choosing one of several
possible contents to serve. See
<code class="module"><a href="../mod/mod_negotiation.html">mod_negotiation</a></code> for more information
about <a href="../content-negotiation.html">content negotiation</a>.</p>
<p>The directives <code class="directive"><a href="#addcharset">AddCharset</a></code>, <code class="directive"><a href="#addencoding">AddEncoding</a></code>, <code class="directive"><a href="#addlanguage">AddLanguage</a></code> and <code class="directive"><a href="#addtype">AddType</a></code> are all used to map file
extensions onto the metadata for that file. Respectively
they set the character set, content-encoding, content-language,
and <a class="glossarylink" href="../glossary.html#media-type" title="see glossary">media-type</a> (content-type) of documents. The directive <code class="directive"><a href="#typesconfig">TypesConfig</a></code> is used to specify a
file which also maps extensions onto media types. </p>
<p>In addition, <code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code> may define the <a href="../handler.html">handler</a> and <a href="../filter.html">filters</a> that originate and process
content. The directives <code class="directive"><a href="#addhandler">AddHandler</a></code>, <code class="directive"><a href="#addoutputfilter">AddOutputFilter</a></code>, and <code class="directive"><a href="#addinputfilter">AddInputFilter</a></code> control the modules
or scripts that serve the document. The <code class="directive"><a href="#multiviewsmatch">MultiviewsMatch</a></code> directive allows
<code class="module"><a href="../mod/mod_negotiation.html">mod_negotiation</a></code> to consider these file extensions
to be included when testing Multiviews matches.</p>
<p>While <code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code> associates metadata
with filename extensions, the <code class="module"><a href="../mod/core.html">core</a></code> server
provides directives that are used to associate all the files in a
given container (<em>e.g.</em>, <code class="directive"><a href="../mod/core.html#location"><Location></a></code>, <code class="directive"><a href="../mod/core.html#directory"><Directory></a></code>, or <code class="directive"><a href="../mod/core.html#files"><Files></a></code>) with particular
metadata. These directives include <code class="directive"><a href="../mod/core.html#forcetype">ForceType</a></code>, <code class="directive"><a href="../mod/core.html#sethandler">SetHandler</a></code>, <code class="directive"><a href="../mod/core.html#setinputfilter">SetInputFilter</a></code>, and <code class="directive"><a href="../mod/core.html#setoutputfilter">SetOutputFilter</a></code>. The core directives
override any filename extension mappings defined in
<code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code>.</p>
<p>Note that changing the metadata for a file does not
change the value of the <code>Last-Modified</code> header.
Thus, previously cached copies may still be used by a client or
proxy, with the previous headers. If you change the
metadata (language, content type, character set or
encoding) you may need to 'touch' affected files (updating
their last modified date) to ensure that all visitors are
receive the corrected content headers.</p>

<h2><a name="multipleext" id="multipleext">Files with Multiple Extensions</a></h2>
<p>Files can have more than one extension; the order of the
extensions is <em>normally</em> irrelevant. For example, if the
file <code>welcome.html.fr</code> maps onto content type
<code>text/html</code> and language French then the file
<code>welcome.fr.html</code> will map onto exactly the same
information. If more than one extension is given that maps onto
the same type of metadata, then the one to the right will
be used, except for languages and content encodings. For example,
if <code>.gif</code> maps to the <a class="glossarylink" href="../glossary.html#media-type" title="see glossary">media-type</a>
<code>image/gif</code> and <code>.html</code> maps to the
media-type <code>text/html</code>, then the file
<code>welcome.gif.html</code> will be associated with the
media-type <code>text/html</code>.</p>
<p><a href="#charset-lang">Languages</a> and <a href="#contentencoding">content encodings</a> are treated accumulative, because one can assign
more than one language or encoding to a particular resource. For example,
the file <code>welcome.html.en.de</code> will be delivered with
<code>Content-Language: en, de</code> and <code>Content-Type:
text/html</code>.</p>
<p>Care should be taken when a file with multiple extensions
gets associated with both a <a class="glossarylink" href="../glossary.html#media-type" title="see glossary">media-type</a>
and a handler. This will
usually result in the request being handled by the module associated
with the handler. For example, if the <code>.imap</code>
extension is mapped to the handler <code>imap-file</code> (from
<code class="module"><a href="../mod/mod_imagemap.html">mod_imagemap</a></code>) and the <code>.html</code> extension is
mapped to the media-type <code>text/html</code>, then the file
<code>world.imap.html</code> will be associated with both the
<code>imap-file</code> handler and <code>text/html</code> media-type.
When it is processed, the <code>imap-file</code> handler will be used,
and so it will be treated as a <code class="module"><a href="../mod/mod_imagemap.html">mod_imagemap</a></code> imagemap
file.</p>
<p>If you would prefer only the last dot-separated part of the
filename to be mapped to a particular piece of meta-data, then do
not use the <code>Add*</code> directives. For example, if you wish
to have the file <code>foo.html.cgi</code> processed as a CGI
script, but not the file <code>bar.cgi.html</code>, then instead
of using <code>AddHandler cgi-script .cgi</code>, use</p>
<div class="example"><h3>Configure handler based on final extension only</h3><pre class="prettyprint lang-config"><FilesMatch "[^.]+\.cgi$">
SetHandler cgi-script
</FilesMatch></pre>

<h2><a name="contentencoding" id="contentencoding">Content encoding</a></h2>
<p>A file of a particular <a class="glossarylink" href="../glossary.html#media-type" title="see glossary">media-type</a> can additionally be encoded a
particular way to simplify transmission over the Internet.
While this usually will refer to compression, such as
<code>gzip</code>, it can also refer to encryption, such a
<code>pgp</code> or to an encoding such as UUencoding, which is
designed for transmitting a binary file in an ASCII (text)
format.</p>
<p>The <a href="http://www.ietf.org/rfc/rfc2616.txt">HTTP/1.1
RFC</a>, section 14.11 puts it this way:</p>
<blockquote cite="http://www.ietf.org/rfc/rfc2616.txt">
<p>The Content-Encoding entity-header field is used as a modifier to
the media-type. When present, its value indicates what additional
content codings have been applied to the entity-body, and thus what
decoding mechanisms must be applied in order to obtain the media-type
referenced by the Content-Type header field. Content-Encoding is
primarily used to allow a document to be compressed without losing
the identity of its underlying media type.</p>
</blockquote>
<p>By using more than one file extension (see <a href="#multipleext">section above about multiple file
extensions</a>), you can indicate that a file is of a
particular <em>type</em>, and also has a particular
<em>encoding</em>. </p>
<p>For example, you may have a file which is a Microsoft Word
document, which is pkzipped to reduce its size. If the
<code>.doc</code> extension is associated with the Microsoft
Word file type, and the <code>.zip</code> extension is
associated with the pkzip file encoding, then the file
<code>Resume.doc.zip</code> would be known to be a pkzip'ed Word
document.</p>
<p>Apache sends a <code>Content-encoding</code> header with the
resource, in order to tell the client browser about the
encoding method.</p>
<pre class="prettyprint lang-config">Content-encoding: pkzip</pre>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="section">
<h2><a name="charset-lang" id="charset-lang">Character sets and languages</a></h2>
<p>In addition to file type and the file encoding,
another important piece of information is what language a
particular document is in, and in what character set the file
should be displayed. For example, the document might be written
in the Vietnamese alphabet, or in Cyrillic, and should be
displayed as such. This information, also, is transmitted in
HTTP headers.</p>
<p>The character set, language, encoding and mime type are all
used in the process of content negotiation (See
<code class="module"><a href="../mod/mod_negotiation.html">mod_negotiation</a></code>) to determine
which document to give to the client, when there are
alternative documents in more than one character set, language,
encoding or mime type. All filename extensions associations
created with <code class="directive"><a href="#addcharset">AddCharset</a></code>,
<code class="directive"><a href="#addencoding">AddEncoding</a></code>, <code class="directive"><a href="#addlanguage">AddLanguage</a></code> and <code class="directive"><a href="#addtype">AddType</a></code> directives
(and extensions listed in the <code class="directive"><a href="../mod/mod_mime_magic.html#mimemagicfile">MimeMagicFile</a></code>) participate in this select process.
Filename extensions that are only associated using the <code class="directive"><a href="#addhandler">AddHandler</a></code>, <code class="directive"><a href="#addinputfilter">AddInputFilter</a></code> or <code class="directive"><a href="#addoutputfilter">AddOutputFilter</a></code> directives may be included or excluded
from matching by using the <code class="directive"><a href="#multiviewsmatch">MultiviewsMatch</a></code> directive.</p>
<h3><a name="charset" id="charset">Charset</a></h3>
<p>To convey this further information, Apache optionally sends
a <code>Content-Language</code> header, to specify the language
that the document is in, and can append additional information
onto the <code>Content-Type</code> header to indicate the
particular character set that should be used to correctly
render the information.</p>
<div class="example"><p><code>
Content-Language: en, fr
Content-Type: text/plain; charset=ISO-8859-1
</code></p></div>
<p>The language specification is the two-letter abbreviation
for the language. The <code>charset</code> is the name of the
particular character set which should be used.</p>

where the server returns one from several documents based on
the client's charset preference.</p>

<p>The <code class="directive">AddEncoding</code> directive maps the given
filename extensions to the specified HTTP content-encoding.
<var>encoding</var> is the HTTP content coding to append to the
value of the Content-Encoding header field for documents named with the
<var>extension</var>. This mapping is added to any already in force,
overriding any mappings that already exist for the same
<var>extension</var>.</p>
<div class="example"><h3>Example</h3><pre class="prettyprint lang-config">AddEncoding x-gzip .gz
AddEncoding x-compress .Z</pre>

<p>This will cause filenames containing the <code>.gz</code> extension
to be marked as encoded using the <code>x-gzip</code> encoding, and
filenames containing the <code>.Z</code> extension to be marked as
encoded with <code>x-compress</code>.</p>
<p>Old clients expect <code>x-gzip</code> and <code>x-compress</code>,
however the standard dictates that they're equivalent to
<code>gzip</code> and <code>compress</code> respectively. Apache does
content encoding comparisons by ignoring any leading <code>x-</code>.
When responding with an encoding Apache will use whatever form
(<em>i.e.</em>, <code>x-foo</code> or <code>foo</code>) the
client requested. If the client didn't specifically request a
particular form Apache will use the form given by the
<code>AddEncoding</code> directive. To make this long story
short, you should always use <code>x-gzip</code> and
<code>x-compress</code> for these two specific encodings. More
recent encodings, such as <code>deflate</code>, should be
specified without the <code>x-</code>.</p>

<p>The <code class="directive">AddType</code> directive maps the given
filename extensions onto the specified content
type. <var>media-type</var> is the <a class="glossarylink" href="../glossary.html#media-type" title="see glossary">media
type</a> to use for filenames containing
<var>extension</var>. This mapping is added to any already in
force, overriding any mappings that already exist for the same
<var>extension</var>.</p>
<div class="note">
It is recommended that new media types be added using the
<code class="directive">AddType</code> directive rather than changing the
<code class="directive"><a href="#typesconfig">TypesConfig</a></code> file.
</div>
<div class="example"><h3>Example</h3><pre class="prettyprint lang-config">AddType image/gif .gif</pre>
</div>
<p>Or, to specify multiple file extensions in one directive:</p>
<div class="example"><h3>Example</h3><pre class="prettyprint lang-config">AddType image/jpeg jpeg jpg jpe</pre>
</div>
<p>The <var>extension</var> argument is case-insensitive and can
be specified with or without a leading dot. Filenames may have <a href="#multipleext">multiple extensions</a> and the
<var>extension</var> argument will be compared against each of
them.</p>
<p>A similar effect to <code class="module"><a href="../mod/mod_negotiation.html">mod_negotiation</a></code>'s
<code class="directive"><a href="../mod/mod_negotiation.html#languagepriority">LanguagePriority</a></code>
can be achieved by qualifying a <var>media-type</var> with
<code>qs</code>:</p>
<div class="example"><h3>Example</h3><pre class="prettyprint lang-config">AddType application/rss+xml;qs=0.8 .xml</pre>
</div>
<p>This is useful in situations, <em>e.g.</em> when a client
requesting <code>Accept: */*</code> can not actually processes
the content returned by the server.</p>
<p>This directive primarily configures the content types generated for
static files served out of the filesystem. For resources other than
static files, where the generator of the response typically specifies
a Content-Type, this directive has no effect.</p>
<div class="note"><h3>Note</h3>
<p>If no handler is explicitly set for a request, the specified content
type will also be used as the handler name. </p>
<p>When explicit directives such as
<code class="directive"><a href="../mod/core.html#sethandler">SetHandler</a></code> or
<code class="directive"><a href="#addhandler">AddHandler</a></code> do not apply
to the current request, the internal handler name normally set by those
directives is instead set to the content type specified by this directive.
</p>
<p>
This is a historical behavior that may be used by some third-party modules
(such as mod_php) for taking responsibility for the matching request.
</p>
<p>Configurations that rely on such "synthetic" types should be avoided.
Additionally, configurations that restrict access to
<code class="directive"><a href="../mod/core.html#sethandler">SetHandler</a></code> or
<code class="directive"><a href="#addhandler">AddHandler</a></code> should
restrict access to this directive as well.</p>

<p><code class="directive">MultiviewsMatch</code> permits three different
behaviors for <a href="mod_negotiation.html">mod_negotiation</a>'s
Multiviews feature. Multiviews allows a request for a file,
<em>e.g.</em> <code>index.html</code>, to match any negotiated
extensions following the base request, <em>e.g.</em>
<code>index.html.en</code>, <code>index.html.fr</code>, or
<code>index.html.gz</code>.</p>
<p>The <code>NegotiatedOnly</code> option provides that every extension
following the base name must correlate to a recognized
<code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code> extension for content negotiation, <em>e.g.</em>
Charset, Content-Type, Language, or Encoding. This is the strictest
implementation with the fewest unexpected side effects, and is the
default behavior.</p>
<p>To include extensions associated with Handlers and/or Filters,
set the <code class="directive">MultiviewsMatch</code> directive to either
<code>Handlers</code>, <code>Filters</code>, or both option keywords.
If all other factors are equal, the smallest file will be served,
<em>e.g.</em> in deciding between <code>index.html.cgi</code> of 500
bytes and <code>index.html.pl</code> of 1000 bytes, the <code>.cgi</code>
file would win in this example. Users of <code>.asis</code> files
might prefer to use the Handler option, if <code>.asis</code> files are
associated with the <code>asis-handler</code>.</p>
<p>You may finally allow <code>Any</code> extensions to match, even if
<code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code> doesn't recognize the extension. This can cause
unpredictable results, such as serving .old or .bak files the webmaster
never expected to be served.</p>
<p>For example, the following configuration will allow handlers
and filters to participate in Multviews, but will exclude unknown
files:</p>
<pre class="prettyprint lang-config">MultiviewsMatch Handlers Filters</pre>
<p><code class="directive">MultiviewsMatch</code> is not allowed in a

the default list of mappings from filename extensions to content

extensions with the official list of IANA registered media types
maintained at <a href="http://www.iana.org/assignments/media-types/index.html">http://www.iana.org/assignments/media-types/index.html</a>

simplifies the <code>httpd.conf</code> file by providing the
majority of media-type definitions, and may be overridden by

needed. You should not edit the <code>mime.types</code> file,

<p>The case of the extension does not matter. Blank lines, and lines

Empty lines are there for completeness (of the mime.types file).
Apache httpd can still determine these types with <code class="module"><a href="../mod/mod_mime_magic.html">mod_mime_magic</a></code>.

Please do <strong>not</strong> send requests to the Apache HTTP
Server Project to add any new entries in the distributed

registered with IANA, and (2) they use widely accepted,
non-conflicting filename extensions across platforms.
<code>category/x-subtype</code> requests will be automatically
rejected, as will any new two-letter extensions as they will
likely conflict later with the already crowded language and
character set namespace.
