<p>This module is used to associate various bits of "meta
information" with files by their filename extensions. This
information relates the filename of the document to it's
mime-type, language, character set and encoding. This
information is sent to the browser, and participates in content
negotiation, so the user's preferences are respected when
choosing one of several possible files to serve. See
<code class="module"><a href="../mod/mod_negotiation.html">mod_negotiation</a></code> for more information
about content negotiation. </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 meta-information for that file. Respectively
they set the character set, content-encoding, content-language,
and MIME-type (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 MIME 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 meta-information
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">&lt;location&gt;</a></code>, <code class="directive"><a href="../mod/core.html#directory">&lt;directory&gt;</a></code>, or <code class="directive"><a href="../mod/core.html#files">&lt;Files&gt;</a></code>) with particular
meta-information. 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 meta-information 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
meta-information (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>

<p>Files can have more than one extension, and the order of the
extensions is <em>normally</em> irrelevant. For example, if the
file <code>welcome.html.fr</code> maps onto content type
text/html 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 which maps onto the same
type of meta-information, then the one to the right will be
used. For example, if ".gif" maps to the MIME-type image/gif
and ".html" maps to the MIME-type text/html, then the file
<code>welcome.gif.html</code> will be associated with the
MIME-type "text/html".</p>
<p>Care should be taken when a file with multiple extensions
gets associated with both a MIME-type and a handler. This will
usually result in the request being by the module associated
with the handler. For example, if the <code>.imap</code>
extension is mapped to the handler "imap-file" (from mod_imap)
and the <code>.html</code> extension is mapped to the MIME-type
"text/html", then the file <code>world.imap.html</code> will be
associated with both the "imap-file" handler and "text/html"
MIME-type. When it is processed, the "imap-file" handler will
be used, and so it will be treated as a mod_imap imagemap
file.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="section"><h2><a name="contentencoding" id="contentencoding">Content encoding</a></h2>
<p>A file of a particular MIME type 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 MIME RFC puts it this way:</p>
<div class="note">
The Content-Encoding entity-header field is used as a
modifier to the media-type. When present, its value indicates
what additional content coding has been applied to the
resource, and thus what decoding mechanism must be applied in
order to obtain the media-type referenced by the Content-Type
header field. The Content-Encoding is primarily used to allow
a document to be compressed without losing the identity of
its underlying media type.
</div>
<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 send a <code>Content-encoding</code> header with the
resource, in order to tell the client browser about the
encoding method.</p>
<div class="example"><p><code>Content-encoding: pkzip</code></p></div>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="section"><h2>Character sets and languages</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="module"><a href="../mod/AddCharset.html">AddCharset</a></code>, <code class="module"><a href="../mod/AddEncoding.html">AddEncoding</a></code>,
<code class="module"><a href="../mod/AddLanguage.html">AddLanguage</a></code> and <code class="module"><a href="../mod/AddType.html">AddType</a></code> directives
(and extensions listed in the <code class="module"><a href="../mod/MimeMagicFile.html">MimeMagicFile</a></code>)
participate in this select process. Filename extensions that
are only associated using the <code class="module"><a href="../mod/AddHandler.html">AddHandler</a></code>,
<code class="module"><a href="../mod/AddInputFilter.html">AddInputFilter</a></code> or <code class="module"><a href="../mod/AddOutputFilter.html">AddOutputFilter</a></code>
directives may be included or excluded from matching by using
the <code class="directive">MultiviewsMatch</code> directive.</p>
<h3>Charset</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<br />
Content-Type: text/plain; charset=ISO-8859-2
</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>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="directive-section"><h2><a name="AddCharset" id="AddCharset">AddCharset</a> <a name="addcharset" id="addcharset">Directive</a></h2><table class="directive"><tr><th><a href="directive-dict.html#Description">Description:

<p>The AddCharset directive maps the given filename extensions
to the specified content charset. <em>charset</em> is the MIME
charset parameter of filenames containing <em>extension</em>.
This mapping is added to any already in force, overriding any
mappings that already exist for the same <em>extension</em>.</p>
<p>Example:</p>
<div class="example"><p><code>
AddLanguage ja .ja<br />
AddCharset EUC-JP .euc<br />
AddCharset ISO-2022-JP .jis<br />
AddCharset SHIFT_JIS .sjis
</code></p></div>
<p>Then the document <code>xxxx.ja.jis</code> will be treated
as being a Japanese document whose charset is ISO-2022-JP (as
will the document <code>xxxx.jis.ja</code>). The AddCharset
directive is useful for both to inform the client about the
character encoding of the document so that the document can be
interpreted and displayed appropriately, and for <a href="../content-negotiation.html">content negotiation</a>,
where the server returns one from several documents based on
the client's charset preference.</p>
<p>The <em>extension</em> argument is case-insensitive, and can
be specified with or without a leading dot.</p>

<p>The AddEncoding directive maps the given filename extensions
to the specified encoding type. <em>MIME-enc</em> is the MIME
encoding to use for documents containing the
<em>extension</em>. This mapping is added to any already in
force, overriding any mappings that already exist for the same
<em>extension</em>. Example:</p>
<div class="example"><p><code>
AddEncoding x-gzip .gz<br />
AddEncoding x-compress .Z
</code></p></div>
<p>This will cause filenames containing the .gz extension to be
marked as encoded using the x-gzip encoding, and filenames
containing the .Z extension to be marked as encoded with
x-compress. </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 <em>extension</em> argument is case-insensitive, and can
be specified with or without a leading dot.</p>
</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="directive-section"><h2><a name="AddHandler" id="AddHandler">AddHandler</a> <a name="addhandler" id="addhandler">Directive</a></h2><table class="directive"><tr><th><a href="directive-dict.html#Description">Description:

<p>Files having the name <em>extension</em> will be served by the
specified <a href="../handler.html">handler-name</a>. This mapping is
added to any already in force, overriding any mappings that already
exist for the same <em>extension</em>. For example, to activate CGI
scripts with the file extension "<code>.cgi</code>", you might
use:</p>
<div class="example"><p><code>
AddHandler cgi-script .cgi
</code></p></div>
<p>Once that has been put into your srm.conf or httpd.conf
file, any file containing the "<code>.cgi</code>" extension
will be treated as a CGI program.</p>
<p>The <em>extension</em> argument is case-insensitive, and can
be specified with or without a leading dot.</p>

<p>The AddLanguage directive maps the given filename extension
to the specified content language. <em>MIME-lang</em> is the
MIME language of filenames containing <em>extension</em>. This
mapping is added to any already in force, overriding any
mappings that already exist for the same

<p>Example:</p>
<div class="example"><p><code>
AddEncoding x-compress .Z<br />
AddLanguage en .en<br />
AddLanguage fr .fr
</code></p></div>
<p>Then the document <code>xxxx.en.Z</code> will be treated as
being a compressed English document (as will the document
<code>xxxx.Z.en</code>). Although the content language is
reported to the client, the browser is unlikely to use this
information. The AddLanguage directive is more useful for <a href="../content-negotiation.html">content negotiation</a>,
where the server returns one from several documents based on
the client's language preference.</p>
<p>If multiple language assignments are made for the same
extension, the last one encountered is the one that is used.
That is, for the case of:</p>
<div class="example"><p><code>
AddLanguage en .en<br />
AddLanguage en-uk .en<br />
AddLanguage en-us .en
</code></p></div>
<p>documents with the extension "<code>.en</code>" would be
treated as being "<code>en-us</code>".</p>

be specified with or without a leading dot.</p>

<p>The AddType directive maps the given filename extensions onto
the specified content type. <em>MIME-type</em> is the MIME type to
use for filenames containing <em>extension</em>. This mapping is
added to any already in force, overriding any mappings that
already exist for the same <em>extension</em>. This directive can
be used to add mappings not listed in the MIME types file (see the
<code class="directive"><a href="#typesconfig">TypesConfig</a></code>
directive).</p>
<p>Example:</p>
<div class="example"><p><code>

<p>The DefaultLanguage directive tells Apache that all files in
the directive's scope (<em>e.g.</em>, all files covered by the
current <code>&lt;Directory&gt;</code> container) that don't
have an explicit language extension (such as <code>.fr</code>
or <code>.de</code> as configured by <code>AddLanguage</code>)
should be considered to be in the specified <em>MIME-lang</em>
language. This allows entire directories to be marked as
containing Dutch content, for instance, without having to
rename each file. Note that unlike using extensions to specify
languages, <code>DefaultLanguage</code> can only specify a
single language.</p>
<p>If no <code>DefaultLanguage</code> directive is in force,
and a file does not have any language extensions as configured
by <code>AddLanguage</code>, then that file will be considered
to have no language attribute.</p>

<p>The ModMimeUsePathInfo directive is used to combine the filename with
the path_info URL component to apply mod_mime's directives to the
request. The default value is 'Off' - therefore, the path_info
component is ignored.
</p>
<p>This directive is recommended when you have a virtual filesystem.</p>
<div class="example"><h3>Example</h3><p><code>
ModMimeUsePathInfo On
</code></p></div>
<p>If you have a request for /bar/foo.shtml where /bar is a Location and
ModMimeUsePathInfo is on, mod_mime will treat the incoming request as
/bar/foo.shtml and directives like
<code>AddOutputFilter INCLUDES .shtml</code> will add the INCLUDES
filter to the request. If ModMimeUsePathInfo is not set, the includes
filter will not be added.

<p>MultiviewsMatch permits three different behaviors for
<a href="mod_negotiation.html">mod_negotiation</a>'s Multiviews
feature. Multiviews allows a request for a file, e.g. index.html,
to match any negotiated extensions following the base request,
e.g. index.html.en, index.html.fr, or index.html.gz.</p>
<p>The NegotiatedOnly option provides that every extension following
the base name must correlate to a recognized mod_mime extension for
content negotation, e.g. 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 MultiviewsMatch directive to either Handlers, Filters, or
both option keywords. If all other factors are equal, the smallest
file will be served, e.g. in deciding between index.html.cgi of 500
characters and index.html.pl of 1000 bytes, the .cgi file would win
in this example. Users of .asis files might prefer to use the
Handler option, if .asis files are associated with the asis-handler.</p>
<p>You may finally allow Any extensions to match, even if mod_mime
doesn't recognize the extension. This was the behavior in Apache 1.3,
and can cause unpredicatable 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>
<div class="example"><p><code>
MultiviewsMatch Handlers Filters
</code></p></div>

<p>The TypesConfig directive sets the location of the MIME types
configuration file. <em>Filename</em> is relative to the <a href="core.html#serverroot">ServerRoot</a>. This file sets the
default list of mappings from filename extensions to content
types. Most administrators use the provided
<code>mime.types</code> file, which associates common filename
extensions with IANA registered content types. The current list is
maintained at
<code>http://www.isi.edu/in-notes/iana/assignments/media-types/media-types</code>. This
simplifies the <code>httpd.conf</code> file by providing the
majority of media-type definitions, and may be overridden by
<code class="directive"><a href="#addtype">AddType</a></code> directives as
needed. You should not edit the <code>mime.types</code> file,
because it may be replaced when you upgrade your server.</p>
