<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">&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
    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>

<div class="section">
<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>

<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>

    <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">DefaultLanguage</code> directive tells Apache
    that all resources in the directive's scope (<em>e.g.</em>, all resources
    covered by the current <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> container) that don't have an explicit language
    extension (such as <code>.fr</code> or <code>.de</code> as configured
    by <code class="directive"><a href="#addlanguage">AddLanguage</a></code>) should be
    assigned a Content-Language of <var>language-tag</var>. This allows
    entire directory trees to be marked as containing Dutch content, for
    instance, without having to rename each file. Note that unlike using
    extensions to specify languages, <code class="directive">DefaultLanguage</code>
    can only specify a single language.</p>

    <p>If no <code class="directive">DefaultLanguage</code> directive is in force
    and a file does not have any language extensions as configured
    by <code class="directive"><a href="#addlanguage">AddLanguage</a></code>, then no
    Content-Language header field will be generated.</p>

    <p>The <code class="directive">ModMimeUsePathInfo</code> directive is used to
    combine the filename with the <code>path_info</code> URL component to
    apply <code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code>'s directives to the request. The default
    value is <code>Off</code> - therefore, the <code>path_info</code>
    component is ignored.</p>

    <p>This directive is recommended when you have a virtual filesystem.</p>

    <div class="example"><h3>Example</h3><pre class="prettyprint lang-config">ModMimeUsePathInfo On</pre>
</div>

    <p>If you have a request for <code>/index.php/foo.shtml</code>
    <code class="module"><a href="../mod/mod_mime.html">mod_mime</a></code> will now treat the
    incoming request as <code>/index.php/foo.shtml</code> and directives
    like <code>AddOutputFilter INCLUDES .shtml</code> will add the
    <code>INCLUDES</code> filter to the request. If <code class="directive">ModMimeUsePathInfo</code> is not set, the
    <code>INCLUDES</code> filter will not be added. This will work
    analogously for virtual paths, such as those defined by
    <code class="directive">&lt;Location&gt;</code></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
    <code class="directive"><a href="../mod/core.html#location">&lt;Location&gt;</a></code> or <code class="directive"><a href="../mod/core.html#locationmatch">&lt;LocationMatch&gt;</a></code> section.</p>
