    <p>The <code class="directive">AddCharset</code> directive maps the given
    filename extensions to the specified content charset. <var>charset</var>
    is the <a href="http://www.iana.org/assignments/character-sets">MIME
    charset parameter</a> of 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="example"><h3>Example</h3><p><code>
      AddLanguage ja .ja<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 <code>ISO-2022-JP</code>
    (as will the document <code>xxxx.jis.ja</code>). The
    <code class="directive">AddCharset</code> 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 <var>extension</var> argument is case-insensitive, and can

    <p>The <code class="directive">AddEncoding</code> directive maps the given
    filename extensions to the specified encoding type. <var>MIME-enc</var>
    is the MIME encoding to use for documents containing 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><p><code>
      AddEncoding x-gzip .gz<br />
      AddEncoding x-compress .Z
    </code></p></div>

    <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 <var>extension</var> argument is case-insensitive, and can
    be specified with or without a leading dot.</p>

    activate CGI scripts with the file extension <code>.cgi</code>, you
    might use:</p>

    <div class="example"><p><code>

    <p>The <code class="directive">AddLanguage</code> directive maps the given
