<h3>Summary</h3>

      <p>The index of a directory can come from one of two
      sources:</p>

    <ul>
      <li>A file located in that directory, typically called
      <code>index.html</code>. The <code class="directive"><a href="../mod/mod_dir.html#directoryindex">DirectoryIndex</a></code> directive sets the
      name of the file or files to be used. This is controlled by
      <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code>.</li>

      <li>Otherwise, a listing generated by the server. The other
      directives control the format of this listing. The <code class="directive"><a href="#addicon">AddIcon</a></code>, <code class="directive"><a href="#addiconbyencoding">AddIconByEncoding</a></code> and
      <code class="directive"><a href="#addiconbytype">AddIconByType</a></code> are
      used to set a list of icons to display for various file types;
      for each file listed, the first icon listed that matches the
      file is displayed. These are controlled by
      <code class="module"><a href="../mod/mod_autoindex.html">mod_autoindex</a></code>.</li>
    </ul>
    <p>The two functions are separated so that you can completely
    remove (or replace) automatic index generation should you want
    to.</p>

    <p>Automatic index generation is enabled with using
    <code>Options +Indexes</code>. See the
    <code class="directive"><a href="../mod/core.html#options">Options</a></code> directive for
    more details.</p>

    <p>If the <code><a href="#indexoptions.fancyindexing">FancyIndexing</a></code> option is given with the <code class="directive"><a href="#indexoptions">IndexOptions</a></code> directive,
    the column headers are links that control the order of the
    display. If you select a header link, the listing will be
    regenerated, sorted by the values in that column. Selecting the
    same header repeatedly toggles between ascending and descending
    order. These column header links are suppressed with the
    <code class="directive"><a href="#indexoptions">IndexOptions</a></code> directive's
    <code><a href="#indexoptions.suppresscolumnsorting">SuppressColumnSorting</a></code> 
    option.</p>

    <p>Note that when the display is sorted by "Size", it's the
    <em>actual</em> size of the files that's used, not the
    displayed value - so a 1010-byte file will always be displayed
    before a 1011-byte file (if in ascending order) even though
    they both are shown as "1K".</p>

<h2><a name="query" id="query">Autoindex Request Query Arguments</a></h2>
    

    <p>Various query string arguments are available to give the client
    some control over the ordering of the directory listing, as well as
    what files are listed. If you do not wish to give the client this
    control, the <code><a href="#indexoptions.ignoreclient">IndexOptions
    IgnoreClient</a></code> option disables that functionality.</p>

    <p>The column sorting headers themselves are self-referencing
    hyperlinks that add the sort query options shown below. Any
    option below may be added to any request for the directory
    resource.</p>

    <ul>
      <li><code>C=N</code> sorts the directory by file name</li>

      <li><code>C=M</code> sorts the directory by last-modified
      date, then file name</li>

      <li><code>C=S</code> sorts the directory by size, then file
      name</li>

      <li class="separate"><code>C=D</code> sorts the directory by description, then
      file name</li>

      <li><code>O=A</code> sorts the listing in Ascending
      Order</li>

      <li class="separate"><code>O=D</code> sorts the listing in Descending
      Order</li>

      <li><code>F=0</code> formats the listing as a simple list
      (not FancyIndexed)</li>

      <li><code>F=1</code> formats the listing as a FancyIndexed
      list</li>

      <li class="separate"><code>F=2</code> formats the listing as an
      HTMLTable FancyIndexed list</li>

      <li><code>V=0</code> disables version sorting</li>

      <li class="separate"><code>V=1</code> enables version sorting</li>

      <li><code>P=<var>pattern</var></code> lists only files matching
      the given <var>pattern</var></li>
    </ul>

    <p>Note that the 'P'attern query argument is tested
    <em>after</em> the usual <code class="directive"><a href="#indexignore">IndexIgnore</a></code> directives are processed,
    and all file names are still subjected to the same criteria as
    any other autoindex listing. The Query Arguments parser in
    <code class="module"><a href="../mod/mod_autoindex.html">mod_autoindex</a></code> will stop abruptly when an unrecognized
    option is encountered. The Query Arguments must be well formed,
    according to the table above.</p>

    <p>The simple example below, which can be clipped and saved in
    a header.html file, illustrates these query options. Note that
    the unknown "X" argument, for the submit button, is listed last
    to assure the arguments are all parsed before mod_autoindex
    encounters the X=Go input.</p>

    <div class="example"><p><code>
      &lt;form action="" method="get"&gt;<br />
      <span class="indent">
        Show me a &lt;select name="F"&gt;<br />

    <p>The typical, default description field is 23 bytes wide. 6
    more bytes are added by the <code><a href="#indexoptions.suppressicon">IndexOptions SuppressIcon</a></code> option, 7 bytes are
    added by the <code><a href="#indexoptions.suppresssize">IndexOptions SuppressSize</a></code> option, and 19 bytes are
    added by the <code><a href="#indexoptions.suppresslastmodified">IndexOptions SuppressLastModified</a></code> option.
    Therefore, the widest default the description column is ever
    assigned is 55 bytes.</p>

    <p>Since the <var>File</var> argument may be a partial file name,
    please remember that a too-short partial filename may match
    unintended files. For example, <code>le.html</code> will match the
    file <code>le.html</code> but will also match the file
    <code>example.html</code>. In the event that there may be ambiguity,
    use as complete a filename as you can, but keep in mind that the
    first match encountered will be used, and order your list of
    <code>AddDescription</code> directives accordingly.</p>

    <p>See the <a href="#indexoptions.descriptionwidth">DescriptionWidth</a> <code class="directive"><a href="#indexoptions">IndexOptions</a></code> keyword for details on overriding the size
    of this column, or allowing descriptions of unlimited length.</p>

    <div class="note"><h3>Caution</h3>
      <p>Descriptive text defined with <code class="directive">AddDescription</code>
      may contain HTML markup, such as tags and character entities. If the
      width of the description column should happen to truncate a tagged
      element (such as cutting off the end of a bolded phrase), the
      results may affect the rest of the directory listing.</p>

      prefixed with '*/' to avoid matching partial directory names.</p>

    IndexOptions SuppressColumnsorting

     <p>will be the equivalent of</p>

     </li>

     <li>The addition of the incremental syntax (<em>i.e.</em>, prefixing
     keywords with <code>+</code> or <code>-</code>).</li>
     </ul>

     <p>Whenever a '+' or '-' prefixed keyword is encountered, it
     is applied to the current <code class="directive">IndexOptions</code>
     settings (which may have been inherited from an upper-level
     directory). However, whenever an unprefixed keyword is processed, it
     clears all inherited options and any incremental settings encountered

     <pre class="prettyprint lang-config">IndexOptions +ScanHTMLTitles -IconsAreLinks FancyIndexing
IndexOptions +SuppressSize</pre>


     <p>The net effect is equivalent to <code>IndexOptions FancyIndexing
     +SuppressSize</code>, because the unprefixed <code>FancyIndexing</code>
     discarded the incremental keywords before it, but allowed them to
     start accumulating again afterward.</p>

     <p>To unconditionally set the <code class="directive">IndexOptions</code> for
     a particular directory, clearing the inherited settings, specify
