    This module provides for automatic directory indexing.

    <h2>Summary</h2>
    The index of a directory can come from one of two sources: 

    <ul>
      <li>A file written by the user, typically called
      <code>index.html</code>. The <a
      href="mod_dir.html#directoryindex">DirectoryIndex</a>
      directive sets the name of this file. This is controlled by
      <a href="mod_dir.html"><code>mod_dir</code></a>.</li>

      <li>Otherwise, a listing generated by the server. The other
      directives control the format of this listing. The <a
      href="#addicon">AddIcon</a>, <a
      href="#addiconbyencoding">AddIconByEncoding</a> and <a
      href="#addiconbytype">AddIconByType</a> 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>mod_autoindex</code>.</li>
    </ul>
    The two functions are separated so that you can completely
    remove (or replace) automatic index generation should you want
    to. 

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

    <p>If <a href="#fancyindexing"><samp>FancyIndexing</samp></a>
    is enabled, or the <samp>FancyIndexing</samp> keyword is
    present on the <a
    href="#indexoptions"><samp>IndexOptions</samp></a> 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.</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>

    href="mod_dir.html#directoryindex">DirectoryIndex</a>.</p>

    <h2>Autoindex Request Query Arguments</h2>

    <p>The column sorting headers themselves are self-referencing
    hyperlinks that add the sort query options to reorder the
    directory listing. The query options are of the form
    <samp>X=Y</samp>, where <samp>X</samp> is one of <samp>N</samp>
    (file <em>N</em>ame), <samp>M</samp> (file last
    <em>M</em>odified date), <samp>S</samp> (file <em>S</em>ize), or
    <samp>D</samp> (file <em>D</em>escription), and <samp>Y</samp>
    is one of <samp>A</samp> (<em>A</em>scending) or <samp>D</samp>
    (<em>D</em>escending).</p>

    <p>When options other than the file name are used as the
    sorting key, the secondary key is always the file name. (When
    the file name is used to sort by, there is no need of a
    secondary sort key, since file names are guaranteed to be
    unique, and so the sort order is unambiguous.)</p>

    <p>Example:</p>

    <p>If the URL <samp>http://your.server.name/foo/</samp>
    produces a directory index, then the following URLs will
    produce different sort orders:</p>

    <ul>
      <li><samp>http://your.server.name/foo/?M=D</samp> sorts the
      directory by last modified date, descending.</li>

      <li><samp>http://your.server.name/foo/?D=A</samp> sorts the
      directory by file description, ascending.</li>

      <li><samp>http://your.server.name/foo/?S=A</samp> sorts the
      directory by file size, ascending.</li>
    </ul>

    <p>See <a
    href="#indexorderdefault"><samp>IndexOrderDefault</samp></a> to
    set the default directory ordering.</p>

    <p>Note also that when the directory listing is ordered in one
    direction (ascending or descending) by a particular column, the
    link at the top of that column then reverses, to allow sorting
    in the opposite direction by that same column.</p>

    <blockquote>
      <code>AddDescription "The planet Mars"
      /web/pics/mars.gif</code>

    <p>The description field is 23 bytes wide. 7 more bytes may be
    added if the directory is covered by an
    <code>IndexOptions&nbsp;SuppressSize</code>, and 19 bytes may
    be added if <code>IndexOptions&nbsp;SuppressLastModified</code>
    is in effect. The widest this column can be is therefore 49

    <blockquote>
      As of Apache 1.3.10, the <a

    </blockquote>
    <b>Caution:</b> Descriptive text defined with
    <samp>AddDescription</samp> 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>The HeaderName directive sets the name of the file that will
    be inserted at the top of the index listing. <em>Filename</em>
    is the name of the file to include.</p>

      <p>
      <em>Filename</em> is treated as a URI path relative to the
      one used to access the directory being indexed. Note that this
      means that if <em>Filename</em> starts with a slash, it will be
      taken to be relative to the <a
      href="core.html#documentroot">DocumentRoot</a>.</p>
      
      <p><em>Filename</em> must
      resolve to a document with a major content type of
      "<samp>text</samp>" (<em>e.g.</em>, <samp>text/html</samp>,
      <samp>text/plain</samp>, <em>etc.</em>). This means that
      <em>filename</em> may refer to a CGI script if the script's
      actual file type (as opposed to its output) is marked as
      <samp>text/html</samp> such as with a directive like: </p>

<pre>
    AddType text/html .cgi

      document (not a CGI script) and the <samp>Includes</samp> <a
      href="core.html#options">option</a> is enabled, the file will
      be processed for server-side includes (see the <a
      href="mod_include.html"><samp>mod_include</samp></a>
      documentation).

    <p>If the file specified by <samp>HeaderName</samp> contains
    the beginnings of an HTML document (&lt;HTML&gt;, &lt;HEAD&gt;,
    etc) then you will probably want to set <a
    href="#indexoptions:suppresshtmlpreamble"><samp>IndexOptions
    +SuppressHTMLPreamble</samp></a>, so that these tags are not
    repeated.</p>

    <blockquote>
      <strong>Apache 1.3.6 and earlier:</strong> The module first
      attempts to include <em>filename</em><code>.html</code> as an
      HTML document, otherwise it will try to include
      <em>filename</em> as plain text. <em>Filename</em> is treated
      as a filesystem path relative to the directory being indexed.
      In no case is SSI processing done. Example: 

      <blockquote>
        <code>HeaderName HEADER</code>
      </blockquote>
      when indexing the directory <code>/web</code>, the server
      will first look for the HTML file
      <code>/web/HEADER.html</code> and include it if found,
      otherwise it will include the plain text file

    files to ignore. Multiple IndexIgnore directives add to the
    list, rather than replacing the list of ignored files. By
    default, the list contains `<code>.</code>'. Example:</p>

      <dd>If this option is enabled, subdirectories in a
      FancyIndexed listing will <i>always</i> appear first,
      followed by normal files in the directory. The listing is
      basically broken into two components, the files and the
      subdirectories, and each is sorted separately and then
      displayed subdirectories-first. For instance, if the sort
      order is descending by name, and <samp>FoldersFirst</samp> is
      enabled, subdirectory <samp>Zed</samp> will be listed before
      subdirectory <samp>Beta</samp>, which will be listed before

      Presence of this option, when used with IconWidth, will cause

      If this option is enabled, names are sorted in case-insensitive

      and <samp>IgnoreCase</samp> is enabled, file <samp>Zeta</samp>
      will be listed after file <samp>alfa</samp> (Note: file
      <samp>GAMMA</samp> will always be listed before file
      <samp>gamma</samp>). <b>This option only has an effect if <a

      This enables the extraction of the title from HTML documents
      for fancy indexing. If the file does not have a description
      given by <a href="#adddescription">AddDescription</a> then
      httpd will read the document for the value of the TITLE tag.
      This is CPU and disk intensive.</dd>

      <dt><a id="indexoptions:suppresscolumnsorting"
      name="indexoptions:suppresscolumnsorting">SuppressColumnSorting</a></dt>

      <dd>

      If specified, Apache will not make the column headings in a
      FancyIndexed directory listing into links for sorting. The
      default behavior is for them to be links; selecting the
      column heading will sort the directory listing by the values
      in that column. <strong>Only available in Apache 1.3 and
      later.</strong></dd>

      <dt><a id="indexoptions:suppressdescription"
      name="indexoptions:suppressdescription">SuppressDescription</a></dt>

      <dd>

      This will suppress the file description in fancy indexing
      listings. By default, no file descriptions are defined, and
      so the use of this option will regain 23 characters of screen
      space to use for something else. See <a
      href="#adddescription"><samp>AddDescription</samp></a> for
      information about setting the file description. See also the
      <a

      column.</dd>

      <dt><a id="indexoptions:suppresshtmlpreamble"
      name="indexoptions:suppresshtmlpreamble">SuppressHTMLPreamble</a>
      (<em>Apache 1.3 and later</em>)</dt>

      <dd>

      If the directory actually contains a file specified by the <a
      href="#headername">HeaderName</a> directive, the module
      usually includes the contents of the file after a standard
      HTML preamble (&lt;HTML&gt;, &lt;HEAD&gt;, <em>et
      cetera</em>). The SuppressHTMLPreamble option disables this
      behavior, causing the module to start the display with the
      header file contents. The header file must contain
      appropriate HTML instructions in this case. If there is no
      header file, the preamble is generated as usual.</dd>

      <dt><a id="indexoptions:suppresslastmodified"
      name="indexoptions:suppresslastmodified">SuppressLastModified</a></dt>

      <dd>

      This will suppress the display of the last modification date,
      in fancy indexing listings.</dd>

      <dt><a id="indexoptions:suppresssize"
      name="indexoptions:suppresssize">SuppressSize</a></dt>

      <dd>

      This will suppress the file size in fancy indexing
      listings.</dd>

      <dt><a id="indexoptions:trackmodified"
      name="indexoptions:trackmodified">TrackModified (<em>Apache
      1.3.15 and later</em>)</a></dt>

      <dd>

      This returns the Last-Modified and ETag values for the listed
      directory in the HTTP header. It is only valid if the
      operating system and file system return legitimate stat()
      results. Most Unix systems do so, as do OS2's JFS and Win32's
      NTFS volumes. OS2 and Win32 FAT volumes, for example, do not.
      Once this feature is enabled, the client or proxy can track
      changes to the list of files when they perform a HEAD
      request. Note some operating systems correctly track new and
      removed files, but do not track changes for sizes or dates of
      the files within the directory.</dd>
    </dl>

    <p>There are some noticeable differences in the behavior of
    this directive in recent (post-1.3.0) versions of Apache.</p>

    <dl>
      <dt>Apache 1.3.2 and earlier:</dt>

      <dd>
        <p>The default is that no options are enabled. If multiple
        IndexOptions could apply to a directory, then the most
        specific one is taken complete; the options are not merged.
        For example:</p>

        <blockquote>
<pre>
&lt;Directory /web/docs&gt;
    IndexOptions FancyIndexing
&lt;/Directory&gt;
&lt;Directory /web/docs/spec&gt;
    IndexOptions ScanHTMLTitles
&lt;/Directory&gt;
</pre>
        </blockquote>
        then only <code>ScanHTMLTitles</code> will be set for the
        /web/docs/spec directory.
      </dd>

      <dt>Apache 1.3.3 and later:</dt>

      <dd>
        <p>Apache 1.3.3 introduced some significant changes in the
        handling of <samp>IndexOptions</samp> directives. In
        particular,</p>

        <ul>
          <li>Multiple <samp>IndexOptions</samp> directives for a
          single directory are now merged together. The result of
          the example above will now be the equivalent of
          <code>IndexOptions&nbsp;FancyIndexing&nbsp;ScanHTMLTitles</code>.</li>

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

        <p>Whenever a '+' or '-' prefixed keyword is encountered,
        it is applied to the current <samp>IndexOptions</samp>
        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 so far. Consider the
        following example:</p>

        <blockquote>
          <code>IndexOptions +ScanHTMLTitles -IconsAreLinks
          FancyIndexing<br />
           IndexOptions +SuppressSize<br />
          </code>
        </blockquote>

        <p>The net effect is equivalent to
        <code>IndexOptions&nbsp;FancyIndexing&nbsp;+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>IndexOptions</code> for
        a particular directory, clearing the inherited settings,
        specify keywords without either '+' or '-' prefixes.</p>

    IndexOrderDefault is only available in Apache 1.3.4 and later. 

    <p>The <samp>IndexOrderDefault</samp> directive is used in
    combination with the <a
    href="#indexoptions:fancyindexing"><samp>FancyIndexing</samp></a>
    index option. By default, fancyindexed directory listings are
    displayed in ascending order by filename; the
    <samp>IndexOrderDefault</samp> allows you to change this
    initial display order.</p>

    <p><samp>IndexOrderDefault</samp> takes two arguments. The
    first must be either <samp>Ascending</samp> or
    <samp>Descending</samp>, indicating the direction of the sort.
    The second argument must be one of the keywords
    <samp>Name</samp>, <samp>Date</samp>, <samp>Size</samp>, or
    <samp>Description</samp>, and identifies the primary key. The
    secondary key is <em>always</em> the ascending filename.</p>

    <p>You can force a directory listing to only be displayed in a
    particular order by combining this directive with the <a
    href="#indexoptions:suppresscolumnsorting"><samp>SuppressColumnSorting</samp></a>
    index option; this will prevent the client from requesting the
    directory listing in a different order.</p>
