<H1 ALIGN="CENTER">Module mod_autoindex</H1>

This module is contained in the <CODE>mod_autoindex.c</CODE> file, and
is compiled in by default. It 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>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>.
</UL>
The two functions are separated so that you can completely remove
(or replace) automatic index generation should you want to.
<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 &quot;Size&quot;,
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 &quot;1K&quot;.
</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 bytes.
<blockquote>
As of Apache 1.3.10, the
<a href="#indexoptions:descriptionwidth">DescriptionWidth</a>
<samp>IndexOptions</samp> keyword allows you to adjust this width
to any arbitrary size.
</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.

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

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 <CODE>/web/HEADER</CODE>, if it exists.

<BLOCKQUOTE><STRONG>Apache versions after 1.3.6:</STRONG>

with a major content type of "<SAMP>text</SAMP>" (<EM>e.g.</EM>,

This means that <EM>filename</EM> may refer to a CGI script if the

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 normal files
<samp>Gamma</samp> and <samp>Alpha</samp>.

Presence of this option, when used with IconWidth, will cause the server
to include <SAMP>HEIGHT</SAMP> and <SAMP>WIDTH</SAMP> attributes in the

precalculate the page layout without having to wait until all the

defaults to the standard height of the icons supplied with the Apache
software.

The NameWidth keyword allows you to specify the width of the

This enables the extraction of the title from HTML documents for fancy

This will suppress the file description in fancy indexing listings.
<DT><A NAME="indexoptions:suppresshtmlpreamble">SuppressHTMLPreamble</A>
    (<EM>Apache 1.3 and later</EM>)
<DD>
<!--%plaintext &lt;?INDEX {\tt SuppressHTMLPreamble} index option&gt; -->
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 behaviour,
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.
<DT><A NAME="indexoptions:suppresslastmodified">SuppressLastModified</A>
<DD>
<!--%plaintext &lt;?INDEX {\tt SuppressLastModified} index option&gt; -->
This will suppress the display of the last modification date, in fancy
indexing listings.
<DT><A NAME="indexoptions:suppresssize">SuppressSize</A>
<DD>
<!--%plaintext &lt;?INDEX {\tt SuppressSize} index option&gt; -->
This will suppress the file size in fancy indexing listings.
</DL>
<P>
There are some noticeable differences in the behaviour 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:
<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.
</P>
</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>

<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.

The ReadmeName directive sets the name of the file that will be appended
to the end of the index listing. <EM>Filename</EM> is the name of the file
to include, and is taken to be relative to the location being indexed.

<BLOCKQUOTE>
<STRONG>The <EM>filename</EM> argument is treated as a stub filename
in Apache 1.3.6 and earlier, and as a relative URI in later versions.
Details of how it is handled may be found under the description of
the <A HREF="#headername">HeaderName</A> directive, which uses the
same mechanism and changed at the same time as ReadmeName.</STRONG>
