+<h3>Summary</h3>
+
+ <p>This module processes <code>.map</code> files, thereby
+ replacing the functionality of the <code>imagemap</code> CGI
+ program. Any directory or document type configured to use the
+ handler <code>imap-file</code> (using either
+ <code class="directive"><a href="../mod/mod_mime.html#addhandler">AddHandler</a></code> or
+ <code class="directive"><a href="../mod/core.html#sethandler">SetHandler</a></code>)
+ will be processed by this module.</p>
+
+ <p>The following directive will activate files ending with
+ <code>.map</code> as imagemap files:</p>
+
+ <pre class="prettyprint lang-config">AddHandler imap-file map</pre>
+
+
+ <p>Note that the following is still supported:</p>
+
+ <pre class="prettyprint lang-config">AddType application/x-httpd-imap map</pre>
+
+
+ <p>However, we are trying to phase out "magic MIME types" so we
+ are deprecating this method.</p>

+<h2><a name="features" id="features">New Features</a></h2>
+
+ <p>The imagemap module adds some new features that were not
+ possible with previously distributed imagemap programs.</p>
+
+ <ul>
+ <li>URL references relative to the Referer: information.</li>
+
+ <li>Default <code>&lt;base&gt;</code> assignment through a new map
+ directive <code>base</code>.</li>
+
+ <li>No need for <code>imagemap.conf</code> file.</li>
+
+ <li>Point references.</li>
+
+ <li>Configurable generation of imagemap menus.</li>
+ </ul>
+</div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
+<div class="section">
+<h2><a name="imapfile" id="imapfile">Imagemap File</a></h2>
+
+ <p>The lines in the imagemap files can have one of several
+ formats:</p>
+
+ <div class="example"><p><code>
+ directive value [<var>x</var>,<var>y</var> ...]<br />
+ directive value "<var>Menu text</var>" [<var>x</var>,<var>y</var>
+ ...]<br />
+ directive value <var>x</var>,<var>y</var> ... "<var>Menu text</var>"
+ </code></p></div>
+
+ <p>The directive is one of <code>base</code>,
+ <code>default</code>, <code>poly</code>, <code>circle</code>,
+ <code>rect</code>, or <code>point</code>. The value is an
+ absolute or relative URL, or one of the special values listed
+ below. The coordinates are <code><var>x</var>,<var>y</var></code>
+ pairs separated by whitespace. The quoted text is used as the text of
+ the link if a imagemap menu is generated. Lines beginning with '#' are
+ comments.</p>
+
+ <h3><a name="imapfile.directives" id="imapfile.directives">Imagemap File Directives</a></h3>
+ <p>There are six directives allowed in the imagemap file. The
+ directives can come in any order, but are processed in the
+ order they are found in the imagemap file.</p>
+
+ <dl>
+ <dt><code>base</code> Directive</dt>
+
+ <dd><p>Has the effect of <code>&lt;base href="<var>value</var>"&gt;
+ </code>. The non-absolute URLs of the map-file are taken relative
+ to this value. The <code>base</code> directive overrides
+ <code class="directive"><a href="#imapbase">ImapBase</a></code> as set in a
+ <code>.htaccess</code> file or in the server configuration files.
+ In the absence of an <code class="directive">ImapBase</code> configuration
+ directive, <code>base</code> defaults to
+ <code>http://server_name/</code>.</p>
+ <p><code>base_uri</code> is synonymous with <code>base</code>.
+ Note that a trailing slash on the URL is significant.</p></dd>
+
+ <dt><code>default</code> Directive</dt>
+
+ <dd>The action taken if the coordinates given do not fit any
+ of the <code>poly</code>, <code>circle</code> or
+ <code>rect</code> directives, and there are no
+ <code>point</code> directives. Defaults to <code>nocontent</code>
+ in the absence of an <code class="directive"><a href="#imapdefault">ImapDefault</a></code> configuration setting, causing a status
+ code of <code>204 No Content</code> to be returned. The client
+ should keep the same page displayed.</dd>
+
+ <dt><code>poly</code> Directive</dt>
+
+ <dd>Takes three to one-hundred points, and is obeyed if the
+ user selected coordinates fall within the polygon defined by
+ these points.</dd>
+
+ <dt><code>circle</code></dt>
+
+ <dd>Takes the center coordinates of a circle and a point on
+ the circle. Is obeyed if the user selected point is with the
+ circle.</dd>
+
+ <dt><code>rect</code> Directive</dt>
+
+ <dd>Takes the coordinates of two opposing corners of a
+ rectangle. Obeyed if the point selected is within this
+ rectangle.</dd>
+
+ <dt><code>point</code> Directive</dt>
+
+ <dd>Takes a single point. The point directive closest to the
+ user selected point is obeyed if no other directives are
+ satisfied. Note that <code>default</code> will not be
+ followed if a <code>point</code> directive is present and
+ valid coordinates are given.</dd>
+ </dl>
+
+
+ <h3><a name="imapfile.values" id="imapfile.values">Values</a></h3>
+
+ <p>The values for each of the directives can be any of the
+ following:</p>
+
+ <dl>
+ <dt>a URL</dt>
+
+ <dd><p>The URL can be relative or absolute URL. Relative URLs
+ can contain '..' syntax and will be resolved relative to the
+ <code>base</code> value.</p>
+ <p><code>base</code> itself will not be resolved according to the
+ current value. A statement <code>base mailto:</code> will
+ work properly, though.</p></dd>
+
+ <dt><code>map</code></dt>
+
+ <dd>Equivalent to the URL of the imagemap file itself. No
+ coordinates are sent with this, so a menu will be generated
+ unless <code class="directive"><a href="#imapmenu">ImapMenu</a></code> is set to
+ <code>none</code>.</dd>
+
+ <dt><code>menu</code></dt>
+ <dd>Synonymous with <code>map</code>.</dd>
+
+ <dt><code>referer</code></dt>
+
+ <dd>Equivalent to the URL of the referring document. Defaults
+ to <code>http://servername/</code> if no <code>Referer:</code>
+ header was present.</dd>
+
+ <dt><code>nocontent</code></dt>
+
+ <dd>Sends a status code of <code>204 No Content</code>,
+ telling the client to keep the same page displayed. Valid for
+ all but <code>base</code>.</dd>
+
+ <dt><code>error</code></dt>
+
+ <dd>Fails with a <code>500 Server Error</code>. Valid for all
+ but <code>base</code>, but sort of silly for anything but
+ <code>default</code>.</dd>
+ </dl>
+
+
+ <h3><a name="imapfile.coords" id="imapfile.coords">Coordinates</a></h3>
+
+ <dl>
+ <dt><code>0,0 200,200</code></dt>
+
+ <dd>A coordinate consists of an <var>x</var> and a <var>y</var>
+ value separated by a comma. The coordinates are separated
+ from each other by whitespace. To accommodate the way Lynx
+ handles imagemaps, should a user select the coordinate
+ <code>0,0</code>, it is as if no coordinate had been
+ selected.</dd>
+ </dl>
+
+
+
+ <h3><a name="imapfile.quotedtext" id="imapfile.quotedtext">Quoted Text</a></h3>
+
+ <dl>
+ <dt><code>"<var>Menu Text</var>"</code></dt>
+
+ <dd><p>After the value or after the coordinates, the line
+ optionally may contain text within double quotes. This string
+ is used as the text for the link if a menu is
+ generated:</p>
+
+ <div class="example"><p><code>
+ &lt;a href="http://example.com/"&gt;<var>Menu text</var>&lt;/a&gt;
+ </code></p></div>
+
+ <p>If no quoted text is present, the name of the link will be
+ used as the text:</p>
+
+ <div class="example"><p><code>
+ &lt;a href="http://example.com/"&gt;http://example.com&lt;/a&gt;
+ </code></p></div>
+
+ <p>If you want to use double quotes within this text, you have to
