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

 This module is contained in the <CODE>mod_imap.c</CODE> file, and is
 compiled in by default. It provides for <CODE>.map</CODE> files,
 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><A
 HREF="mod_mime.html#addhandler">AddHandler</A> </CODE> or <CODE><A
 HREF="mod_mime.html#sethandler">SetHandler</A></CODE>) will be
 processed by this module.

 <H2>Summary</H2>

 This module is in the default Apache distribution. The following directive will
 activate files ending with <CODE>.map</CODE> as imagemap files:

 <BLOCKQUOTE><CODE>AddHandler imap-file map</CODE></BLOCKQUOTE>

 Note that the following is still supported:

  <BLOCKQUOTE><CODE>AddType application/x-httpd-imap map</CODE></BLOCKQUOTE>

 However, we are trying to phase out "magic MIME types" so we are deprecating
 this method.

 <H2>New Features</H2>
 The imagemap module adds some new features that were not
 possible with previously distributed imagemap programs.<P>

 The ImapMenu directive determines the action taken if an imagemap file
 is called without valid coordinates.
 <DL>
   <DT><CODE>none</CODE>
   <DD>If ImapMenu is
        <CODE>none</CODE>, no menu is generated, and the <CODE>default</CODE>
        action is performed.
   <DT><CODE>formatted</CODE>
   <DD>A <CODE>formatted</CODE> menu is the simplest menu.  Comments
        in the imagemap file are ignored.  A level one header is
        printed, then an hrule, then the links each on a separate line.
        The menu has a consistent, plain look close to that of
        a directory listing.
   <DT><CODE>semiformatted</CODE>
   <DD>In the <CODE>semiformatted</CODE> menu, comments are printed
        where they occur in the imagemap file.  Blank lines are turned
        into HTML breaks.  No header or hrule is printed, but otherwise
        the menu is the same as a <CODE>formatted</CODE> menu.
   <DT><CODE>unformatted</CODE>
   <DD>Comments are printed, blank lines are ignored.  Nothing is
        printed that does not appear in the imagemap file.  All breaks
        and headers must be included as comments in the imagemap file.
        This gives you the most flexibility over the appearance of your
        menus, but requires you to treat your map files as HTML instead
        of plaintext.

 The ImapBase directive sets the default <CODE>base</CODE> used in
 the imagemap files.  It's value is overridden by a <CODE>base</CODE>
 directive within the imagemap file.  If not present, the
 <CODE>base</CODE> defaults to <CODE>http://servername/</CODE>.

 <HR>
 <P>

 <H2>Imagemap File</H2>
 The lines in the imagemap files can have one of several formats:
 <BLOCKQUOTE>
 <CODE>directive value [x,y ...]</CODE><BR>
 <CODE>directive value "Menu text" [x,y ...]</CODE><BR>
 <CODE>directive value x,y ... "Menu text"</CODE><BR>
 </BLOCKQUOTE>
 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>x,y</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.

 <H3>Imagemap File Directives</H3>
 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.
 <DL>
 <DT><CODE>base</CODE> Directive
 <DD>Has the effect of <CODE>&lt;BASE HREF="value"&gt;</CODE>.  The
      non-absolute URLs of the map-file are taken relative to this value.
      The <CODE>base</CODE> directive overrides ImapBase as set in a
      .htaccess file or in the server configuration files.  In the absence
      of an ImapBase configuration directive, <CODE>base</CODE> defaults to
      <CODE>http://server_name/</CODE>. <BR>
      <CODE>base_uri</CODE> is synonymous with <CODE>base</CODE>.  Note that
      a trailing slash on the URL is significant.
 <P>
 <DT><CODE>default</CODE> Directive
 <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 ImapDefault
      configuration setting, causing a status code of <CODE>204 No
      Content</CODE> to be returned.  The client should keep the same
      page displayed.
 <P>
 <DT><CODE>poly</CODE> Directive
 <DD>Takes three to one-hundred points, and is obeyed if the user selected
      coordinates fall within the polygon defined by these points.
 <P>
 <DT><CODE>circle</CODE>
 <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.
 <P>
 <DT><CODE>rect</CODE> Directive
 <DD>Takes the coordinates of two opposing corners of a rectangle.  Obeyed
      if the point selected is within this rectangle.
 <P>
 <DT><CODE>point</CODE> Directive
 <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.
 </DL>


 <H3>Values</H3>
 The values for each of the directives can any of the following:
 <DL>
   <DT>a URL
   <DD>The URL can be relative or absolute URL.  Relative URLs can
        contain '..' syntax and will be resolved relative to the
        <CODE>base</CODE> value. <BR>
        <CODE>base</CODE> itself will not resolved according to the current
        value. A statement <CODE>base mailto:</CODE> will work properly, though.
 <P>
   <DT><CODE>map</CODE>
   <DD>Equivalent to the URL of the imagemap file itself.  No
        coordinates are sent with this, so a menu will be generated
        unless ImapMenu is set to 'none'.
 <P>
   <DT><CODE>menu</CODE>
   <DD>Synonymous with <CODE>map</CODE>.
 <P>
   <DT><CODE>referer</CODE>
   <DD>Equivalent to the URL of the referring document.
        Defaults to <CODE>http://servername/</CODE> if no Referer:
        header was present.
 <P>
   <DT><CODE>nocontent</CODE>
   <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>.
 <P>
   <DT><CODE>error</CODE>
   <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>.
 </DL>

 <H3>Coordinates</H3>
 <DL>
   <DT><CODE>0,0 200,200</CODE>
   <DD>A coordinate consists of an <TT>x</TT> and a <TT>y</TT> 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.
 </DL>

 <H3>Quoted Text</H3>
 <DL>
   <DT><CODE>"Menu Text"</CODE>
   <DD>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:<BR>
      <CODE>&lt;a HREF="http://foo.com/"&gt;Menu text&lt;/a&gt;</CODE><BR>
        If no quoted text is present, the name of the link will be used
        as the text:<BR>
      <CODE>&lt;a HREF="http://foo.com/"&gt;http://foo.com&lt;/a&gt;</CODE><BR>
        It is impossible to escape double quotes within this text.
 </DL>

	<DD>A coordinate consists of an <TT>x</TT> and a <TT>y</TT> 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.

	<DT><CODE>"Menu Text"</CODE>
	<DD>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:<BR>
	<CODE><a HREF="http://foo.com/">Menu text</a></CODE><BR>
	If no quoted text is present, the name of the link will be used
	as the text:<BR>
	<CODE><a HREF="http://foo.com/">http://foo.com</a></CODE><BR>
	It is impossible to escape double quotes within this text.
