This module provides for server-side imagemap processing.
Status: Base
Source File: mod_imap.c
Module Identifier: imap_module
Compatibility: Available in Apache 1.1 and later.
This module processes .map
files, thereby replacing the functionality of the imagemap
CGI program. Any directory or document type configured to use the handler imap-file
(using either AddHandler
or SetHandler
) will be processed by this module.
The following directive will activate files ending with .map
as imagemap files:
AddHandler imap-file map
Note that the following is still supported:
AddType application/x-httpd-imap map
However, we are trying to phase out "magic MIME types" so we are deprecating this method.
The imagemap module adds some new features that were not possible with previously distributed imagemap programs.
base
.imagemap.conf
file.The lines in the imagemap files can have one of several formats:
directive value [x,y ...]
directive value "Menu text" [x,y ...]
directive value x,y ... "Menu text"
The directive is one of base
, default
, poly
, circle
, rect
, or point
. The value is an absolute or relative URL, or one of the special values listed below. The coordinates are x,y
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.
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.
base
Directive<BASE HREF="value">
. The non-absolute URLs of the map-file are taken relative to this value. The base
directive overrides ImapBase as set in a .htaccess file or in the server configuration files. In the absence of an ImapBase configuration directive, base
defaults to http://server_name/
.base_uri
is synonymous with base
. Note that a trailing slash on the URL is significant.default
Directivepoly
, circle
or rect
directives, and there are no point
directives. Defaults to nocontent
in the absence of an ImapDefault configuration setting, causing a status code of 204 No Content
to be returned. The client should keep the same page displayed.poly

rect

will not be followed if a point
directive is present and valid coordinates are given.The values for each of the directives can any of the following:

ImapMenu none|formatted|semiformatted|unformatted
Context: server config, virtual host, directory, .htaccess
Override: Indexes
Module: mod_imap
Compatibility: ImapMenu is only available in Apache 1.1 and later.
The ImapMenu directive determines the action taken if an imagemap file is called without valid coordinates.
none
none
, no menu is generated, and the default
action is performed.formatted
formatted
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.semiformatted
semiformatted
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 formatted
menu.unformatted
ImapDefault error|nocontent|map|referer|URL
Context: server config, virtual host, directory, .htaccess
Override: Indexes
Module: mod_imap
Compatibility: ImapDefault is only available in Apache 1.1 and later.
The ImapDefault directive sets the default default
used in the imagemap files. Its value is overridden by a default
directive within the imagemap file. If not present, the default
action is nocontent
, which means that a 204 No Content
is sent to the client. In this case, the client should continue to display the original page.
ImapBase map|referer|URL
Context: server config, virtual host, directory, .htaccess
Override: Indexes
Module: mod_imap
Compatibility: ImapBase is only available in Apache 1.1 and later.
The ImapBase directive sets the default base
used in the imagemap files. Its value is overridden by a base
directive within the imagemap file. If not present, the base
defaults to http://servername/
.
