19.21. mod_imap

The mod_imap module provides support for .map files and imagemaps. Imagemaps allow a server to respond to clicks in various "hot zones" of an image, without creating an explicit link to redirect the client.

ImapBase

ImapBase map|referer|url

[server config, or within <VirtualHost> or <Directory>, or .htaccess]

Specifies the default base for imagemap files, if there is no base directive in the imagemap file itself. A URL can be specified, or one of the following options can be used:


map

Uses the URL of the imagemap file.


referer

Uses the referring document or the ServerRoot if a Referer header is not specified.

(Apache 1.1 or later)

ImapDefault

ImapDefault error|nocontent|map|referer|URL

[server config, or within <VirtualHost> or <Directory>, or .htaccess]

Specifies the default action for imagemap files, if there is no default directive in the imagemap file itself. A URL can be specified, or one of the following options can be used:


error

Fails with a server response code of 500 (see Chapter 17).


nocontent

Sends a server response code of 204, telling the client to keep the same page displayed (see Chapter 17).


map

Uses the URL of the imagemap file.


referer

Uses the referring document, or the server root if a Referer header is not specified.

(Apache 1.1 or later)

ImapMenu

ImapMenu none|formatted|semiformatted|unformatted

[server config, or within <VirtualHost> or <Directory>, or .htaccess]

Under Apache, if an imagemap is called without valid coordinates, the server can return a menu of the items in the imagemap file. The ImapMenu directive configures that menu. Options are:


none

No menu is created. The action specified with ImapDefault is taken.


formatted

A formatted menu is generated, with a listing of the possible links.


semiformatted

A menu with comments from the imagemap file and simple breaks is generated, with a listing of the possible links.


unformatted

A menu with the text of the imagemap file, unformatted. Useful if map files are written as HTML.

(Apache 1.1 or later)
