Apache HTTP Server Version 1.3

Module mod_autoindex

Summary

• A file written by the user, typically called index.html. The DirectoryIndex directive sets the name of this file. This is controlled by mod_dir.
• Otherwise, a listing generated by the server. The other directives control the format of this listing. The AddIcon, AddIconByEncoding and AddIconByType 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 mod_autoindex.

If FancyIndexing is enabled, or the FancyIndexing keyword is present on the IndexOptions 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.

Note that when the display is sorted by "Size", it's the actual 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 "1K".

Directives

AddAlt

This sets the alternate text to display for a file, instead of an icon, for FancyIndexing. File is a file extension, partial filename, wild-card expression or full filename for files to describe. String is enclosed in double quotes ("). This alternate text is displayed if the client is image-incapable or has image loading disabled.

AddAltByEncoding

This sets the alternate text to display for a file, instead of an icon, for FancyIndexing. MIME-encoding is a valid content-encoding, such as x-compress. String is enclosed in double quotes ("). This alternate text is displayed if the client is image-incapable or has image loading disabled.

AddAltByType

This sets the alternate text to display for a file, instead of an icon, for FancyIndexing. MIME-type is a valid content-type, such as text/html. String is enclosed in double quotes ("). This alternate text is displayed if the client is image-incapable or has image loading disabled.

AddDescription

This sets the description to display for a file, for FancyIndexing. File is a file extension, partial filename, wild-card expression or full filename for files to describe. String is enclosed in double quotes ("). Example:

AddDescription "The planet Mars" /web/pics/mars.gif

AddIcon

This sets the icon to display next to a file ending in name for FancyIndexing. Icon is either a (%-escaped) relative URL to the icon, or of the format (alttext,url) where alttext is the text tag given for an icon for non-graphical browsers.

Name is either ^^DIRECTORY^^ for directories, ^^BLANKICON^^ for blank lines (to format the list correctly), a file extension, a wildcard expression, a partial filename or a complete filename. Examples:

AddIcon (IMG,/icons/image.xbm) .gif .jpg .xbm
AddIcon /icons/dir.xbm ^^DIRECTORY^^
AddIcon /icons/backup.xbm *~

AddIconByEncoding

This sets the icon to display next to files with mime-encoding for FancyIndexing. Icon is either a (%-escaped) relative URL to the icon, or of the format (alttext,url) where alttext is the text tag given for an icon for non-graphical browsers.

Mime-encoding is a wildcard expression matching required the content-encoding. Examples:

AddIconByEncoding /icons/compress.xbm x-compress

AddIconByType

This sets the icon to display next to files of type mime-type for FancyIndexing. Icon is either a (%-escaped) relative URL to the icon, or of the format (alttext,url) where alttext is the text tag given for an icon for non-graphical browsers.

Mime-type is a wildcard expression matching required the mime types. Examples:

AddIconByType (IMG,/icons/image.xbm) image/*

DefaultIcon

The DefaultIcon directive sets the icon to display for files when no specific icon is known, for FancyIndexing. Url is a (%-escaped) relative URL to the icon. Examples:

DefaultIcon /icon/unknown.xbm

FancyIndexing

The FancyIndexing directive sets the FancyIndexing option for a directory. Boolean can be on or off. The IndexOptions directive should be used in preference.

Note that the FancyIndexing and IndexOptions directives will override each other. You should use IndexOptions FancyIndexing in preference to the standalone FancyIndexing directive.

HeaderName

The HeaderName directive sets the name of the file that will be inserted at the top of the index listing. Filename is the name of the file to include, and is taken to be relative to the directory being indexed. The server first attempts to include filename.html as an HTML document, otherwise it will include filename as plain text. Example:

HeaderName HEADER

See also ReadmeName.

IndexIgnore

The IndexIgnore directive adds to the list of files to hide when listing a directory. File is a file extension, partial filename, wildcard expression or full filename for files to ignore. Multiple IndexIgnore directives add to the list, rather than the replacing the list of ignored files. By default, the list contains `.'. Example:

IndexIgnore README .htaccess *~

IndexOptions

The IndexOptions directive specifies the behavior of the directory indexing. Option can be one of

FancyIndexing

This turns on fancy indexing of directories.

Note that the FancyIndexing and IndexOptions directives will override each other. You should use IndexOptions FancyIndexing in preference to the standalone FancyIndexing directive.

IconHeight[=pixels] (Apache 1.3 and later)

Presence of this option, when used with IconWidth, will cause the server to include HEIGHT and WIDTH attributes in the IMG tag for the file icon. This allows browser to precalculate the page layout without having to wait until all the images have been loaded. If no value is given for the option, it defaults to the standard height of the icons supplied with the Apache software.

IconsAreLinks

This makes the icons part of the anchor for the filename, for fancy indexing.

IconWidth[=pixels] (Apache 1.3 and later)

Presence of this option, when used with IconHeight, will cause the server to include HEIGHT and WIDTH attributes in the IMG tag for the file icon. This allows browser to precalculate the page layout without having to wait until all the images have been loaded. If no value is given for the option, it defaults to the standard width of the icons supplied with the Apache software.

ScanHTMLTitles

This enables the extraction of the title from HTML documents for fancy indexing. If the file does not have a description given by AddDescription then httpd will read the document for the value of the TITLE tag. This is CPU and disk intensive.

SuppressColumnSorting

If specified, Apache will not make the column headings in a FancyIndexed directory listing into links for sorting. The default behaviour is for them to be links; selecting the column heading will sort the directory listing by the values in that column. Only available in Apache 1.3 and later.

SuppressDescription

This will suppress the file description in fancy indexing listings.

SuppressHTMLPreamble

If the directory actually contains a file specified by the HeaderName directive, the module usually includes the contents of the file after a standard HTML preamble (<HTML>, <HEAD>, et cetera). 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.

SuppressLastModified

This will suppress the display of the last modification date, in fancy indexing listings.

SuppressSize

This will suppress the file size in fancy indexing listings.

<Directory /web/docs>
IndexOptions FancyIndexing
</Directory>
<Directory /web/docs/spec>
IndexOptions ScanHTMLTitles
</Directory>

ReadmeName

The ReadmeName directive sets the name of the file that will be appended to the end of the index listing. Filename is the name of the file to include, and is taken to be relative to the directory being indexed. The server first attempts to include filename.html as an HTML document, otherwise it will include filename as plain text. Example:

ReadmeName README
