AddAlt指令

AddAltprovides the alternate text to display for a file, instead of an icon, forFancyIndexing.Fileis a file extension, partial filename, wild-card expression or full filename for files to describe. IfStringcontains any whitespace, you have to enclose it in quotes ("或'). This alternate text is displayed if the client is image-incapable, has image loading disabled, or fails to retrieve the icon.

AddAltByEncoding指令

AddAltByEncodingprovides the alternate text to display for a file, instead of an icon, forFancyIndexing.MIME-encodingis a valid content-encoding, such asx-compress. IfStringcontains any whitespace, you have to enclose it in quotes ("或'). This alternate text is displayed if the client is image-incapable, has image loading disabled, or fails to retrieve the icon.

AddAltByType指令

AddAltByTypesets the alternate text to display for a file, instead of an icon, forFancyIndexing.MIME-typeis a valid content-type, such astext/html. IfStringcontains any whitespace, you have to enclose it in quotes ("或'). This alternate text is displayed if the client is image-incapable, has image loading disabled, or fails to retrieve the icon.

AddDescription指令

This sets the description to display for a file, forFancyIndexing.Fileis a file extension, partial filename, wild-card expression or full filename for files to describe.Stringis enclosed in double quotes (").

The typical, default description field is 23 bytes wide. 6 more bytes are added by theIndexOptions SuppressIconoption, 7 bytes are added by theIndexOptions SuppressSizeoption, and 19 bytes are added by theIndexOptions SuppressLastModifiedoption. Therefore, the widest default the description column is ever assigned is 55 bytes.

See the DescriptionWidthIndexOptionskeyword for details on overriding the size of this column, or allowing descriptions of unlimited length.

AddIcon指令

This sets the icon to display next to a file ending innameforFancyIndexing.Iconis either a (%-escaped) relative URL to the icon, or of the format(alttext,url)wherealttextis the text tag given for an icon for non-graphical browsers.

Nameis 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.

AddIconByTypeshould be used in preference toAddIcon, when possible.

AddIconByEncoding指令

This sets the icon to display next to files withFancyIndexing.Iconis either a (%-escaped) relative URL to the icon, or of the format(alttext,url)wherealttextis the text tag given for an icon for non-graphical browsers.

MIME-encodingis a wildcard expression matching required the content-encoding.

AddIconByType指令

This sets the icon to display next to files of typeMIME-typeforFancyIndexing.Iconis either a (%-escaped) relative URL to the icon, or of the format(alttext,url)wherealttextis the text tag given for an icon for non-graphical browsers.

MIME-typeis a wildcard expression matching required the mime types.

DefaultIcon指令

DefaultIcondirective sets the icon to display for files when no specific icon is known, forFancyIndexing.Url-pathis a (%-escaped) relative URL to the icon.

HeaderName指令

HeaderNamedirective sets the name of the file that will be inserted at the top of the index listing.Filenameis the name of the file to include.

If the file specified byHeaderNamecontains the beginnings of an HTML document (, , etc.) then you will probably want to setIndexOptions +SuppressHTMLPreamble, so that these tags are not repeated.

IndexIgnore指令

IndexIgnoredirective adds to the list of files to hide when listing a directory.Fileis a shell-style wildcard expression or full filename. Multiple IndexIgnore directives add to the list, rather than the replacing the list of ignored files. By default, the list contains.(the current directory).

IndexOptions指令

IndexOptionsdirective specifies the behavior of the directory indexing.Optioncan be one of

DescriptionWidth=[n| *]( Apache 2.0.23 and later)

The DescriptionWidthkeyword allows you to specify the width of the description column in characters.

-DescriptionWidth(or unset) allows mod_autoindexto calculate the best width.

DescriptionWidth=nfixes the column width to nbytes wide.

DescriptionWidth=*grows the column to the width necessary to accommodate the longest description string.

See the section onAddDescriptionfor dangers inherent in truncating descriptions.

FancyIndexing

This turns on fancy indexing of directories.

FoldersFirst( Apache 2.0.23 and later)

If this option is enabled, subdirectory listings will alwaysappear first, followed by normal files in the directory. The listing is basically broken into two components, the files and the subdirectories, and each is sorted separately and then displayed subdirectories-first. For instance, if the sort order is descending by name, and FoldersFirstis enabled, subdirectory Zedwill be listed before subdirectory Beta, which will be listed before normal files Gamma和 Alpha. This option only has an effect ifFancyIndexingis also enabled.

HTMLTable( Experimental, Apache 2.0.23 and later)

This experimental option with FancyIndexing constructs a simple table for the fancy directory listing. Note this will confuse older browsers. It is particularly necessary if file names or description text will alternate between left-to-right and right-to-left reading order, as can happen on WinNT or other utf-8 enabled platforms.

IconsAreLinks

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

IconHeight[=pixels]

Presence of this option, when used with IconWidth, will cause the server to include height和 widthattributes in the imgtag 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.

IconWidth[=pixels]

Presence of this option, when used with IconHeight, will cause the server to include height和 widthattributes in the imgtag 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.

IgnoreCase

If this option is enabled, names are sorted in a case-insensitive manner. For instance, if the sort order is ascending by name, and IgnoreCase is enabled, file Zeta will be listed after file alfa (Note: file GAMMA will always be listed before file gamma).

IgnoreClient

This option causes mod_autoindexto ignore all query variables from the client, including sort order (implies SuppressColumnSorting.)

NameWidth=[n| *]

The NameWidthkeyword allows you to specify the width of the filename column in bytes.

-NameWidth(or unset) allows mod_autoindexto calculate the best width.

NameWidth=nfixes the column width to nbytes wide.

NameWidth=*grows the column to the necessary width.

ScanHTMLTitles

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

ShowForbidden

If specified, Apache will show files normally hidden because the subrequest returned HTTP_UNAUTHORIZED or HTTP_FORBIDDEN

SuppressColumnSorting

If specified, Apache will not make the column headings in a FancyIndexed directory listing into links for sorting. The default behavior is for them to be links; selecting the column heading will sort the directory listing by the values in that column. Prior to Apache 2.0.23, this also disabled parsing the Query Arguments for the sort string.That behavior is now controlled by IndexOptions IgnoreClient in Apache 2.0.23.

SuppressDescription

This will suppress the file description in fancy indexing listings. By default, no file descriptions are defined, and so the use of this option will regain 23 characters of screen space to use for something else. See AddDescriptionfor information about setting the file description. See also the DescriptionWidthindex option to limit the size of the description column.

SuppressHTMLPreamble

If the directory actually contains a file specified by the HeaderNamedirective, the module usually includes the contents of the file after a standard HTML preamble ( , , et cetera). The SuppressHTMLPreambleoption 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.

SuppressIcon( Apache 2.0.23 and later)

This will suppress the icon in fancy indexing listings. Combining both SuppressIcon和 SuppressRulesyields proper HTML 3.2 output, which by the final specification prohibits img和 hrelements from the preblock (used to format FancyIndexed listings.)

SuppressLastModified

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

SuppressRules( Apache 2.0.23 and later)

This will suppress the horizontal rule lines ( hrelements) in directory listings. Combining both SuppressIcon和 SuppressRulesyields proper HTML 3.2 output, which by the final specification prohibits img和 hrelements from the preblock (used to format FancyIndexed listings.)

SuppressSize

This will suppress the file size in fancy indexing listings.

TrackModified( Apache 2.0.23 and later)

This returns the Last-Modified and ETag values for the listed directory in the HTTP header. It is only valid if the operating system and file system return appropriate stat() results. Some Unix systems do so, as do OS2's JFS and Win32's NTFS volumes. OS2 and Win32 FAT volumes, for example, do not. Once this feature is enabled, the client or proxy can track changes to the list of files when they perform a HEADrequest. Note some operating systems correctly track new and removed files, but do not track changes for sizes or dates of the files within the directory. Changes to the size or date stamp of an existing file will not update the Last-Modified header on all Unix platforms.If this is a concern, leave this option disabled.

VersionSort( Apache 2.0a3 and later)

The VersionSortkeyword causes files containing version numbers to sort in a natural way. Strings are sorted as usual, except that substrings of digits in the name and description are compared according to their numeric value.

示例：

foo-1.7
foo-1.7.2
foo-1.7.12
foo-1.8.2
foo-1.8.2a
foo-1.12

If the number starts with a zero, then it is considered to be a fraction:

foo-1.001
foo-1.002
foo-1.030
foo-1.04

XHTML( Apache 2.0.49 and later)

The XHTMLkeyword forces mod_autoindexto emit XHTML 1.0 code instead of HTML 3.2.

Incremental IndexOptions

Apache 1.3.3 introduced some significant changes in the handling ofIndexOptionsdirectives. In particular:

• MultipleIndexOptionsdirectives for a single directory are now merged together. The result of:

  IndexOptions HTMLTable
IndexOptions SuppressColumnsorting

  will be the equivalent of

  IndexOptions HTMLTable SuppressColumnsorting

• The addition of the incremental syntax (i.e., prefixing keywords with+或-).

Whenever a '+' or '-' prefixed keyword is encountered, it is applied to the currentIndexOptionssettings (which may have been inherited from an upper-level directory). However, whenever an unprefixed keyword is processed, it clears all inherited options and any incremental settings encountered so far. Consider the following example:

IndexOptions +ScanHTMLTitles -IconsAreLinks FancyIndexing
IndexOptions +SuppressSize

The net effect is equivalent toIndexOptions FancyIndexing +SuppressSize, because the unprefixedFancyIndexingdiscarded the incremental keywords before it, but allowed them to start accumulating again afterward.

To unconditionally set theIndexOptionsfor a particular directory, clearing the inherited settings, specify keywords without any+或-prefixes.

IndexOrderDefault指令

IndexOrderDefaultdirective is used in combination with theFancyIndexingindex option. By default, fancyindexed directory listings are displayed in ascending order by filename; theIndexOrderDefaultallows you to change this initial display order.

IndexOrderDefaulttakes two arguments. The first must be eitherAscending或Descending, indicating the direction of the sort. The second argument must be one of the keywordsName,Date,Size, orDescription, and identifies the primary key. The secondary key isalwaysthe ascending filename.

You can force a directory listing to only be displayed in a particular order by combining this directive with theSuppressColumnSortingindex option; this will prevent the client from requesting the directory listing in a different order.

IndexStyleSheet指令

IndexStyleSheetdirective sets the name of the file that will be used as the CSS for the index listing.

ReadmeName指令

ReadmeNamedirective sets the name of the file that will be appended to the end of the index listing.Filenameis the name of the file to include, and is taken to be relative to the location being indexed. IfFilenamebegins with a slash, it will be taken to be relative to theDocumentRoot.

See alsoHeaderName, where this behavior is described in greater detail.
