10.3 IndexOptions The arguments to IndexOptions are as follows You should demonstrate each of these options so that the students can see what happens Note that for the ones that are Apache 2.0 specific, you will need to switch over to that configuration file, which will confuse the students that are following along. Encourage them to try each of these options as well. • None IndexOptions None causes a directory listing to be generated as a simple bullet-list of items with links to the file itself. • FancyIndexing This option is necessary for all following ones. That is, turning on FancyIndexing enables the use of all other index options. • DescriptionWidth • NameWidth Allows you to set the number of characters available for the description of the file or directory. Or the name of the file or directory. Respectively. • FoldersFirst Display the folders first in the listing, as people are used to seeing in various file managers. • HTMLTable (Apache 2.0) The default directory index listing is not HTML-complient, because it contains formatting and image tags inside pre tags. Some people get uptight about stuff like this. Displaying the listing as an HTML table gets around this, and produces HTML-complient listings. The purpose of the pre tags is to get the columns to line up, and pre-dates the availablilty of HTML tables. This feature is only available in Apache 2.0, because nobody has cared to back-port it to 1.3. • IconHeight, IconWidth Adds width= and height= tags to the HTML img tag to facilitate rapid page rendering. • IconsAreLinks The icons are not usually links to the file. This option makes them such. However, it also put the large blue border around each icon, which is irritating. • IgnoreClient • SuppressColumnSorting These two options should be considered together, as it is easy to get confused which is which, and why you need both of them. IgnoreClient ignores arguments passed in the URL for reordering the entries by column. However, the links are still at the top of each column to re-order the entries. SuppressColumnSorting removes the links at the top of each column, but still will honor the arguments in a URL to reorder, if the user types it in, or if it is linked to explicitly. So, it really only makes sense to use both of these options, or neither. I’m not sure why anyone would feel the need to do this, but perhaps a particular ordering is required for some pages. 58
• ScanHTMLTitles For HTML files, the file is opened and the value of the title tag is placed into the description field for the directory listing. Note that this is a HUGE performance hit. • SuppressHTMLPreamble Useful when using HeaderName. The HTML preamble (the head and body tags, as well as the ”Index of /foo” text) are ommitted, and you can replace them with the contents of the HeaderName file instead. Otherwise, any head or body tags that you put in the HeaderName file will probably be ignored by the client. • SuppressDescription • SuppressIcon • SuppressLastModified • SuppressSize Don’t display the column in question • SuppressRules • TrackModified Send a Last-Modified header which reflects the last time a file in this directory was modified. Otherwise, the Last-Modified header will always be the time of the request, because the resulting document is being generated fresh each time. • VersionSort 1.1, 1.2, 1.10 rather than 1.1, 1.10, 1.2 Other directives are: • AddIcon • AddIconByType • AddIconByEncoding • DefaultIcon • AddDescription Note that this directive is a substring match, not a literal file name, or even a file extension. This can cause confusion if you happen to have multiple files with similar names, and wish to give them different descriptions. Thus: AddDescription "The Foo page" foo.html AddDescription "Other foo stuff" foo Will not work as desired, whereas: AddDescription "Other foo stuff" foo AddDescription "The Foo page" foo.html will.
