Chapter 6. Handling directories

FoldersFirst

List the subdirectories before the plain ﬁles.

SuppressHTMLPreamble

Instructs the web server not to create the HTML preamble but to rely on the

header ﬁle (identiﬁed by the HeaderName command) to provide it instead.

NameWidth=width (f)

Speciﬁes the width of the Name column. If the width is a number then it is that

many characters wide. If it is an asterisk then it is as wide as the longest name

(with a lower bound).

DescriptionWidth=width (f)

Speciﬁes the width of the Description column. If the width is a number then it

is that many characters wide. If it is an asterisk then it is as wide as the longest

description (with a lower bound).

IconWidth (f)

If icons are being used then this speciﬁes that the web server should include the

WIDTH attribute in the <IMG/> tag.

If it is used on its own then it inserts a width of 20 pixels. This is the width

of every icon shipped in the icons directory. Alternatively, it can be used as

IconWidth=N whereupon it will use N as the width. All icons must be of the

same width; Apache has no mechanism to analyse icons on the ﬂy.

IconHeight (f)

If icons are being used then this speciﬁes that the web server should include the

HEIGHT attribute in the <IMG/> tag.

If it is used on its own then it inserts a height of 22 pixels. This is the height

of every icon shipped in the icons directory. Alternatively, it can be used as

IconHeight=N whereupon it will use N as the height. All icons must be of the

same height; Apache has no mechanism to analyse icons on the ﬂy.

HTMLTable (f)

This instructs Apache to use an HTML table rather than a <PRE> block to present

the listing.

Using both modules

What happens if we run both modules? The answer is “it depends on what order we

load them in”. If we load autoindex_module and then dir_module the latter is never

used. The reason for this is that Apache runs though its modules in order looking

for one that can handle the request. If a directory query is received then, even if the

directory contains an index.html ﬁle, autoindex_module can handle it and does so.

If we load dir_module ﬁrst then the situation is far more useful. If there is

an index.html ﬁle then it is used. If there isn’t then the directory is indexed

automatically. But there’s a little more. If both are in play then the ScanHTMLTitles

option gives us a little more. If a subdirectory contains an index.html ﬁle then its

<TITLE> is used as a description for the directory in the parent directory’s automatic

index.
