28 Conﬁguring Your Secure Web Server

DirectoryIndex The DirectoryIndex is the defaultpage servedby the

server when a user requests an index of a directory by specifying a

forward slash (/) at the end of the directory name.

For example, when a user requests the page

http://www.yourserver.com/thisdirectory/, they are go-

ing to get either the DirectoryIndex page if it exists, or a server-

generated directory listing. The default for DirectoryIndex is

index.html index.shtml index.cgi. The server will try to

ﬁnd any one of these three ﬁles, and will return the ﬁrst one it ﬁnds.

If it doesn’tﬁnd any of theseﬁles, the serverwill generateand return

an HTML listing of the subdirectories and ﬁles in the directory.

Alias TheAlias setting allowsdirectoriestobeoutsidetheDocumentRoot

directory and yet still accessible to the web server. Any URL end-

ing in the alias will automatically resolve to the alias’ path. By de-

fault, one alias is already set up. An icons directory can be ac-

cessed by the URL http://www.yourserver.com/icons/. The

icons directory, an alias, is actually /home/httpd/icons/, not

/home/httpd/html/icons/.

ScriptAlias TheScriptAlias settingdeﬁneswhereCGI scripts (or other

types of scripts) can be found. Generally, you don’t want to leave

CGI scripts within the DocumentRoot. If CGI scripts are in

DocumentRoot, they are visible as text documents. Even if you

don’t care if people can see (and then use) your CGI scripts, reveal-

ing how theywork createsopportunities for unscrupulous people to

exploit any securityholes inthe script,and maycreatea security risk

for your server. By default, the cgi-bin directory is a ScriptAlias

of/cgi-bin/,andisactuallylocatedin/home/httpd/cgi-bin/.

2.3.2 Other Directives in srm.conf

FancyIndexing FancyIndexing affects the appearance of server gen-

erated directory listings, by adding icons and descriptions, etc. If

FancyIndexing is turned on, clicking on the column headers will

sort the order of the display by that header. Another click on the

same header will switch from ascending to descending order and

back. FancyIndexing is set to on by default.
