Apache Module mod_dir
Summary
The index of a directory can come from one of two sources:
- 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. This is
provided by
mod_autoindex
.
The two functions are separated so that you can completely
remove (or replace) automatic index generation should you want
to.
A "trailing slash" redirect is issued when the server
receives a request for a URL
http://servername/foo/dirname
where
dirname
is a directory. Directories require a
trailing slash, so mod_dir
issues a redirect to
http://servername/foo/dirname/
.
The DirectoryIndex
directive sets the
list of resources to look for, when the client requests an index
of the directory by specifying a / at the end of the a directory
name. Local-url is the (%-encoded) URL of a document on
the server relative to the requested directory; it is usually the
name of a file in the directory. Several URLs may be given, in
which case the server will return the first one that it finds. If
none of the resources exist and the Indexes
option is
set, the server will generate its own listing of the
directory.
Example
DirectoryIndex index.html
then a request for http://myserver/docs/
would
return http://myserver/docs/index.html
if it
exists, or would list the directory if it did not.
Note that the documents do not need to be relative to the
directory;
DirectoryIndex index.html index.txt /cgi-bin/index.pl
would cause the CGI script /cgi-bin/index.pl
to be
executed if neither index.html
or index.txt
existed in a directory.
