Apache HTTP Server Version 1.3

Module mod_dir

This module is contained in the mod_dir.c file, and is compiled in by default. It provides for "trailing slash" redirects and serving directory index files.


The index of a directory can come from one of two sources: 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/.

    Syntax: DirectoryIndex local-url local-url ...
    Default: DirectoryIndex index.html
    Context: server config, virtual host, directory, .htaccess
    Override: Indexes
    Status: Base
    Module: mod_dir

    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.


    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.
