# Module mod_dir

This module provides for "trailing slash" redirects and serving directory index files.

Status: Base
Source File: mod_dir.c
Module Identifier: dir_module

## 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/`.

## Directives

- DirectoryIndex

## DirectoryIndex directive

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.

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.
