Apache HTTP Server Version 2.0
Apache HTTP Server Version 2.0
| Description: | Provides for "trailing slash" redirects and serving directory index files |
|---|---|
| Status: | Base |
| Module Identifier: | dir_module |
| Source File: | mod_dir.c |
The index of a directory can come from one of two sources:
index.html. The DirectoryIndex directive sets the name of this file. This is controlled by mod_dir.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/.
| Description: | List of resources to look for when the client requests a directory |
|---|---|
| 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 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.
| Description: | Toggle trailing slash redirects on or off |
|---|---|
| Syntax: | DirectorySlash On|Off |
| Default: | DirectorySlash On |
| Context: | server config, virtual host, directory, .htaccess |
| Override: | Indexes |
| Status: | Base |
| Module: | mod_dir |
| Compatibility: | Available in version 2.0.51 and later |
The DirectorySlash directive determines, whether mod_dir should fixup URLs pointing to a directory or not.
Typically if a user requests a resource without a trailing slash, which points to a directory, mod_dir redirects him to the same ressource, but with trailing slash for some good reasons:
mod_autoindex works correctly. Since it doesn't emit the path in the link, it would point to the wrong path.DirectoryIndex will be evaluated only for directories requested with trailing slash.Well, if you don't want this effect and the reasons above don't apply to you, you can turn off the redirect with:
# see security warning below!
<Location /some/path>
DirectorySlash Off
SetHandler some-handler
</Location>
Turning off the trailing slash redirect may result in an information disclosure. Consider a situation where mod_autoindex is active (Options +Indexes) and DirectoryIndex is set to a valid resource (say, index.html) and there's no other special handler defined for that URL. In this case a request with a trailing slash would show the index.html file. But a request without trailing slash would list the directory contents.
