Description:

This module provides for mapping different parts of the host
filesystem in the document tree, and for URL redirection. The
directives contained in this module allow for manipulation and control
of URLs as requests arrive at the server. The Alias and ScriptAlias
directives are used to map between URLs and filesystem paths. This
allows for content which is not directly under the DocumentRoot to be
served as part of the web document tree. The ScriptAlias directive has
the additional effect of marking the target directory as containing
only CGI scripts.

The Redirect directives are used to instruct clients to make a new
request with a different URL. They are often used when a resource has
moved to a new location.

A more powerful and flexible set of directives for manipulating URLs
is contained in the mod_rewrite module.
