Alias directive
Syntax: Alias URL-path file-path|directory-path
Context: server config, virtual host
Status: Base
Module: mod_alias

The Alias directive allows documents to be stored in the local filesystem other than under the DocumentRoot. URLs with a (%-decoded) path beginning with url-path will be mapped to local files beginning with directory-filename.

Example:

Alias /image /ftp/pub/image 
A request for http://myserver/image/foo.gif would cause the server to return the file /ftp/pub/image/foo.gif.

Note that if you include a trailing / on the url-path then the server will require a trailing / in order to expand the alias. That is, if you use Alias /icons/ /usr/local/apache/icons/ then the url /icons will not be aliased.

Note that you may need to specify additional <Directory> sections which cover the destination of aliases. Aliasing occurs before <Directory> sections are checked, so only the destination of aliases are affected. (Note however <Location> sections are run through once before aliases are performed, so they will apply.)
