Module mod_alias

This module is contained in the mod_alias.c file, and is compiled in by default. It provides for mapping different parts of the host filesystem in the the document tree, and for URL redirection.

    • Alias

     Syntax: Alias url-path directory-filename
    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.

    See also ScriptAlias.

    Redirect

     Syntax: Redirect url-path url
    Context: server config, virtual host, directory, .htaccess
    Status: Base
    Module: mod_alias

    The Redirect directive maps an old URL into a new one. The new URL is returned to the client which attempts to fetch it again with the new address. Url-path a (%-decoded) path; any requests for documents beginning with this path will be returned a redirect error to a new (%-encoded) url beginning with url. Example:

    Redirect /service http://foo2.bar.com/service
    If the client requests http://myserver/service/foo.txt, it will be told to access http://foo2.bar.com/service/foo.txt instead.

    Note: Redirect directives take precedence over Alias and ScriptAlias directives, irrespective of their ordering in the configuration file.

    ScriptAlias

     Syntax: ScriptAlias url-path directory-filename
    Context: server config, virtual host
    Status: Base
    Module: mod_alias

    The ScriptAlias directive has the same behaviour as the Alias directive, except that in addition it marks the target directory as containing CGI scripts. URLs with a (%-decoded) path beginning with url-path will be mapped to scripts beginning with directory-filename. Example:

    ScriptAlias /cgi-bin/ /web/cgi-bin/
    A request for http://myserver/cgi-bin/foo would cause the server to run the script /web/cgi-bin/foo.
