This module is contained in the <CODE>mod_alias.c</CODE> file, and

is compiled in by default. It provides for mapping different parts of the

The Alias directive allows documents to be stored in the local filesystem
|
|
other than under the <A HREF="core.html#documentroot">DocumentRoot</A>.
|
|
URLs with a (%-decoded) path beginning with <EM>url-path</EM> will be
|
|
mapped to local files beginning with <EM>directory-filename</EM>.
|
|
<P>
|
|
Example:
|
|
</P>
|
|
<BLOCKQUOTE><CODE>Alias /image /ftp/pub/image</CODE></BLOCKQUOTE>
|
|
<P>
|
|
A request for http://myserver/image/foo.gif would cause the server to
|
|
return the file /ftp/pub/image/foo.gif.
|
|
</P>
|
|
<P>
|
|
Note that if you include a trailing / on the <EM>url-path</EM> then the
|
|
server will require a trailing / in order to expand the alias. That is,
|
|
if you use <CODE>Alias /icons/ /usr/local/apache/icons/</CODE> then
|
|
the url <CODE>/icons</CODE> will not be aliased.
|
|
</P>
|
|
<P>
|
|
Note that you may need to specify additional
|
|
<A HREF="core.html#directory"><CODE><Directory></CODE></A> sections
|
|
which cover the <EM>destination</EM> of aliases. Aliasing occurs
|
|
before <CODE><Directory></CODE> sections are checked, so only
|
|
the destination of aliases are affected. (Note however
|
|
<A HREF="core.html#location"><CODE><Location></CODE></A>
|
|
sections are run through once before aliases are performed, so they
|
|
will apply.)

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.
|
|
<EM>Url-path</EM> a (%-decoded) path; any requests for documents beginning with
|
|
this path will be returned a redirect error to a new (%-encoded) url
|
|
beginning with <EM>url</EM>.
|
|
</P>
|
|
<P>
|
|
Example:
|
|
</P>
|
|
<BLOCKQUOTE><CODE>Redirect /service
|
|
http://foo2.bar.com/service</CODE></BLOCKQUOTE>
|
|
<P>
|
|
If the client requests http://myserver/service/foo.txt, it will be told to
|
|
access http://foo2.bar.com/service/foo.txt instead.
|
|
</P>
|
|
<P>
|
|
<STRONG>Note:</STRONG> Redirect directives take precedence over Alias
|
|
and ScriptAlias
|
|
directives, irrespective of their ordering in the configuration file. Also,
|
|
<EM>Url-path</EM> must be an absolute path, not a relative path, even
|
|
when used with .htaccess files or inside of <Directory> sections.
|
|
</P>
|
|
<P>
|
|
If no <EM>status</EM> argument is given, the redirect will be
|
|
"temporary" (HTTP status 302). This indicates to the client that the
|
|
resources is has moved temporarily. The <EM>status</EM>
|
|
argument can be used to return other HTTP status codes:
|
|
<P>
|
|
<DL>
|
|
<DT>permanent
|
|
<DD>Returns a permanent redirect status (301) indicating that
|
|
the resource has moved permanently.
|
|
<DT>temp
|
|
<DD>Returns a temporary redirect status (302). This is the
|
|
default.
|
|
<DT>seeother
|
|
<DD>Returns a "See Other" status (303) indicating that
|
|
the resource has been replaced.
|
|
<DT>gone
|
|
<DD>Returns a "Gone" status (410) indicating that the resource
|
|
has been permanently removed. When this status is used the <EM>url</EM>
|
|
argument should be omitted.
|
|
</DL>
|
|
<P>
|
|
Other status codes can be returned by giving the numeric status code
|
|
as the value of <EM>status</EM>. If the status is between 300 and 399,
|
|
the <EM>url</EM> argument must be present, otherwise it must be
|
|
omitted. Note that the status must be known to the Apache code (see
|
|
the function <CODE>send_error_response</CODE> in http_protocol.c).
