    <p>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. <var>URL-path</var> a (%-decoded)
    path; any requests for documents beginning with this path will
    be returned a redirect error to a new (%-encoded) URL beginning
    with <var>URL</var>.</p>

    <div class="example"><h3>Example:</h3><p><code>
      Redirect /service http://foo2.bar.com/service
    </code></p></div>

    <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>

<div class="note"><h3>Note</h3> <p>Redirect directives take precedence over
Alias and ScriptAlias directives, irrespective of their ordering in
the configuration file. Also, <var>URL-path</var> must be a fully
qualified URL, not a relative path, even when used with .htaccess files or
inside of <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code>
sections.</p></div>

    <p>If no <var>status</var> argument is given, the redirect will
    be "temporary" (HTTP status 302). This indicates to the client
    that the resource has moved temporarily. The <var>status</var>
    argument can be used to return other HTTP status codes:</p>

    <dl>
      <dt>permanent</dt>

      <dd>Returns a permanent redirect status (301) indicating that
      the resource has moved permanently.</dd>

      <dt>temp</dt>

      <dd>Returns a temporary redirect status (302). This is the
      default.</dd>

      <dt>seeother</dt>

      <dd>Returns a "See Other" status (303) indicating that the
      resource has been replaced.</dd>

      <dt>gone</dt>

      <dd>Returns a "Gone" status (410) indicating that the
      resource has been permanently removed. When this status is
      used the <var>URL</var> argument should be omitted.</dd>
    </dl>

    <p>Other status codes can be returned by giving the numeric
    status code as the value of <var>status</var>. If the status is
    between 300 and 399, the <var>URL</var> 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).</p>

    <div class="example"><h3>Example:</h3><p><code>
      Redirect permanent /one http://example.com/two<br />
      Redirect 303 /three http://example.com/other
    </code></p></div>

    <p>This directive is equivalent to <code class="directive"><a href="#redirect">Redirect</a></code>, but makes use of standard
    regular expressions, instead of simple prefix matching. The
    supplied regular expression is matched against the URL-path, and
    if it matches, the server will substitute any parenthesized
    matches into the given string and use it as a filename. For
    example, to redirect all GIF files to like-named JPEG files on
    another server, one might use:</p>

    <div class="example"><p><code>
      RedirectMatch (.*)\.gif$ http://www.anotherserver.com$1.jpg
    </code></p></div>

    <p>The <code class="directive">ScriptAlias</code> directive has the same
    behavior as the <code class="directive"><a href="#alias">Alias</a></code>
    directive, except that in addition it marks the target directory
    as containing CGI scripts that will be processed by <code class="module"><a href="../mod/mod_cgi.html">mod_cgi</a></code>'s cgi-script handler. URLs with a
    (%-decoded) path beginning with <var>URL-path</var> will be mapped
    to scripts beginning with the second argument which is a full
    pathname in the local filesystem.</p>

    <div class="example"><h3>Example:</h3><p><code>
      ScriptAlias /cgi-bin/ /web/cgi-bin/
    </code></p></div>

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