<h3>Summary</h3>

    <p>The directives contained in this module allow for manipulation
    and control of URLs as requests arrive at the server. The
    <code class="directive"><a href="#alias">Alias</a></code> and <code class="directive"><a href="#scriptalias">ScriptAlias</a></code> directives are used to
    map between URLs and filesystem paths.  This allows for content
    which is not directly under the <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> served as part of the web
    document tree. The <code class="directive"><a href="#scriptalias">ScriptAlias</a></code> directive has the
    additional effect of marking the target directory as containing
    only CGI scripts.</p>

    <p>The <code class="directive"><a href="#redirect">Redirect</a></code>
    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.</p>

    <p><code class="module"><a href="../mod/mod_alias.html">mod_alias</a></code> is designed to handle simple URL
    manipulation tasks.  For more complicated tasks such as
    manipulating the query string, use the tools provided by
    <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>.</p>

<h2><a name="order" id="order">Order of Processing</a></h2>

    <p>Aliases and Redirects occurring in different contexts are processed
    like other directives according to standard <a href="../sections.html#mergin">merging rules</a>.  But when multiple
    Aliases or Redirects occur in the same context (for example, in the
    same <code class="directive"><a href="../mod/core.html#virtualhost">&lt;VirtualHost&gt;</a></code>
    section) they are processed in a particular order.</p>

    <p>First, all Redirects are processed before Aliases are processed,
    and therefore a request that matches a <code class="directive"><a href="#redirect">Redirect</a></code> or <code class="directive"><a href="#redirectmatch">RedirectMatch</a></code> will never have Aliases
    applied.  Second, the Aliases and Redirects are processed in the order
    they appear in the configuration files, with the first match taking
    precedence.</p>

    <p>For this reason, when two or more of these directives apply to the
    same sub-path, you must list the most specific path first in order for
    all the directives to have an effect.  For example, the following
    configuration will work as expected:</p>

    <div class="example"><p><code>
    Alias /foo/bar /baz<br />
    Alias /foo /gaq
    </code></p></div>

    <p>But if the above two directives were reversed in order, the
    <code>/foo</code> <code class="directive"><a href="#alias">Alias</a></code>
    would always match before the <code>/foo/bar</code> <code class="directive"><a href="#alias">Alias</a></code>, so the latter directive would be
    ignored.</p>

    <p>The <code class="directive">Alias</code> directive allows documents to
    be stored in the local filesystem other than under the
    <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code>. URLs with a
    (%-decoded) path beginning with <var>URL-path</var> will be mapped
    to local files beginning with <var>directory-path</var>.  The
    <var>URL-path</var> is case-sensitive, even on case-insensitive
    file systems.</p>

    <div class="example"><h3>Example:</h3><p><code>
      Alias /image /ftp/pub/image
    </code></p></div>

    <p>A request for <code>http://example.com/image/foo.gif</code> would cause
    the server to return the file <code>/ftp/pub/image/foo.gif</code>.  Only
    complete path segments are matched, so the above alias would not match a
    request for <code>http://example.com/imagefoo.gif</code>.  For more complex
    matching using regular expressions, see the <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> directive.</p>

    <p>Note that if you include a trailing / on the
    <var>URL-path</var> then the server will require a trailing / in
    order to expand the alias. That is, if you use</p>

    <div class="example"><p><code>
        Alias /icons/ /usr/local/apache/icons/
    </code></p></div>

    <p>then the URL <code>/icons</code> will not be aliased, as it lacks
    that trailing /. Likewise, if you omit the slash on the
    <var>URL-path</var> then you must also omit it from the
    <var>file-path</var>.</p>

    <p>Note that you may need to specify additional <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> sections which
    cover the <em>destination</em> of aliases.  Aliasing occurs before
    <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code> sections
    are checked, so only the destination of aliases are affected.
    (Note however <code class="directive"><a href="../mod/core.html#location">&lt;Location&gt;</a></code>
    sections are run through once before aliases are performed, so
    they will apply.)</p>

    <p>In particular, if you are creating an <code>Alias</code> to a
    directory outside of your <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code>, you may need to explicitly
    permit access to the target directory.</p>

    <div class="example"><h3>Example:</h3><p><code>
        Alias /image /ftp/pub/image<br />
        &lt;Directory /ftp/pub/image&gt;<br />
        <span class="indent">
            Order allow,deny<br />
            Allow from all<br />
        </span>
        &lt;/Directory&gt;
    </code></p></div>

    <p>Any number of slashes in the <var>URL-path</var> parameter
    matches any number of slashes in the requested URL-path.</p>

    <p>This directive is equivalent to <code class="directive"><a href="#alias">Alias</a></code>, but makes use of
    <a class="glossarylink" href="../glossary.html#regex" title="see glossary">regular expressions</a>,
    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 activate the <code>/icons</code> directory, one might
    use:</p>

    <div class="example"><p><code>
      AliasMatch ^/icons(.*) /usr/local/apache/icons$1
    </code></p></div>

    <p>The full range of <a class="glossarylink" href="../glossary.html#regex" title="see glossary">regular expression</a>
    power is available.  For example,
    it is possible to construct an alias with case-insensitive
    matching of the URL-path:</p>

    <div class="example"><p><code>
      AliasMatch (?i)^/image(.*) /ftp/pub/image$1
    </code></p></div>

    <p>One subtle difference
    between <code class="directive"><a href="#alias">Alias</a></code>
    and <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> is
    that <code class="directive"><a href="#alias">Alias</a></code> will
    automatically copy any additional part of the URI, past the part
    that matched, onto the end of the file path on the right side,
    while <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> will
    not.  This means that in almost all cases, you will want the
    regular expression to match the entire request URI from beginning
    to end, and to use substitution on the right side.</p>

    <p>In other words, just changing 
    <code class="directive"><a href="#alias">Alias</a></code> to
    <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> will not
    have the same effect.  At a minimum, you need to
    add <code>^</code> to the beginning of the regular expression
    and add <code>(.*)$</code> to the end, and add <code>$1</code> to
    the end of the replacement.</p>

    <p>For example, suppose you want to replace this with AliasMatch:</p>

    <div class="example"><p><code>
      Alias /image/ /ftp/pub/image/
    </code></p></div>

    <p>This is NOT equivalent - don't do this!  This will send all
    requests that have /image/ anywhere in them to /ftp/pub/image/:</p>

    <div class="example"><p><code>
      AliasMatch /image/ /ftp/pub/image/
    </code></p></div>

    <p>This is what you need to get the same effect:</p>

    <div class="example"><p><code>
      AliasMatch ^/image/(.*)$ /ftp/pub/image/$1
    </code></p></div>

    <p>Of course, there's no point in
    using <code class="directive"><a href="#aliasmatch">AliasMatch</a></code>
    where <code class="directive"><a href="#alias">Alias</a></code> would
    work.  <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> lets
    you do more complicated things.  For example, you could
    serve different kinds of files from different directories:</p>

    <div class="example"><p><code>
      AliasMatch ^/image/(.*)\.jpg$ /files/jpg.images/$1.jpg<br />
      AliasMatch ^/image/(.*)\.gif$ /files/gif.images/$1.gif
    </code></p></div>

    <p>Multiple leading slashes in the requested URL are discarded
       by the server before directives from this module compares
       against the requested URL-path.
    </p>

</table>
    <p>The Redirect directive maps an old URL into a new one by asking
    the client to refetch the resource at the new location.</p>

    <p>The old <em>URL-path</em> is a case-sensitive (%-decoded) path
    beginning with a slash.  A relative path is not allowed.  The new
    <em>URL</em> should be an absolute URL beginning with a scheme and
    hostname.  In Apache HTTP Server 2.2.6 and later, a URL-path beginning 
    with a slash may also be used, in which case the scheme and hostname 
    of the current server will be added.</p>

    <p>Then any request beginning with <em>URL-path</em> will return a
    redirect request to the client at the location of the target
    <em>URL</em>.  Additional path information beyond the matched
    <em>URL-path</em> will be appended to the target URL.</p>

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

    <p>If the client requests <code>http://example.com/service/foo.txt</code>,
    it will be told to access
    <code>http://foo2.example.com/service/foo.txt</code>
    instead.  Only complete path segments are matched, so the above
    example would not match a request for
    <code>http://example.com/servicefoo.txt</code>.  For more complex matching
    using regular expressions, see the <code class="directive"><a href="#redirectmatch">RedirectMatch</a></code> directive.</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.</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

    <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 case-sensitive
    (%-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://example.com/cgi-bin/foo</code> would cause the
    server to run the script <code>/web/cgi-bin/foo</code>.  This configuration
    is essentially equivalent to:</p>
    <div class="example"><p><code>
      Alias /cgi-bin/ /web/cgi-bin/<br />
      &lt;Location /cgi-bin &gt;<br />
      <span class="indent">
      SetHandler cgi-script<br />
      Options +ExecCGI<br />
      </span>
      &lt;/Location&gt;
    </code></p></div>

    <div class="warning">It is safer to avoid placing CGI scripts under the
    <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> in order to
    avoid accidentally revealing their source code if the
    configuration is ever changed.  The
    <code class="directive">ScriptAlias</code> makes this easy by mapping a
    URL and designating CGI scripts at the same time.  If you do
    choose to place your CGI scripts in a directory already
    accessible from the web, do not use
    <code class="directive">ScriptAlias</code>.  Instead, use <code class="directive"><a href="../mod/core.html#directory">&lt;Directory&gt;</a></code>, <code class="directive"><a href="../mod/core.html#sethandler">SetHandler</a></code>, and <code class="directive"><a href="../mod/core.html#options">Options</a></code> as in:
    <div class="example"><p><code>
      &lt;Directory /usr/local/apache2/htdocs/cgi-bin &gt;<br />
      <span class="indent">
      SetHandler cgi-script<br />
      Options ExecCGI<br />
      </span>
      &lt;/Directory&gt;
    </code></p></div>
    This is necessary since multiple <var>URL-paths</var> can map
    to the same filesystem location, potentially bypassing the
    <code class="directive">ScriptAlias</code> and revealing the source code
    of the CGI scripts if they are not restricted by a
    <code class="directive"><a href="../mod/core.html#directory">Directory</a></code> section.</div>

    <p>This directive is equivalent to <code class="directive"><a href="#scriptalias">ScriptAlias</a></code>, but makes use of
    <a class="glossarylink" href="../glossary.html#regex" title="see glossary">regular expressions</a>,
    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 activate the standard <code>/cgi-bin</code>, one
    might use:</p>

    <div class="example"><p><code>
      ScriptAliasMatch ^/cgi-bin(.*) /usr/local/apache/cgi-bin$1
    </code></p></div>

    <p>As for AliasMatch, the full range of <a class="glossarylink" href="../glossary.html#rexex" title="see glossary">regular
    expression</a> power is available.
    For example, it is possible to construct an alias with case-insensitive
    matching of the URL-path:</p>

    <div class="example"><p><code>
      ScriptAliasMatch (?i)^/cgi-bin(.*) /usr/local/apache/cgi-bin$1
    </code></p></div>

    <p>The considerations related to the difference between
    <code class="directive"><a href="#alias">Alias</a></code> and
    <code class="directive"><a href="#aliasmatch">AliasMatch</a></code>
    also apply to the difference between
    <code class="directive"><a href="#scriptalias">ScriptAlias</a></code> and
    <code class="directive"><a href="#scriptaliasmatch">ScriptAliasMatch</a></code>.
    See <code class="directive"><a href="#aliasmatch">AliasMatch</a></code> for
    details.</p>
