<h3>Summary</h3>

    <p>This module creates dynamically configured virtual hosts, by
    allowing the IP address and/or the <code>Host:</code> header of
    the HTTP request to be used as part of the pathname to
    determine what files to serve. This allows for easy use of a
    huge number of virtual hosts with similar configurations.</p>
    
    <div class="note"><h3>Note</h3>
      <p>If <code class="module"><a href="../mod/mod_alias.html">mod_alias</a></code> or <code class="module"><a href="../mod/mod_userdir.html">mod_userdir</a></code> are
      used for translating URIs to filenames, they will override the
      directives of <code class="module"><a href="../mod/mod_vhost_alias.html">mod_vhost_alias</a></code> described below. For
      example, the following configuration will map <code>
      /cgi-bin/script.pl</code> to <code>
      /usr/local/apache2/cgi-bin/script.pl</code> in all cases:</p>

      <div class="example"><p><code>

<h2><a name="interpol" id="interpol">Directory Name Interpolation</a></h2>
    

    <p>All the directives in this module interpolate a string into
    a pathname. The interpolated string (henceforth called the
    "name") may be either the server name (see the <code class="directive"><a href="../mod/core.html#usecanonicalname">UseCanonicalName</a></code>
    directive for details on how this is determined) or the IP
    address of the virtual host on the server in dotted-quad
    format. The interpolation is controlled by specifiers inspired
    by <code>printf</code> which have a number of formats:</p>

<table>

<tr><td><code>%%</code></td>
<td>insert a <code>%</code></td></tr>

<tr><td><code>%p</code></td>
<td>insert the port number of the virtual host</td></tr>

<tr><td><code>%N.M</code></td>
<td>insert (part of) the name</td></tr>
     
</table>

    <p><code>N</code> and <code>M</code> are used to specify
    substrings of the name. <code>N</code> selects from the
    dot-separated components of the name, and <code>M</code>
    selects characters within whatever <code>N</code> has selected.
    <code>M</code> is optional and defaults to zero if it isn't
    present; the dot must be present if and only if <code>M</code>
    is present. The interpretation is as follows:</p>

    <table>
      
      <tr><td><code>0</code></td>
      <td>the whole name</td></tr>

      <tr><td><code>1</code></td>
      <td>the first part</td></tr>

      <tr><td><code>2</code></td>
      <td>the second part</td></tr>

      <tr><td><code>-1</code></td>
      <td>the last part</td></tr>

      <tr><td><code>-2</code></td>
      <td>the penultimate part</td></tr>

      <tr><td><code>2+</code></td>
      <td>the second and all subsequent parts</td></tr>

      <tr><td><code>-2+</code></td>
      <td>the penultimate and all preceding parts</td></tr>

      <tr><td><code>1+</code> and <code>-1+</code></td>
      <td>the same as <code>0</code></td></tr>
    </table>

    <p>If <code>N</code> or <code>M</code> is greater than the number
    of parts available a single underscore is interpolated. </p>

<h2><a name="examples" id="examples">Examples</a></h2>
    

    <p>For simple name-based virtual hosts you might use the
    following directives in your server configuration file:</p>

    <div class="example"><p><code>
      UseCanonicalName    Off<br />
      VirtualDocumentRoot /usr/local/apache/vhosts/%0
    </code></p></div>

    <p>A request for
    <code>http://www.example.com/directory/file.html</code> will be
    satisfied by the file
    <code>/usr/local/apache/vhosts/www.example.com/directory/file.html</code>.
    </p> 

    <p>For a very large number of virtual hosts it is a good idea
    to arrange the files to reduce the size of the
    <code>vhosts</code> directory. To do this you might use the
    following in your configuration file:</p>

    <div class="example"><p><code>
      UseCanonicalName    Off<br />
      VirtualDocumentRoot /usr/local/apache/vhosts/%3+/%2.1/%2.2/%2.3/%2
    </code></p></div>

    <p>A request for
    <code>http://www.domain.example.com/directory/file.html</code>
    will be satisfied by the file
    <code>/usr/local/apache/vhosts/example.com/d/o/m/domain/directory/file.html</code>.</p>

    <p>A more even spread of files can be achieved by hashing from the
    end of the name, for example: </p>

<div class="example"><p><code>
    VirtualDocumentRoot /usr/local/apache/vhosts/%3+/%2.-1/%2.-2/%2.-3/%2
</code></p></div>

    <p>The example request would come from
    <code>/usr/local/apache/vhosts/example.com/n/i/a/domain/directory/file.html</code>.</p>

    <p>Alternatively you might use: </p>

<div class="example"><p><code>
    VirtualDocumentRoot /usr/local/apache/vhosts/%3+/%2.1/%2.2/%2.3/%2.4+
</code></p></div>

    <p>The example request would come from
    <code>/usr/local/apache/vhosts/example.com/d/o/m/ain/directory/file.html</code>.</p>

    <p>For IP-based virtual hosting you might use the following in
    your configuration file:</p>

    <div class="example"><p><code>
      UseCanonicalName DNS<br />
      VirtualDocumentRootIP /usr/local/apache/vhosts/%1/%2/%3/%4/docs<br />
      VirtualScriptAliasIP  /usr/local/apache/vhosts/%1/%2/%3/%4/cgi-bin
    </code></p></div>

    <p>A request for
    <code>http://www.domain.example.com/directory/file.html</code>
    would be satisfied by the file
    <code>/usr/local/apache/vhosts/10/20/30/40/docs/directory/file.html</code>
    if the IP address of <code>www.domain.example.com</code> were
    10.20.30.40. A request for
    <code>http://www.domain.example.com/cgi-bin/script.pl</code> would
    be satisfied by executing the program
    <code>/usr/local/apache/vhosts/10/20/30/40/cgi-bin/script.pl</code>.</p>

    <p>If you want to include the <code>.</code> character in a
    <code>VirtualDocumentRoot</code> directive, but it clashes with
    a <code>%</code> directive, you can work around the problem in
    the following way:</p>

<div class="example"><p><code>
    VirtualDocumentRoot /usr/local/apache/vhosts/%2.0.%3.0
</code></p></div>

    <p>A request for
    <code>http://www.domain.example.com/directory/file.html</code>
    will be satisfied by the file
    <code>/usr/local/apache/vhosts/domain.example/directory/file.html</code>.</p>
     
    <p>The <code class="directive"><a href="../mod/mod_log_config.html#logformat">LogFormat</a></code>
    directives <code>%V</code> and <code>%A</code> are useful
    in conjunction with this module.</p>
</div>
<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
<div class="directive-section"><h2><a name="VirtualDocumentRoot" id="VirtualDocumentRoot">VirtualDocumentRoot</a> <a name="virtualdocumentroot" id="virtualdocumentroot">Directive</a></h2>

    <p>The <code class="directive">VirtualDocumentRoot</code> directive allows you to
    determine where Apache will find your documents based on the
    value of the server name. The result of expanding
    <em>interpolated-directory</em> is used as the root of the
    document tree in a similar manner to the <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> directive's argument. 
    If <em>interpolated-directory</em> is <code>none</code> then
    <code class="directive">VirtualDocumentRoot</code> is turned off. This directive 
    cannot be used in the same context as <code class="directive"><a href="#virtualdocumentrootip">VirtualDocumentRootIP</a></code>.</p>

<p>The <code class="directive">VirtualDocumentRootIP</code> directive is like the
    <code class="directive"><a href="#virtualdocumentroot">VirtualDocumentRoot</a></code>
    directive, except that it uses the IP address of the server end
    of the connection for directory interpolation instead of the server
    name.</p>

    <p>The <code class="directive">VirtualScriptAlias</code> directive allows you to

    manner to <code class="directive"><a href="#virtualdocumentroot">VirtualDocumentRoot</a></code> does for other documents. It matches
    requests for URIs starting <code>/cgi-bin/</code>, much like <code class="directive"><a href="../mod/mod_alias.html#scriptalias">ScriptAlias</a></code>
    <code>/cgi-bin/</code> would.</p>
