 <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>

     <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>
 <table class="directive">

 <tr><th><a href="directive-dict.html#Status">Status:</a></th><td>Extension</td></tr>
 <tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_vhost_alias</td></tr>
 </table>

     <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>

 <tr><th><a href="directive-dict.html#Module">Module:</a></th><td>mod_vhost_alias</td></tr>
 </table>

 <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
     determine where Apache will find CGI scripts in a similar
     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>

	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>

	<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>
