  59.     <p>The <code class="directive">UserDir</code> directive sets the real
  60.     directory in a user's home directory to use when a request for a
  61.     document for a user is received. <em>Directory-filename</em> is
  62.     one of the following:</p>
  63.  
  64.     <ul>
  65.       <li>The name of a directory or a pattern such as those shown
  66.       below.</li>
  67.  
  68.       <li>The keyword <code>disabled</code>. This turns off
  69.       <em>all</em> username-to-directory translations except those
  70.       explicitly named with the <code>enabled</code> keyword (see
  71.       below).</li>
  72.  
  73.       <li>The keyword <code>disabled</code> followed by a
  74.       space-delimited list of usernames. Usernames that appear in
  75.       such a list will <em>never</em> have directory translation
  76.       performed, even if they appear in an <code>enabled</code>
  77.       clause.</li>
  78.  
  79.       <li>The keyword <code>enabled</code> followed by a
  80.       space-delimited list of usernames. These usernames will have
  81.       directory translation performed even if a global disable is
  82.       in effect, but not if they also appear in a
  83.       <code>disabled</code> clause.</li>
  84.     </ul>
  85.  
  86.     <p>If neither the <code>enabled</code> nor the
  87.     <code>disabled</code> keywords appear in the
  88.     <code>Userdir</code> directive, the argument is treated as a
  89.     filename pattern, and is used to turn the name into a directory
  90.     specification. A request for
  91.     <code>http://www.foo.com/~bob/one/two.html</code> will be
  92.     translated to:</p>
  93.  
  94. <table>

  96. <th>Translated path</th></tr>
  97. <tr><td>UserDir public_html</td><td>~bob/public_html/one/two.html</td></tr>

  99. <tr><td>UserDir /home/*/www</td><td>/home/bob/www/one/two.html</td></tr>
  100. </table>
  101.  
  102.     <p>The following directives will send redirects to the client:</p>

  106. <th>Translated path</th></tr>

  114. <div class="note">
  115.       <strong>Be careful when using this directive; for instance,
  116.       <code>"UserDir ./"</code> would map <code>"/~root"</code> to
  117.       <code>"/"</code> - which is probably undesirable. It is strongly
  118.       recommended that your configuration include a "<code>UserDir
  119.       disabled root</code>" declaration.  See also the <code class="directive"><a href="../mod/core.html#directory">Directory</a></code> directive and the <a href="../misc/security_tips.html">Security Tips</a> page for
  120.       more information.</strong>
  121. </div>
  122.  
  123. <p>Additional examples:</p>
  124.  
  125. <p>To allow a few users to have <code>UserDir</code> directories, but
  126. not anyone else, use the following:</p>
  127.  
  128. <div class="example"><p><code>
  129. UserDir disabled<br />
  130. UserDir enabled user1 user2 user3
  131. </code></p></div>
  132.  
  133. <p>To allow most users to have <code>UserDir</code> directories, but
  134. deny this to a few, use the following:</p>
  135.  
  136. <div class="example"><p><code>
  137. UserDir enabled<br />
  138. UserDir disabled user4 user5 user6
  139. </code></p></div>
  140.  
  141. <p>It is also possible to specify alternative user directories.
  142. If you use a command like:</p>
  143. <div class="example"><p><code>
  144. Userdir public_html /usr/web http://www.foo.com/
  145. </code></p></div>
  146. <p>With a request for http://www.foo.com/~bob/one/two.html, will try to 
  147. find the page at ~bob/public_html/one/two.html first, then
  148. /usr/web/bob/one/two.html, and finally it will send a redirect
  149. to http://www.foo.com/bob/one/two.html.</p>
  150. <p>If you add a redirect, it must be the last alternative in the list.
  151. Apache cannot determine if the redirect succeeded or not, so if you have
  152. the redirect earlier in the list, that will always be the alternative
  153. that is used.</p>
  154.  
  155. <p>User directory substitution is not active by default in versions
  156. 2.1.4 and later.  In earlier versions, <code>UserDir public_html</code>
  157. was assumed if no <code class="directive"><a href="#userdir">UserDir</a></code>
  158. directive was present.</p>
