<compatibility>All forms except the <code>UserDir public_html</code>
form are only available in Apache 1.1 or above. Use of the 
<code>enabled</code> keyword, or <code>disabled</code> with a
list of usernames, is only available in Apache 1.3 and
above.</compatibility>

<usage>

    <p>The <directive>UserDir</directive> directive sets the real
    directory in a user's home directory to use when a request for a
    document for a user is received. <em>Directory-filename</em> is
    one of the following:</p>

    <ul>
      <li>The name of a directory or a pattern such as those shown
      below.</li>

      <li>The keyword <code>disabled</code>. This turns off
      <em>all</em> username-to-directory translations except those
      explicitly named with the <code>enabled</code> keyword (see
      below).</li>

      <li>The keyword <code>disabled</code> followed by a
      space-delimited list of usernames. Usernames that appear in
      such a list will <em>never</em> have directory translation
      performed, even if they appear in an <code>enabled</code>
      clause.</li>

      <li>The keyword <code>enabled</code> followed by a
      space-delimited list of usernames. These usernames will have
      directory translation performed even if a global disable is
      in effect, but not if they also appear in a
      <code>disabled</code> clause.</li>
    </ul>

    <p>If neither the <code>enabled</code> nor the
    <code>disabled</code> keywords appear in the
    <code>Userdir</code> directive, the argument is treated as a
    filename pattern, and is used to turn the name into a directory
    specification. A request for
    <code>http://www.foo.com/~bob/one/two.html</code> will be
    translated to:</p>

<table>
<tr><th>UserDir directive used</th>
<th>Translated path</th></tr>
<tr><td>UserDir public_html</td><td>~bob/public_html/one/two.html</td></tr>
<tr><td>UserDir /usr/web</td><td>/usr/web/bob/one/two.html</td></tr>
<tr><td>UserDir /home/*/www</td><td>/home/bob/www/one/two.html</td></tr>
</table>

    <p>The following directives will send redirects to the client:</p> 

<table>
<tr><th>UserDir directive used</th>
<th>Translated path</th></tr>
<tr><td>UserDir http://www.foo.com/users</td><td>http://www.foo.com/users/bob/one/two.html</td></tr>
<tr><td>UserDir
http://www.foo.com/*/usr</td><td>http://www.foo.com/bob/usr/one/two.html</td></tr>
<tr><td>UserDir
http://www.foo.com/~*/</td><td>http://www.foo.com/~bob/one/two.html</td></tr>
</table> 

<note>
      <strong>Be careful when using this directive; for instance,
      <code>"UserDir ./"</code> would map
      <code>"/~root"</code> to <code>"/"</code> - which is probably
      undesirable. If you are running Apache 1.3 or above, it is
      strongly recommended that your configuration include a
      "<code>UserDir disabled root</code>" declaration.
      See also the <directive module="core">Directory</directive>
      directive and the <a href="../misc/security_tips.html">Security
      Tips</a> page for more information.</strong>
</note>

<p>Additional examples:</p>

<p>To allow a few users to have <code>UserDir</code> directories, but
not anyone else, use the following:</p>

<example>
UserDir disabled<br />
UserDir enabled user1 user2 user3
</example>

<p>To allow most users to have <code>UserDir</code> directories, but
deny this to a few, use the following:</p>

<example>
UserDir enabled<br />
UserDir disabled user4 user5 user6
</example>
