  <title>Per-user web directories</title>

<summary>
<p>On systems with multiple users, each user can be permitted to have a
    web site in their home directory using the <directive 
    module="mod_userdir">UserDir</directive> directive. Visitors
    to a URL <code>http://example.com/~username/</code> will get content
    out of the home directory of the user "<code>username</code>", out of
    the subdirectory specified by the <directive
    module="mod_userdir">UserDir</directive> directive.</p>

    <title>Setting the file path with UserDir</title>

    <p>The <directive module="mod_userdir">UserDir</directive>
    directive specifies a directory out of which per-user
    content is loaded. This directive may take several different forms.</p>

    <p>If a path is given which does not start with a leading slash, it is
    assumed to be a directory path relative to the home directory of the
    specified user. Given this configuration:</p>

    <example>
      UserDir public_html
    </example>

    <p>the URL <code>http://example.com/~rbowen/file.html</code> will be
    translated to the file path
    <code>/home/rbowen/public_html/file.html</code></p>

    <p>If a path is given starting with a slash, a directory path will be
    constructed using that path, plus the username specified. Given this
    configuration:</p>

    <example>
      UserDir /var/html
    </example>

    <p>the URL <code>http://example.com/~rbowen/file.html</code> will be
    translated to the file path <code>/var/html/rbowen/file.html</code></p>

    <p>If a path is provided which contains an asterisk (*), a path is used
    in which the asterisk is replaced with the username. Given this
    configuration:</p>

    <example>
      UserDir /var/www/*/docs
    </example>

    <p>the URL <code>http://example.com/~rbowen/file.html</code> will be
    translated to the file path
    <code>/var/www/rbowen/docs/file.html</code></p>

  <section id="enable">
    <title>Restricting what users are permitted to use this 
    feature</title>

    <p>Using the syntax shown in the UserDir documentation, you can restrict
    what users are permitted to use this functionality:</p>

    <example>
      UserDir enabled<br />
      UserDir disabled root jro fish
    </example>

    <p>The configuration above will enable the feature for all users
    except for those listed in the <code>disabled</code> statement.
    You can, likewise, disable the feature for all but a few users by
    using a configuration like the following:</p>

    <example>
      UserDir disabled<br />
      UserDir enabled rbowen krietz
    </example>

    <p>See <directive module="mod_userdir">UserDir</directive>
    documentation for additional examples.</p>

  </section>

  <section id="cgi">
  <title>Enabling a cgi directory for each user</title>

   <p>In order to give each user their own cgi-bin directory, you can use
    a <directive module="core" type="section">Directory</directive>
    directive to make a particular subdirectory of a user's home directory
    cgi-enabled.</p>

    <example>
      &lt;Directory /home/*/public_html/cgi-bin/&gt;<br />
       Options ExecCGI<br />
       SetHandler cgi-script<br />
       &lt;/Directory&gt;
    </example>

    <p>Then, presuming that <code>UserDir</code> is set to
    <code>public_html</code>, a cgi program <code>example.cgi</code>
    could be loaded from that directory as:</p>

    <example>
    http://example.com/~rbowen/cgi-bin/example.cgi
    </example>

    <section id="htaccess">
    <title>Allowing users to alter configuration</title>

    <p>If you want to allows users to modify the server configuration in
    their web space, they will need to use <code>.htaccess</code> files to
    make these changed. Ensure that you have set <directive
    module="core">AllowOverride</directive> to a
    value sufficient for the directives that you want to permit the users
    to modify. See the <a href="htaccess.html">.htaccess tutorial</a> for
    additional details on how this works.</p>
