  37 <h3>Summary</h3>
  38
  39     <p>This module provides authentication front-ends such as
  40     <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code> to authenticate users similar
  41     to anonymous-ftp sites, <em>i.e.</em> have a 'magic' user id
  42     'anonymous' and the email address as a password. These email
  43     addresses can be logged.</p>
  44
  45     <p>Combined with other (database) access control methods, this
  46     allows for effective user tracking and customization according
  47     to a user profile while still keeping the site open for
  48     'unregistered' users. One advantage of using Auth-based user
  49     tracking is that, unlike magic-cookies and funny URL
  50     pre/postfixes, it is completely browser independent and it
  51     allows users to share URLs.</p>
  52
  53     <p>When using <code class="module"><a href="../mod/mod_auth_basic.html">mod_auth_basic</a></code>, this module is invoked
  54     via the <code class="directive"><a href="../mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</a></code>
  55     directive with the <code>anon</code> value.</p>
