e, then you <b>must</b> make sure that
<code>mod_ifsession</code> is loaded <b>last</b>:
<pre>
  &lt;IfModule mod_dso.c&gt;
    LoadModule mod_sql.c
    LoadModule mod_sql_mysql.c
    LoadModule mod_tls.c
    LoadModule mod_rewrite.c
    <b>LoadModule mod_ifsession.c</b>
  &lt;/IfModule&gt;
</pre>
Failure to ensure that <code>mod_ifsession</code> is loaded last will mean
that the per-user/group/class functionality will not work as you expect.
