    <p>This directive controls the setting of the domain to which
    the tracking cookie applies. If not present, no domain is
    included in the cookie header field.</p>

    <p>The domain string <strong>must</strong> begin with a dot, and
    <strong>must</strong> include at least one embedded dot. That is,
    <code>.example.com</code> is legal, but <code>www.example.com</code> and
    <code>.com</code> are not.</p>

    <div class="note">Most browsers in use today will not allow cookies to be set
    for a two-part top level domain, such as <code>.co.uk</code>,
    although such a domain ostensibly fulfills the requirements
    above.<br />

    These domains are equivalent to top level domains such as
    <code>.com</code>, and allowing such cookies may be a security
    risk. Thus, if you are under a two-part top level domain, you
    should still use your actual domain, as you would with any other top
    level domain (for example <code>.example.co.uk</code>).

    <p>When used, this directive sets an expiry time on the cookie
    generated by the usertrack module. The <em>expiry-period</em>
    can be given either as a number of seconds, or in the format
    such as "2 weeks 3 days 7 hours". Valid denominations are:
    years, months, weeks, days, hours, minutes and seconds. If the expiry
    time is in any format other than one number indicating the
    number of seconds, it must be enclosed by double quotes.</p>

    <p>If this directive is not used, cookies last only for the
    current browser session.</p>

    <p>This directive allows you to change the name of the cookie
    this module uses for its tracking purposes. By default the
    cookie is named "<code>Apache</code>".</p>

    <p>You must specify a valid cookie name; results are
    unpredictable if you use a name containing unusual characters.
    Valid characters include A-Z, a-z, 0-9, "_", and "-".</p>

    <p>This directive controls the format of the cookie header
    field. The three formats allowed are:</p>

    <ul>
      <li><strong>Netscape</strong>, which is the original but now deprecated
      syntax. This is the default, and the syntax Apache has
      historically used.</li>

      <li><strong>Cookie</strong> or <strong>RFC2109</strong>, which is the syntax that
      superseded the Netscape syntax.</li>

      <li><strong>Cookie2</strong> or <strong>RFC2965</strong>, which is the most
      current cookie syntax.</li>
    </ul>

    <p>Not all clients can understand all of these formats, but you
    should use the newest one that is generally acceptable to your
    users' browsers. At the time of writing, most browsers support all
    three of these formats, with <code>Cookie2</code> being the
    preferred format.</p>

    <p>When <code class="module"><a href="../mod/mod_usertrack.html">mod_usertrack</a></code> is loaded, and
    <code>CookieTracking on</code> is set, Apache will send a
    user-tracking cookie for all new requests. This directive can
    be used to turn this behavior on or off on a per-server or
    per-directory basis. By default, enabling
    <code class="module"><a href="../mod/mod_usertrack.html">mod_usertrack</a></code> will <strong>not</strong>
    activate cookies. </p>
