<p><code class="module"><a href="/mod/mod_usertrack.html">mod_usertrack</a></code> sets a cookie which can be logged
via <code class="module"><a href="/mod/mod_log_config.html">mod_log_config</a></code> configurable logging formats:</p>
<div class="example"><p><code>

<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>.com</code> are not.</p>
<div class="note">Most browsers in use today will not allow cookies to be set
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

<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>
<div class="example"><p><code>
CookieExpires "3 weeks"
</code></p></div>

<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>
<div class="example"><p><code>
CookieName clicktrack
</code></p></div>

</table>
<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superseded the Netscape syntax.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>
<div class="example"><p><code>
CookieStyle Cookie2
</code></p></div>

<tr><th><a href="directive-dict.html#Syntax">Syntax:</a></th><td><code>CookieTracking on|off</code></td></tr>

</table>
<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>
