+ <p>The <code class="directive">SessionExpiryUpdateInterval</code> directive allows
+ sessions to avoid the cost associated with writing the session each request
+ when only the expiry time has changed. This can be used to make a website
+ more efficient or reduce load on a database when using
+ <code class="module"><a href="../mod/mod_session_dbd.html">mod_session_dbd</a></code>. The session is always written if the data
+ stored in the session has changed or the expiry has changed by more than the
+ configured interval.</p>
+
+ <p>Setting the interval to zero disables this directive, and the session
+ expiry is refreshed for each request.</p>
+
+ <p>This directive only has an effect when combined with
+ <code class="directive"><a href="#sessionmaxage">SessionMaxAge</a></code> to enable session
+ expiry. Sessions without an expiry are only written when the data stored in
+ the session has changed.</p>
+
+ <div class="warning"><h3>Warning</h3>
+ <p>Because the session expiry may not be refreshed with each request, it's
+ possible for sessions to expire up to <var>interval</var> seconds early.
+ Using a small interval usually provides sufficient savings while having a
