<h3>Sommaire</h3>

    <p><code>lbmethod=heartbeat</code> utilise les services du module
    <code class="module"><a href="../mod/mod_heartmonitor.html">mod_heartmonitor</a></code> pour r�partir la charge entre les
    serveurs d'origine qui fournissent des donn�es heartbeat via le
    module <code class="module"><a href="../mod/mod_heartbeat.html">mod_heartbeat</a></code>.</p>

<p>Son algorithme de r�partition de charge favorise les serveurs dont la
capacit� de traitement moyenne r�partie dans le temps est la plus
importante, mais il ne s�lectionne pas forc�ment le serveur qui pr�sente
la disponibilit� instantan�e la plus importante. Les serveurs qui ne
poss�dent aucun client actif sont p�nalis�s, car ils sont consid�r�s
comme non enti�rement initialis�s.</p>
