<ul>
|

<li class="level1"><div class="li"> Portal does not store any data outside the session database, so you can have many portal servers using the same HTTP host name</div>
|
|
</li>
|

<li class="level1"><div class="li"> Tous les agents téléchargent intégralement la configuration, donc plusieurs serveurs peuvent servir le même hôte virtuel</div>

Il faut juste partager les bases de données de configuration et des sessions entre ces serveurs :
