Vous pouvez ajouter des paramètres dans votre http balise comme suit:

<http auto-config="false" disable-url-rewriting="true">

Si vous n'êtes pas à l'aide de Servlet 3.0, vous pouvez également réaliser cela à l'aide d'un PrettyFaces Règle de Réécriture: http://ocpsoft.org/support/topic/url-rewrite-removing-the-jsessionid-from-the-url#post-410
