MAJ: J'ai du intégrer cette exemple dans mon application, et pour cela j'ai du revoir tout le code de l'exemple. J'ai donc fais une V2 et une V3, dont le résultat est une dll bien pratique qui doit être insérée dans le dossier /bin/ de votre WebApp. Puis il suffit d'implémenter la classe 'ServerASPNET' qui encapsule toute la complexité du fonctionnement du server ASPNET local. On peut même instancier plusieur 'ServerASPNET', un pour chaque WebApp, et ainsi constituer une ferme de WebApp. A partir de la pourquoi pas redevelopper un serveur Web complet compatible ASPNET ? En particulier il doit être possible de pallier le BUG de redirection à la fin d'un traitement (voir le code).

MAJ V4: J'ai ajouter quelques fonctionnalités indispensables : - Gestion des sous-repertoires de la WebApp (dont App_GlobalRessources) - Gestion des fichiers Non-ASP (images, css, html)
