* Les certificats HTTPS "certifient" un certain domaine, mais le protocole et le cryptage se font au niveau TCP, avant de savoir quel domaine est traité.
* Par défaut, cela signifie que vous ne pouvez avoir qu'un seul certificat HTTPS par adresse IP.
    * Quelle que soit la taille de votre serveur ou la taille de chacune des applications qu'il contient.
    * Il existe cependant une solution à ce problème.
