Several HTTPS sites on the same server! possible?

[abbd]

Hello,

I am able to install multiple sites in http on the same server (using the http header).
unfortunatly i can't install it in https, I installed the certificate on port 443 for the first site then what must be done to the second site? Port 443 is used by the first site, Thanks for your help.

NB: I use IIS v6.0
