Issue with SSL web server


I'm facing very strange behavior.

We do have one virtual server with SSL and several without it (deactivated in enabled features).

When one of our customer is trying to reach his non ssl site with https, he is reaching the ssl enabled one, even if he is using is own URL.

How could we prevent this behavior in displaying, for example, a page telling that the non ssl site has no certificate, or just forwarding to http instead of https ?
