correct. there's a specific technical problem due to the way that the https
protocol is designed; it's a chicken-and-egg problem.

specifically, name based identification of sites is based on the HTTP host
request-header field. in https, the certificates are processed before the
Host request-header is transmitted; Host is supposed to be inside the
encrypted tunnel.

a different design might have permitted named based https identification of
virtual web site, but they did what they did.
