Perhaps not. RFC 2817 ("Upgrading to TLS Within HTTP/1.1", May 2000)
appears to contain the following in its abstract:

"This memo explains how to use the Upgrade mechanism in HTTP/1.1 to
initiate Transport Layer Security (TLS) over an existing TCP connection.
...
It also enables "virtual hosting", so a single HTTP + TLS server can
disambiguate traffic intended for several hostnames at a single IP
address."
