Yes, that's what it's called, see:

I'm not sure I understand exactly what you mean by web address here.
I don't think it matters to the web server if you use http or https
with virtual hosting of any flavor.

Name based virtual hosting uses the HTTP/1.1 "Host:" header,
which HTTP/1.1 clients send. This allows the server to know what
host/domain, the client thinks it is connecting to. A normal
HTTP request line only has the request path in it, no hostname,
hence the new header. IP-based virtual hosting works for older
browsers that use HTTP/1.0 and don't send the "Host:" header, and
requires the server to use a separate IP for each virtual domain.
