What would be in the header?  All IP has in the header to differentiate
connections is IP address and port number.  For example, if I wanted to
access the Mississauga Library ebook collection, I could open a browser
to 13.92.99.128 and it would connect to port 443 for https.  I have not
provided any other information.  So, how would the appropriate server be
accessed from that, when multiple servers share a single IP?
