Getting a Host: keyword as part of a request is really a protocol violation
if the browser said HTTP/1.0 rather than HTTP/1.1.  But all browsers do this,
except Lynx, and any reasonable web server (Apache and Squid, for examples)
will let you switch web roots based on the Host: keyword, regardless of HTTP
versioning.  It's possible that all you have to do is switch web servers and
your need to burn address space will evaporate immediately.
