Transparent (redirecting) proxy with BaseHTTPServer

[aurora]

It should be very safe to count on the host header. Maybe some really  
really old browser would not support that. But they probably won't work in  
today's WWW anyway. Majority of today's web site is likely to be virtually  
hosted. One Apache maybe hosting for 50 web addresses. If a client strip  
the host name and not sending the host header either the web server  
wouldn't what address it is really looking for. If you caught some request  
that doesn't have host header it is a good idea to redirect them to a  
browser upgrade page.
