HEAD / HTTP/1.0

I have tried some simple tricks to do web server fingerprinting by issuing "HEAD / HTTP/1.0" after telnet to port 80 of the web server IP address:

**** capture *****

# telnet 58.64.165.185 80
Trying 58.64.165.185...
Connected to 58.64.165.185.
Escape character is '^]'.
HEAD / HTTP/1.0
[Note :two CR pressed afterwards]
HTTP/1.1 200 OK
Content-Length: 5482
Content-Type: text/html
Content-Location: http://58.64.165.185/Index.html

**** End of capture *****

I remember two other methods to do the same; one is httprint and the other is nmap.
