Actually, it is turning out to be true:

http://ftp.ics.uci.edu/pub/ietf/http/rfc1945.html#Response According to HTTP 1.0, When a request is Simple-Request, it means a VERB URL (without a version) and it generally corresponds to HTTP 0.9 And when a server receives such a Simple-Request, it sends a Simple-Response where it does not send the headers back. I think, the same is exhibited by other Servers as well www.google.com, www.mozilla.org where for Invalid Request without version, you are sending a Simple-Request (HTTP 0.9) style and getting the corresponding response. Yes, but only error or redirect responses: $ nc www.google.fr 80 GET / HTTP/1.0 302 Found Location: http://www.google.fr/ [etc.]

Note that by using nc to test this, you're already generating an illegal request (unless you're doing something very special with your keyboard ;). When you hit return, nc will send \n. However, lines are delimited by \r\n in HTTP.

I doubt this makes a difference to the point being discussed, but it could. I suggest performing your tests with telnet, instead.
