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.
