Out of interest which part of which rfc (2616 / 2068) says that connection: keep-alive
is invalid for http/1.1?
I see this header send frequently by browsers that speak http/1.1 (of course
this does not mean that this is rfc compliant :-)

Agreed. But I actually only do this when I sent an HTTP/1.1 request.
BTW: This is how the code currently works and this is not changed by my patch.

Another question: Do you see the need for some kind of detection code on the first
request to a backend server whether it speaks HTTP/1.1 or only HTTP/1.0?
