When a browser claims that it supports HTTP/1.1 it doesn't mean that
it uses it for each request. I believe that in general case browser
always uses HTTP/1.0 which is logged in apache log.
I'm not sure how to make the same browser to use HTTP/1.1 as default
protocol. I guess you shouldn't because not all webservers support it
yet :)
Still I think that if Apache returns HTTP/1.1 as protocol then browser
will correctly handle it (multi-part transactions etc.)
