What libcurl version are you using? The heuristic used to determine HTTP
version number changed in 7.19.1 so try the latest version if you aren't
already. libcurl will always use HTTP/1.0 when doing CONNECT requests, but
otherwise it should be using 1.1 when requested (as you are). Can you show
a log of a full authentication session that shows the problem?
