@zzsoszz & @snail007, hello!
I'm afraid we are facing the same issue but on Windows. Unfortunately this is not only a warning, traffic is not passed if such addresses are requested.
It turns out that proxy doesn't respect short hostnames in HTTP GET/POST even if they properly come from /etc/hosts or explicitly added as a command line parameter. Other commands like ping are certainly able to use these hostnames.

Can anybody tell me if there are plans to address this issue?
