until #25 shakes out

Indeed, there exists a variety of ways to go around this limitation if the server supports it. Unfortunately none of these are standard so I don't intend to add them to the readme (there are way too many edge cases and hacks around the HTTP protocol ).
I'll link to this thread so people can find the information should they need it.

Thanks for the contribution!
