411 Length Required

The server refuses to accept the request without a defined Content- Length. The client MAY repeat the request if it adds a valid Content-Length header field containing the length of the message-body in the request message.

Cannot reproduce; tested both the "fully automatic" and the "semi-automatic" method. Please try again and provide more details.

The problem may be that I'm using proxy server at work. Cannot check without proxy now.
