that is a standard HTTP post and thus sends HTTP request headers
before the textarea form payload.

what Robert indicated is that he thinks it is highly unlikely that you
could use a browser to connect and send AUTHENTICATE before anything
else, like the request headers.

the challenge / response handshake he suggested is an interesting
option for authenticating to the control port; it would indeed
eliminate any blind injection attacks, while still making it trivial
to use the control port legitimately.
