Not easy to answer off the top of my head. But interesting.

That length is the length of packet 1, I guess.

There is no content-type header, right?

I assume here, that the server is smart enough and knows from the
content, how much data he can expect from the client.

Probably a CGI function must be used to handle the POST, but I need a
bit more time to check the details. I do not have any real world
experience with REST. Would it make sense for me to install any simple
REST client for testing (Linux or Windows)?
