I missed the context of this function, but it seems like you probably
mean to send:
Content-Type: application/x-www-form-urlencoded

The context is a bit strange, these POST transactions are being used to
send data packets, since it's really the only way to send data to a
server-side PHP script. The scripts involved are used to tunnel
arbitrary TCP/IP data over a standard HTTP connection. The keepalive
means that many POST transactions can be done in one connection, saving
the latency and overhead involved in establishing new TCP/IP
connections. And the content type of an octet stream is used because
x-www-form-urlencoded would have to be decoded by the script on the
server side. With an octet stream, the server-side script can just read
the data in from php://input.
Thanks for the hint on the Connection header. It'll save me from more
overhead :)
