Answer 1

The server you connected to did not send a proper HTTP response line. Such a response should consist of a number followed by a human-readable textual description, like:

200 Ok

or

404 Not Found

You need to verify what the server on port 8021 sends. Try using telnet IP 8021 from the terminal, then entering something like GET / HTTP/1.1 plus two newlines to see what is returned by the server.

I note that your v_params string is empty; it may be your server expects at least the empty path (/). However, not sending a properly formatted error code in that case is still a violation of the HTTP standard.
