The TCPIP.HTTP_PUT_FILE("url","header","file_to_read")
function creates a new thread. Thread posts data to a WWW server (POST): When thread to terminate, it will cause your callback function WM_PUTFILE(ThreadId, error).

1. You can use the HTTPS resource. https://...
2. You can use the basic authentication for WWW pages. Set username/password in URL (protocol://username:password@hostname/path_to_file), otherwise you must fill the dialog form.
3. When thread to terminate, it will cause your function WM_PUTFILE(ThreadId, error) from script (your callback function). You can see the error codes (~HTTP_STATUS_OK == 200), and standard system error code (for file operations).
4. Return value: If the function succeeds, the return value is a ThreadId to the new thread. If the function fails, the return value is 0.
