I thought of way to send some kind of headers, but I am very new to
programming and I don't know how.
I wonder, because data is transferred as Bytes, should the headers be binary
or string.
the simplest thing that I can figure is to use an integer as header and
based on the integer to decide what kind of data is transmitted. Just can't
figure out how to attach the header to the sent data and how to separate it
at the receiver.
