Hello all,
when sending data it's often necessary to inform the server about what kind of data he gets so that he can react accordingly. To achieve that, I need control messages that I can append to any message. That works pretty easy when sending strings, but I don't know how I could tell the server that he will receive a serialized object, because I can't append a string at the beginning of an OutputStream. It would be very nice if someone could help me here.
