Implementing messaging protocols (IOCP socket server)

Hi,

I try to implement a messaging protocol in my IOCP based socket server. I
decide to use message header approach in my implementation. The header will
simply contain length of the actual message. If, for example, length of the
header is 5, first I will post a WSARecv () with a 5-byte buffer.When this
function completes, one of my IOCP workers will get the header(i.e. length
of the message body) and post another WSARecv () to get actual message. The
problem is that if a client application sends a message with wrong header
then the server gets wrong message length and communication between the
server and that client is broken (most likely remain broken along that
session). Do you have recommendations about this issue and about building
messaging protocols in general?

Thanks in advance.
