This kind of depends on what you're asking for? Do you mean, is there a way to implement this yourself in your own client/server application architecure? Then 'Certainly!' If you mean hooking up this sort of functionality to some other application, or adding the capability to a client without having any control over the server, then I'd say 'I don't know.'

When I've done this in the past, I have my servers response to a client begin with a preamble that includes the length, in bytes, of the response as a whole. Then all the client has to do is keep a running total of the number of bytes that have come in on the socket. HTTP does the same thing with the Content-Length header.
