Is the particular interop problem that you want to address caused by a necessity to really process application data and handshake data with arbitrary interleave, or is it rather a problem of getting back into half-duplex operation, i.e. a client being able to continue receiving application data up to a ServerHello when it has sent out ClientHello, or a server being able to continue receiving application data up to a ClientHello (or warning level no-renegotiation alert) after the server has sent a ClientHelloRequest? -Martin Matt Caswell wrote: > >>> 1) Allow interleaved data everywhere except between CCS and Finished, as >>> per the (hopelessly unclear) RFC.
