[zeromq-dev] ZMQ_STREAM interraction with ZMTP ?

[Pieter Hintjens]

Please read my previous emails about proxying the CURVE handshake.
What I said still applies. The proxy has to parse the client's CURVE
commands and reply with valid CURVE commands. Using a STREAM socket it
can read the raw frames but then MUST pass them onto the worker, which
will generate the valid replies, which the proxy must then send back
to the client.
