N00b - logging stream request / response

[Joel Parker]

What I am trying to do is create an open proxy that listens to TLS from
many servers and de-crypts the traffic with the appropriate keys, log the
de-crytped request / response then re-encrypt with different certs and send
to an upstream server. My thought was theat a stream block would help me
accomplish this.
