Renegotiation is a huge win for performance.

Despite the common belief, SSL negotiation introduces significant overhead and latency.

I think you have session resumption in mind. Renegotiation is different and involves performing more than one handshake per connection.

Oh, thanks. Hm...then I agree with parent; I have no idea what renegotiation is for.

But under what circumstances is it used? Why would you renegotiate in the middle of a session?
