/** Usage **
1. Start a SSL server in terminal 1
  $ openssl s_server -cert test_cert.pem -key test_key.pem
  (..lots of SSL logs..)

2. Run the client in terminal 2 - don't reuse sessions
  $ node client.js
  session reused: false

3. Run the client again and reuse sessions
  $ node client.js reuse
  session reused: true
