title: TLS session reuse over new TCP connection
body: <p>This is after my <a href="https://stackoverflow.com/questions/4705715/http-persistent-connection-and-ssl-session">question about http and tls</a>.<br>
  It seems that there is no mandate per RFC to invalidate an established TLS session if the underlying TCP connection is closed (and then reopened).<br>
  Is it safe to reuse the established TLS session over the new TCP connection?<br>
  Are there any known attacks (even at theoritical level) that could exploit this?  </p>
  
  <p>Thank you  </p>
