i have java tls client can send series of requests server, each followed response server. however, there many different servers. "multi-message" servers keep connection open after first request, subsequent requests can sent on first connection. others "single-message" servers close connection after each message , new connection required subsequent messages. there no priori way client know type of server talking to, nor fix servers. it desirable single-message serves able resume session without full handshake. my original client code tried send subsequent requests down same connection. if failed opened new connection server. handle both single , multi-message servers. however, failure when sending second message single-message severs seems kill session resumption. my dirty work around notice if message fails , assume talking single-message server, in case client explicitly closes socket after each response has been received. enables subsequent co
