I use Stunnel 4.03 I have been working on a project with some slow POS equipment trying to do SSL connections. Because of the slow processors on these devices, we are trying to speed up the connection and transaction. The concept of "session resumption" came up. What is the best way to setup Stunnel to make subsequent connections faster with session resumption.
Thanks,

Stunnel will use session-id caching (session resupmtion) by default if available. The client, when connecting, says "Hey, I've got this old session-id, want to use it?" and if the server is cool with it, it will skip the normal/computationally intensive handshake.
When you run Stunnel, include the full debugging and look for 'session id reuse' in the output - if you're getting sessions reused, then everything's working correctly.
