Class Session

org.shredzone.acme4j.Session
public class Session extends Object
A Session tracks the entire communication with a CA.

To create a session instance, use its constructor. It requires the URI of the ACME server to connect to. This can be the location of the CA's directory (via http or https protocol), or a special URI (via acme protocol). See the documentation about valid URIs.
