Each SSL connection involves one session at a time, but * that session may be used on many connections between those entities, * simultaneously or sequentially. The session used on a connection may * also be replaced by a different session. Sessions are created, or * rejoined, as part of the SSL handshaking protocol. Sessions may be * invalidated due to policies affecting security or resource usage, * or by an application explicitly calling invalidate. * Session management policies are typically used to tune performance. * *

In addition to the standard session attributes, SSL sessions expose * these read-only attributes:

* *
• Peer Identity. Sessions are between a particular * client and a particular server. The identity of the peer may * have been established as part of session setup. Peers are * generally identified by X.509 certificate chains. * *
• Cipher Suite Name. Cipher suites describe the * kind of cryptographic protection that's used by connections * in a particular session. * *
• Peer Host. All connections in a session are * between the same two hosts. The address of the host on the other * side of the connection is available. * *

Sessions may be explicitly invalidated. Invalidation may also * be done implicitly, when faced with certain kinds of errors. * * @since 1.4 * @version 1.26 * @author David Brownell */ public interface SSLSession { /** * Returns the identifier assigned to this Session. * * @return the Session identifier */ public byte[] getId(); /** * Returns the context in which this session is bound. *
