The SessionID property returns the session identification for this user. Each session has a unique identifier that is generated by the server when the session is created. The session ID is returned as data type LONG.
Do not use the SessionID property to generate primary key values for a database application. This is because if the Web server is restarted, some SessionID values may be the same as those generated before the server was stopped. Instead, you should use an auto-increment column data type.
