Examples of org.apache.cocoon.environment.Session

org.apache.cocoon.environment.Session
Provides a way to identify a user across more than one page request or visit to a Web site and to store information about that user.
Cocoon uses this interface to create a session between a client and the "cocoon server". The session persists for a specified time period, across more than one connection or page request from the user. A session usually corresponds to one user, who may visit a site many times. The server can maintain a session in many ways such as using cookies or rewriting URLs.
This interface allows Cocoon to
- View and manipulate information about a session, such as the session identifier, creation time, and last accessed time
- Bind objects to sessions, allowing user information to persist across multiple user connections
Session information is scoped only to the current context (Context), so information stored in one context will not be directly visible in another. @author Carsten Ziegeler @version CVS $Revision: 1.1.1.1 $ $Date: 2001/05/09 20:49:43 $
