Package org.jwall.web.audit.session

The session-package provides some interfaces to implement session trackers.

See: Description

Interface Summary

Interface	Description
HttpProtocol	This interface defines the constants that are part of the HTTP protocol.
SessionContext	This interface defines an abstract session context that is associated with a session-identifier and provides features like setting variables and removing or expiring variables of session scope.
SessionTracker	This interface defines the basic function of a session tracker.

Class Summary

Class	Description
AbstractSessionTracker	This class is an abstract implementation of a simple session tracker and provides the basis for the tracker HeuristicSessionTracker and CookieSessionTracker.
CookieSessionTracker	This tracker creates a session-context wrt to a specific session-cookie.
HeuristicSessionTracker	This heuristic session-tracker implements the session-algorithm used by most popular web-statistic tools, e.g.
Session	This class implements a data storage of some key-value-pairs, all associated with a unique session-id.

Package org.jwall.web.audit.session Description

The session-package provides some interfaces to implement session trackers. The core interfaces are SessionContext, which represents a user session among several requests and SessionTracker, which defines the methods common to all classes that provide session tracking facilities.

In addition to these interfaces the package does include implementations for session trackers based on

• Heuristics, i.e. the client IP address and a time-out value
• Cookie variable, the most common session mechanism.

The cookie-based session tracker is probably the best starting point to implement your own session tracker by either directly extending the cookie-session tracker or using the AbstractSessionTracker as a basis.
