The WebContext is an abstraction to deal with the HTTP request and response.

To specifically deal with the session, it relies on a SessionStore which may be available via the getSessionStore method.

The SessionStore has the following methods:

• getOrCreateSessionId: gets or creates the session identifier and initializes the session with it if necessary
• ` get`: gets the attribute from the session
• set: sets the attribute in the session
• destroySession: destroys the underlying web session
• getTrackableSession: get the native session as a trackable object (for back-channel logout)
• buildFromTrackableSession: builds a new session store from a trackable session (for back-channel logout)
• renewSession: renews the native session by copying all data to a new one.

For example, the JEEContext currently uses the JEESessionStore which relies on the JEE session. In Play, we have a specific cache-based PlayCacheSessionStore as well as in Knox, which has a cookie-based KnoxSessionStore.
