The Session object is an ObjectDictionary that you can use to store information needed for a particular user session. Variables stored in the Session object are not discarded when the user jumps between pages in the application; instead, these variables persist for the entire user session.
The Web server automatically creates a Session object when a Web page from the application is requested by a user who does not already have a session. The server destroys the Session object when the session expires or is abandoned.
One common use for the Session object is to store user preferences that were set on a previous visit to the Web application (such as high, medium, or low graphics).
Note Session state is only maintained for browsers that support cookies.
public class Session extends ObjectDictionary { public ObjectDictionary staticObjects; public String getSessionID(); public int getTimeout(); public void setTimeout(int timeout); public int getLCID(); public void setLCID(int lcid); public int getCodePage(); public void setCodePage(int cp); public void abandon(); }
public ObjectDictionary staticObjects;
Contains all the objects created with the <OBJECT> tag and the given session scope.
public String getSessionID( );
Returns the session identification for this user.
public int getTimeout( );
public void setTimeout(int timeout);
Provides the timeout period for the application's session state, in minutes.
public int getLCID( );
public void setLCID(int lcid);
Identifies locales.
public int getCodePage( );
public void setCodePage(int cp);
Maps symbols.
public void abandon( );
Destroys a Session object and releases its resources.
