/**
 * CHttpSession提供了session级的数据管理和相关配置
 *
 * 开启session 调用 {@link open()};
 * 完成和发送session数据，调用 {@link close()};
 * 清除session,调用{@link destroy()}.
 *
 *
 * CHttpSession can be used like an array to set and get session data. For example,
 * <pre>
 *   $session=new CHttpSession;
 *   $session->open();
 *   $value1=$session['name1'];  // get session variable 'name1'
 *   $value2=$session['name2'];  // get session variable 'name2'
 *   foreach($session as $name=>$value) // traverse all session variables
 *   $session['name3']=$value3;  // set session variable 'name3'
 * </pre>
 *
 * The following configurations are available for session:
 * <ul>
 * <li>{@link setSessionID sessionID};</li>
 * <li>{@link setSessionName sessionName};</li>
 * <li>{@link autoStart};</li>
 * <li>{@link setSavePath savePath};</li>
 * <li>{@link setCookieParams cookieParams};</li>
 * <li>{@link setGCProbability gcProbability};</li>
 * <li>{@link setCookieMode cookieMode};</li>
 * <li>{@link setUseTransparentSessionID useTransparentSessionID};</li>
 * <li>{@link setTimeout timeout}.</li>
 * </ul>
 * See the corresponding setter and getter documentation for more information.
 * Note, these properties must be set before the session is started.
 *
 * CHttpSession can be extended to support customized session storage.
 * Override {@link openSession}, {@link closeSession}, {@link readSession},
 * {@link writeSession}, {@link destroySession} and {@link gcSession}
 * and set {@link useCustomStorage} to true.
 * Then, the session data will be stored and retrieved using the above methods.
 *
 * CHttpSession is a Web application component that can be accessed via
 * {@link CWebApplication::getSession()}.
