-/**

- * TSessionPageStatePersister class

- *

- * TSessionPageStatePersister implements a page state persistent method based on

- * sessions. Page state are stored in user sessions and therefore, this persister

- * requires session to be started and available.

- *

- * TSessionPageStatePersister keeps limited number of history states in session,

- * mainly to preserve the precious server storage. The number is specified

- * by {@link setHistorySize HistorySize}, which defaults to 10.

- *

- * There are a couple of ways to use TSessionPageStatePersister.

- * One can override the page's {@link TPage::getStatePersister()} method and

- * create a TSessionPageStatePersister instance there.

- * Or one can configure the pages to use TSessionPageStatePersister in page configurations

- * as follows,

- * <code>

- *   <pages StatePersisterClass="System.Web.UI.TSessionPageStatePersister" />

- * </code>

- * The above configuration will affect the pages under the directory containing

- * this configuration and all its subdirectories.

- * To configure individual pages to use TSessionPageStatePersister, use

- * <code>

- *   <pages>

- *     <page id="PageID" StatePersisterClass="System.Web.UI.TSessionPageStatePersister" />

- *   </pages>

- * </code>
