/**
* CStatePersister implements a file-based persistent data storage.
*
* It can be used to keep data available through multiple requests and sessions.
*
* By default, CStatePersister stores data in a file named 'state.bin' that is located
* under the application {@link CApplication::getRuntimePath runtime path}.
* You may change the location by setting the {@link stateFile} property.
*
* To retrieve the data from CStatePersister, call {@link load()}. To save the data,
* call {@link save()}.
*
* Comparison among state persister, session and cache is as follows:
* <ul>
* <li>session: data persisting within a single user session.</li>
* <li>state persister: data persisting through all requests/sessions (e.g. hit counter).</li>
* <li>cache: volatile and fast storage. It may be used as storage medium for session or state persister.</li>
* </ul>
*
* Since server resource is often limited, be cautious if you plan to use CStatePersister
* to store large amount of data. You should also consider using database-based persister
* to improve the throughput.
*
* CStatePersister is a core application component used to store global application state.
* It may be accessed via {@link CApplication::getStatePersister()}.
* page state persistent method based on cache.
