CCacheHttpSession implements a session component using cache as storage medium.
The cache being used can be any cache application component implementing ICache interface. The ID of the cache application component is specified via cacheID, which defaults to 'cache'.
Beware, by definition cache storage are volatile, which means the data stored on them may be swapped out and get lost. Therefore, you must make sure the cache used by this component is NOT volatile. If you want to use CDbCache as storage medium, use CDbHttpSession is a better choice.
