In  addition, a different replacement strategy than the default <a href="ezcCacheStackLruReplacementStrategy.html">ezcCacheStackLruReplacementStrategy</a> replacement strategy is defined. LFU  removes least frequently used items, while LRU deletes least recently used  items from a storage, if it runs full.<p>Using the $bubbleUpOnRestore option you can determine, that data which is  restored from a lower storage will be automatically stored in all higher  storages again. The problem with this is, that only the attributes that are  used for restoring will be assigned to the item in higher storages. In  addition, the items will be stored with a fresh TTL. Therefore, this  behavior is not recommended.</p><p>If you want to use a cache stack in combination with {@ezcCacheManager}, you  will most likely want to use <a href="ezcCacheStackConfigurator.html">ezcCacheStackConfigurator</a>. This allows  you to let 
 the stack be configured on the fly, when it is used for the first  time in a request.</p><p>Beware, that whenever you change the structure of your stack or the  replacement strategy between 2 requests, you should always perform a  complete <a href="ezcCacheStack.html#methodreset">ezcCacheStack::reset()</a> on it. Otherwise, your cache data  might be seriously broken which will result in undefined behaviour of the  stack. Changing the replacement strategy will most possibly result in an  <a href="ezcCacheInvalidMetaDataException.html">ezcCacheInvalidMetaDataException</a>.</p></div>

+</ol>  $storage2 is defined to store the meta information for the stack. In  addition, a different replacement strategy than the default <a href="../Cache/ezcCacheStackLruReplacementStrategy.html">ezcCacheStackLruReplacementStrategy</a> replacement strategy is defined. LFU  removes least frequently used items, while LRU deletes least recently used  items from a storage, if it runs full.<p>Using the $bubbleUpOnRestore option you can determine, that data which is  restored from a lower storage will be automatically stored in all higher  storages again. The problem with this is, that only the attributes that are  used for restoring will be assigned to the item in higher storages. In  addition, the items will be stored with a fresh TTL. Therefore, this  behavior is not recommended.</p>
+<p>If you want to use a cache stack in combination with {@ezcCacheManager}, you  will most likely want to use <a href="../Cache/ezcCacheStackConfigurator.html">ezcCacheStackConfigurator</a>. This allows  you to let the stack be configured on the fly, when it is used for the first  time in a request.</p>
+<p>Beware, that whenever you change the structure of your stack or the  replacement strategy between 2 requests, you should always perform a  complete <a href="../Cache/ezcCacheStack.html#methodreset">ezcCacheStack::reset()</a> on it. Otherwise, your cache data  might be seriously broken which will result in undefined behaviour of the  stack. Changing the replacement strategy will most possibly result in an  <a href="../Cache/ezcCacheInvalidMetaDataException.html">ezcCacheInvalidMetaDataException</a>.</p>
