     cache that can be used to cache either local or proxied content.
     mod_cache requires the services of one or more storage
     management modules. Two storage management modules are included in
-    the base Apache distribution: <em>mod_disk_cache</em> implements a
-    disk based storage manager (generally used for proxy caching) and 
-    <em>mod_mem_cache</em> implements an in-memory based storage
-    manager (primarily useful for caching local content). </p>

+    can be configured to operate in two modes: caching open file
+    descriptors or caching objects in heap storage. <em>mod_mem_cache</em>
