      <p>mod_cache implements an RFC 2616 compliant HTTP content
      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>
  
      <p>Content stored and retrived keyed to the URL. Content with
      access protections is not cached.</p>

  <usage>
      <p>The <directive>CacheEnable</directive> directive instructs

the
      in-memory cache storage manager implemented by <em>mod_mem_cache</em>. 
      <em>cache_type </em> <em> disk</em> instructs mod_cache to use
the
      cache storage manager implemented by <em>mod_disk_cache </em>. </p>
