+     * Access Requested:
+     *
+     * READ	       - I only want to READ, if there isn't an entry just fail
+     * WRITE       - I have something new I want to write into the cache, make
+     *               me a new entry and doom the old one, if any.
+     * READ_WRITE  - I want to READ, but I'm willing to update an existing
+     *               entry if necessary, or create a new one if none exists.
+     *
+     *
+     * Access Granted:
+     *
+     * NONE        - No descriptor is provided. You get zilch. Nada. Nothing.
+     * READ		   - You can READ from this descriptor.
+     * WRITE	   - You must WRITE to this descriptor because the cache entry
+     *               was just created for you.
+     * READ_WRITE  - You can READ the descriptor to determine if it's valid,
+     *               you may WRITE if it needs updating.
+     *
+     *
+     * Comments:
+     *
+     * If you think that you might need to modify cached data or meta data,
+     * then you must open a cache entry requesting WRITE access.  Only one
+     * cache entry descriptor, per cache entry, will be granted WRITE access.
+     * 
+     * Usually, you will request READ_WRITE access in order to first test the
+     * meta data and informational fields to determine if a write (ie. going
+     * to the net) may actually be necessary.  If you determine that it is 
+     * not, then you would mark the cache entry as valid (using MarkValid) and
+     * then simply read the data from the cache.
+     *
+     * A descriptor granted WRITE access has exclusive access to the cache
+     * entry up to the point at which it marks it as valid.  Once the cache
+     * entry has been "validated", other descriptors with READ access may be
+     * opened to the cache entry.
+     *
+     * If you make a request for READ_WRITE access to a cache entry, the cache
+     * service will downgrade your access to READ if there is already a
+     * cache entry descriptor open with WRITE access.
+     *
+     * If you make a request for only WRITE access to a cache entry and another
+     * descriptor with WRITE access is currently open, then the existing cache
+     * entry will be 'doomed', and you will be given a descriptor (with WRITE
+     * access only) to a new cache entry.

+ * The nsINetDataCacheRecord represents a single entry in a database that
+ * caches data retrieved from the network. On top of this low-level interface
+ * to the raw record data, the cache manager implements a higher-level record
+ * interface, nsICachedNetData.  Each instance of nsINetDataCacheRecord is
+ * (internally) associated with a parent database, an instance of the
+ * nsINetDataCache interface.  This interface is essentially a pseudo-private
+ * API for the cache manager.  Other clients should never use this interface.
+ *
+ * Each cache record may contain both content and metadata.  The content may
+ * be, for example, GIF image data or HTML, and it is accessed through
+ * nsIChannel's streaming API.  The opaque metadata, which may contain HTTP
+ * headers among other things, is accessed as a contiguous byte array.  Each
+ * entry in the cache is indexed by two different keys: a unique record id
+ * number, generated by the cache, and an opaque string.  The latter contains
+ * the URI and other secondary key information, e.g. HTTP form post key/value
+ * pairs.
+ *
+ * The nsINetDataCacheRecord interface is agnostic as to where the data is
+ * stored and whether the storage is volatile or persistent.  The memory cache,
+ * the disk cache, a flat-file cache and any read-only extension caches must
+ * all implement this interface.
