+/**
+ * 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.

+//    First checked in on 98/11/20 by John R. McMullen in the wrong directory.
+//    Checked in again 98/12/04.
+//    Polished version 98/12/08.
+
+//========================================================================================
+//
+//  Classes defined:
+//
+//      nsFilePath, nsFileURL, nsFileSpec, nsPersistentFileDescriptor
+//      nsDirectoryIterator. Oh, and a convenience class nsAutoCString.
+//
+//  Q.  How should I represent files at run time?
+//  A.  Use nsFileSpec.  Using char* will lose information on some platforms.
+//
+//  Q.  Then what are nsFilePath and nsFileURL for?
+//  A.  Only when you need a char* parameter for legacy code.
+//
+//  Q.  How should I represent files in a persistent way (eg, in a disk file)?
+//  A.  Use nsPersistentFileDescriptor.  Convert to and from nsFileSpec at run time.
+//
+//  This suite provides the following services:
+//
+//      1.  Encapsulates all platform-specific file details, so that files can be
+//          described correctly without any platform #ifdefs
+//
+//      2.  Type safety.  This will fix the problems that used to occur because people
+//          confused file paths.  They used to use const char*, which could mean three
+//          or four different things.  Bugs were introduced as people coded, right up
+//          to the moment Communicator 4.5 shipped.
+//
+//      3.  Used in conjunction with nsFileStream.h (q.v.), this supports all the power
+//          and readability of the ansi stream syntax.
+//
+//          Basic example:
+//
+//              nsFilePath myPath("/Development/iotest.txt");
+//

+//      4.  Handy methods for manipulating file specifiers safely, e.g. MakeUnique(),
+//          SetLeafName(), Exists().
+//
+//      5.  Easy cross-conversion.
+//
+//          Examples:
+//
+//              Initialize a URL from a string
+//
+//                  nsFileURL fileURL("file:///Development/MPW/MPW%20Shell");
+//
+//              Initialize a Unix-style path from a URL
+//
+//                  nsFilePath filePath(fileURL);
+//
+//              Initialize a file spec from a URL
+//
+//                  nsFileSpec fileSpec(fileURL);
+//
+//              Make the spec unique.
+//
+//                  fileSpec.MakeUnique();
+//
+//              Assign the spec to a URL (causing conversion)
+//
+//                  fileURL = fileSpec;
+//
+//              Assign a unix path using a string
+//
+//                  filePath = "/Development/MPW/SysErrs.err";
+//
+//              Assign to a file spec using a unix path (causing conversion).
+//
+//                  fileSpec = filePath;
+//
+//              Make this unique.
+//
+//                  fileSpec.MakeUnique();
+//
+//      6.  Fixes a bug that have been there for a long time, and
+//          is inevitable if you use NSPR alone, where files are described as paths.
+//
+//          The problem affects platforms (Macintosh) in which a path does not fully
+//          specify a file, because two volumes can have the same name.  This
+//          is solved by holding a "private" native file spec inside the
+//          nsFilePath and nsFileURL classes, which is used when appropriate.
