+
+/*
+    Documentation:
+
+    Some sites have a set of static files that are really busy, and
+    change infrequently (or even on a regular schedule). Save time
+    by caching open handles to these files. This module, unlike
+    mod_mmap_static, caches open file handles, not file content.
+    On systems (like Windows) with heavy system call overhead and
+    that have an efficient sendfile implementation, caching file handles
+    offers several advantages over caching content. First, the file system
+    can manage the memory, allowing infrequently hit cached files to
+    be paged out. Second, since caching open handles does not consume
+    significant resources, it will be possible to enable an AutoLoadCache
+    feature where static files are dynamically loaded in the cache
+    as the server runs. On systems that have file change notification,
+    this module can be enhanced to automatically garbage collect
+    cached files that change on disk.
+
+    This module should work on Unix systems that have sendfile. Place
+    cachefile directives into your configuration to direct files to
+    be cached.
+
+        cachefile /path/to/file1
+        cachefile /path/to/file2
+        ...
+
+    These files are only cached when the server is restarted, so if you
+    change the list, or if the files are changed, then you'll need to
+    restart the server.
+
+    To reiterate that point:  if the files are modified *in place*
+    without restarting the server you may end up serving requests that
+    are completely bogus.  You should update files by unlinking the old
+    copy and putting a new copy in place.
+
+    There's no such thing as inheriting these files across vhosts or
+    whatever... place the directives in the main server only.
+
+    Known problems:
+
+    Don't use Alias or RewriteRule to move these files around...  unless
+    you feel like paying for an extra stat() on each request.  This is
+    a deficiency in the Apache API that will hopefully be solved some day.
+    The file will be served out of the file handle cache, but there will be
+    an extra stat() that's a waste.
