<p>The CacheLocalFD directive is used to specify the names of ASCII/BINARY
stream files whose descriptors you want to cache at server startup. The file
is opened (share read) and remains open while the server is active. The configuration
file can contain multiple directive occurrences. Include a separate directive
for each file that you want to remain open. By keeping your most frequently
requested files/images opened at server startup, you can improve your server's
response time for those files. For example, if you open your server's welcome
page files at startup, the server can handle requests for the page much more
quickly than if it had to open the files each time they are requested. </p>
<dl class="block"><dt class="dlterm"><strong>Parameter</strong>: <em>filename </em></dt>
<dd><ul><li>The <em>filename</em> parameter specifies the names of ASCII/BINARY stream
files whose descriptors are cached at server startup.</li>
</ul>
</dd>
</dl>
<p>The advantage of using CacheLocalFD directive over CacheLocalFile is that
it does not cache the content of the file, and therefore does not allocate
a large amount of memory, yet provides similar performance. The disadvantage
of using CacheLocalFD directive over CacheLocalFile is that it only caches
the file descriptors of ASCII/BINARY stream files and it keeps the file open
(share read) while the server is active.</p>
<p>The LiveLocalCache directive setting does not apply to this directive and
if a cached file is updated, the cached entity is discarded and the updated
file is served from the file system. If a cached file is modified while at
the same time being served, the content of the response body is unpredictable.</p>
<div class="note"><span class="notetitle">Note:</span> You can use an asterisk ('*') as a wildcard character on the file names
(for example, CacheLocalFD *.gif). File name matching is not recursive through
subdirectories. The server will only cache files in the specified directory.

<p>The CacheLocalFileMmap directive is used to specify the names of files
that you want to map to the server's memory each time that you start the server.
This directive is similar to the CacheLocalFile directive. Whereas CacheLocalFile
allocates storage and copies (read/write) the content of the file to the allocated
storage, CacheLocalFileMmap maps the file content to the process storage space
without actually allocating storage.</p>
<p>The LiveLocalCache directive setting does not apply to this directive and
if a cached file is updated, the cached entity is discarded and the updated
file is served from the file system. If a cached file is modified while at
the same time being served, the content of the response body is unpredictable. </p>

</ul>
</dd>
</dl>
<p>You can have multiple occurrences of this directive in the configuration
file. Include a separate directive for each file that you want to load into
memory. By keeping your most frequently requested files mapped in the server's
address space, you can improve your server's response time for those files.
For example, if you map your server's welcome at startup, the server can handle
requests for the page much more quickly than if it had to read the file from
the file system. </p>
<div class="note"><span class="notetitle">Note:</span> You can use an asterisk (*) as a wildcard character on the file names
(for example, CacheLocalFileMmap *.html). File name matching is not recursive
through subdirectories. The server will only cache files in the specified
directory. No files in subdirectories are affected. The relative/absolute
path rules apply to this directive, meaning that a path that begins without
a leading (/) character is considered to be absolute. Otherwise, the path
is based on the server's document root.</div>

</div>
<p> The CacheLocalFilePublic directive is used to specify the names of files
that you want to load into the server's memory each time that you start the
server. The files cached here are files that are served without any server
authentication. This directive is used by SSL sites which have pages that
are publicly available. This simulates the FRCA function completed by the
server for non-SSL publicly available files. You can have multiple occurrences
of this directive in the configuration file. Include a separate directive
for each file that you want to load into memory. By keeping your most frequently
requested public files loaded in the server's memory, you can improve your
server's response time for those files. For example, if you load your server's
welcome page into memory at startup, the server can handle requests for the
page much more quickly than if it had to read the file from the file system.</p>
<p><strong>Note:</strong> You can use an asterisk (''*'') as a wildcard character on
the file names, (for example, CacheLocalFile *.html).</p>
<p>File name matching is not recursive through subdirectories. The server
only caches files in the specified directory. No files in subdirectories
are affected. There is no authentication or authorization done before any
files in this cache are served. </p>

<p>The CacheLocalFileSizeLimit directive is used to specify, in bytes, the
largest file that will be placed in the local memory cache. A file larger
than the value specified for CacheLocalFileSizeLimit will not be placed in
the cache. This prevents the cache from being filled by only a small number
of very large files. The upper limit for this directive is capped at 16,000,000.

<p>The LiveLocalCache directive is used to specify if the cache is updated
when a cached file is modified. Set this directive to "on" if you want users,
requesting a cached file, to receive the file with the latest updates. Setting
this directive to "off" is the optimum setting for performance. When LiveLocalCache
directive is set to "on", before responding to a request for a file that is
stored in memory, the server checks to see if the file has changed since the
server was started. If the file has changed, the server responds to this request
with the updated file. The server then deletes the older file version from
memory. Restart the server to load the new file into memory.</p>
