<p>FlexiCache is a fast, full-featured and flexible caching system which will improve the performance and availability of any WordPress site.</p>
<p>It is highly configurable to allow unlimited caching rules – expiring different pages at different times, not caching some pages at all, caching multiple versions of the same page depending on browser, language, and so on.</p>
<p>FlexiCache will also work straight out of the box without any need for complex configuration.</p>
<h4>Features</h4>
<ul>
<li>Extensively configurable using user-defined conditions</li>
<li>Handling of high-traffic periods where multiple clients may simultaneously request uncached or expired items</li>
<li>Standalone mode which bypasses WordPress and third-party theme and plugin code to serve cached pages faster</li>
<li>Choice of storage engines: Filesystem, Memcache and SQLite</li>
<li>Pre-caching functionality to cache new versions of pages before the existing ones expire</li>
<li>SQLite indexing of Filesystem and Memcache stores to speed up removing specific items from the cache (automatically enabled if SQLite is available)</li>
<li>Sends appropriate HTTP cache headers to the requesting client</li>
<li>Serves files in compressed formats accepted by the requesting client</li>
<li>Compatible with WordPress MU</li>
</ul>
<h3>Upgrading FlexiCache</h3>
<p>FlexiCache stores config and cache data within the plugin directory (see plugin documentation in versions 1.2.4.2 onwards for the reason why).</p>
<p>If you upgrade the plugin using WordPress’s built-in upgrade process, the entire plugin directory will be replaced, including your config and cache data.</p>
<p>To preserve these, take a copy of the “plugins/FlexiCache/_data” directory before upgrading, and then copy it back after the upgrade is complete.</p>
<p>If you upgrade directly via SVN, this should not be required, since only the files under version control will be updated.</p>
<h3>Deactivating FlexiCache</h3>
<p>FlexiCache can be disabled via the admin interface as with any plugin, however if you are running in Standalone mode, you should remove the .htaccess modifications before deactivating the plugin.</p>
<p>For a standard WordPress install, this modification can be done via the admin interface, however it is recommended that you make this change manually, especially if using WordPress MU, where multiple sites may share the same .htaccess file.</p>
<p>Please see the documentation supplied with the plugin (accessible via WordPress’s admin interface) for more information.</p>
