On first request to a given URL whole html code of a page is being stored in 
the SQLite database. On next requests to the same page WordPress core will 
not be loaded at all but the content of a page will be retrieved from the 
the SQLite storage therefore duration of PHP execution decreases in dozen 
of times.
Many sites on the same webserver may use common SQLite storage. 
Compatible with WordPress Multisite. Requires PHP SQLite PDO.
In comparison with plugins generating static html pages this plugin does not 
create multiple directories and html files but stores all generated pages 
in one file. Moreover, many wordpress sites on the same webserver may use 
common SQLite storage. Keeps 404, 301, 302, 304 HTTP statuses, optionally 
supports ETag, Expires, Content-Length, Content-Type (with charset) headers.
<h4>As the cache script doesn’t load the WordPress core where does it save it’s settings?</h4>
To get the plugin working you need to define the SQLite storage location in 
the <code>index.php</code> of the wordpress installation directory (note, not in wp-config.php 
but index.php). Besides of the SQLite file, this directory contains general 
settings file (compression setting) and a subfolder for per domain settings. 
In the admin area (plugin setting page) and to remember after deactivation where 
the cache located, <code>litecache_path</code> WordPress option is used.
<h4>How the plugin handles URLs with and without `www.` prefix?</h4>
The presence of <code>www.</code> prefix is defined in <code>Settings</code> – <code>General</code>. 
The plugin stores <code>with_www</code> parameter in <code>domains/yourdomain.ini</code> file in the 
cache directory and redirects requests correspondingly; these redirects are 
being processed before cache usage.
<h4>Is it WordPress Multisite compatible?</h4>
Yes, but for subdomains mode only (blogname.example.com), not for 
example.com/blogname. A superadmin of a multisite network has access to 
the first setting form (cache location), blog admins have access to the 
second form and purge form.

SQLite Cache

Provides SQLite cache storage that applied before WordPress core load. Doesn't create multiple html files but stores all pages in one file.
