+<h1>Caching Driver</h1>
+
+<p>CodeIgniter features wrappers around some of the most popular forms of fast and dynamic caching.  All but file-based caching require specific server requirements, and a Fatal Exception will be thrown if server requirements are not met.</p>

+</ul>
+
+<h2 id="example_usage">Example Usage</h2>
+
+<p>The following example will load the cache driver, specify <a href="#apc" title="APC">APC</a> as the driver to use, and fall back to file-based caching if APC is not available in the hosting environment.</p>
+
+<code>
+$this->load->driver('cache', array('adapter' => 'apc', 'backup' => 'file'));<br />
+<br />
+if ( ! $foo = $this->cache->get('foo'))<br />
+{<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;echo 'Saving to the cache!&lt;br />';<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$foo = 'foobarbaz!';<br />
+<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// Save into the cache for 5 minutes<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$this->cache->save('foo', $foo, 300);<br />
+}<br />
+<br />
+echo $foo;
+</code>
+
+<h1 id="function_reference">Function Reference</h1>
+
+<h2>is_supported(<var>driver</var>['string'])</h2>
+
+<p>This function is automatically called when accessing drivers via <samp>$this->cache->get()</samp>.  However, if the individual drivers are used, make sure to call this function to ensure the driver is supported in the hosting environment.</p>
+
+<code>
+if ($this->cache->apc->is_supported())<br />
+{<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;if ($data = $this->cache->apc->get('my_cache'))<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;{<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;// do things.<br />
+&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}<br />
+}
+</code>
+
+<h2>get(<var>id</var>['string'])</h2>
+
+<p>This function will attempt to fetch an item from the cache store.  If the item does not exist, the function will return <samp>FALSE</samp>.</p>
+<code>$foo = $this->cache->get('my_cached_item');</code>
+
+<h2>save(<var>id</var>['string'], <var>data</var>['mixed'], <var>ttl</var>['int'])</h2>
+
+<p>This function will save an item to the cache store.  If saving fails, the function will return <samp>FALSE</samp>.</p>
+<p>The optional third parameter (Time To Live) defaults to 60 seconds.</p>
+<code>$this->cache->save('cache_item_id', 'data_to_cache');</code>
+
+<h2>delete(<var>id</var>['string'])</h2>
+
+<p>This function will delete a specific item from the cache store.  If item deletion fails, the function will return <samp>FALSE</samp>.</p>
+<code>$this->cache->delete('cache_item_id');</code>
+
+<h2>clean()</h2>
+
+<p>This function will 'clean' the entire cache.  If the deletion of the cache files fails, the function will return <samp>FALSE</samp>.</p>
+
+<code>$this->cache->clean();</code>
+
+<h2>cache_info()</h2>
+
+<p>This function will return information on the entire cache.</p>
+
+<code>var_dump($this->cache->cache_info());</code>
+
+<h2>get_metadata(<var>id</var>['string'])</h2>
+
+<p>This function will return detailed information on a specific item in the cache.</p>
+
+<code>var_dump($this->cache->get_metadata('my_cached_item'));</code>
+
+<h1>Drivers</h1>
+
+<h2 id="apc">Alternative PHP Cache (APC) Caching</h2>
+
+<p>All of the functions listed above can be accessed without passing a specific adapter to the driver loader as follows:</p>
+<code>$this->load->driver('cache');<br />
+	$this->cache->apc->save('foo', 'bar', 10);</code>
+<p>For more information on APC, please see <a href="http://php.net/apc">http://php.net/apc</a></p>
+
+<h2 id="file">File-based Caching</h2>
+
+<p>Unlike caching from the Output Class, the driver file-based caching allows for pieces of view files to be cached.  Use this with care, and make sure to benchmark your application, as a point can come where disk I/O will negate positive gains by caching.</p>
+
+<p>All of the functions listed above can be accessed without passing a specific adapter to the driver loader as follows:</p>
+<code>$this->load->driver('cache');<br />
+	$this->cache->file->save('foo', 'bar', 10);</code>
+
+<h2 id="memcached">Memcached Caching</h2>
+
+<p>Multiple Memcached servers can be specified in the memcached.php configuration file, located in the <samp>application/config/</samp> directory.
+
+<p>All of the functions listed above can be accessed without passing a specific adapter to the driver loader as follows:</p>
+<code>$this->load->driver('cache');<br />
+	$this->cache->memcached->save('foo', 'bar', 10);</code>
+
+<p>For more information on Memcached, please see <a href="http://php.net/memcached">http://php.net/memcached</a></p>
+
+<h2 id="dummy">Dummy Cache</h2>
+
+<p>This is a caching backend that will always 'miss.'  It stores no data, but lets you keep your caching code in place in environments that don't support your chosen cache.</p>

+<h2>Environments</h2>
+
+<p>You can set the environment of you application and load config items depending on the current environment. It also disables PHP from displaying errors in environments other than development. To set your environment, open <strong>index.php</strong>, located at the root and change the <var>ENVIRONMENT</var> constant. By default, there is support for a development, test and production environment.</p>
+	
+<code>
+define('<var>ENVIRONMENT</var>', '<var>development</var>');	
+</code>
+
+<p>To make a config file environment-aware, copy the file from <samp>application/config/</samp> to <samp>application/config/development/</samp>, depending on the environment the config file belongs to. You can place the following configuration files in environment folders:</p>
+	
+<ul>
+<li>Default config files</li>
+<li>Database config files</li>
+<li>Custom config files</li>
+</ul>
+
+<p><strong>Note:</strong> CodeIgniter always tries to load the config file for the current environment first. If the file does not exist, the global config file (i.e. <samp>application/config/</samp>) is loaded. This means you are not obligated to place <strong>all</strong> your config files (but rather the files that change per environment) in an environment folder.</p>

 <p>For site-wide cookies regardless of how your site is requested, add your URL to the <strong>domain</strong> starting with a period, like this:  .your-domain.com</p>
 <p>The path is usually not needed since the function sets a root path.</p>
 <p>The prefix is only needed if you need to avoid name collisions with other identically named cookies for your server.</p>
