+<h2>Processing Output</h2>
+
+<p>Code Igniter has an output class that takes care of sending your final rendered data to the web browser automatically.  More information on this can be found in the
+<a href="views.html">Views</a> and <a href="../libraries/output.html">Output class</a> pages.  In some cases, however, you might want to control
+how the output gets sent to the browser, or you might want to post process the finalized data in some way.  Code Igniter permits you to 
+add a function named <dfn>_output()</dfn> to your controller that will receive the finalized output data.
+
+<p class="important"><strong>Important:</strong>&nbsp; If your controller contains a function named <kbd>_output()</kbd>, it will <strong>always</strong> 
+be called by the output class instead of echoing the finalized data directly. The first parameter of the function will contain the finalized output.</p>
+
+<p>Here is an example:</p>
+
+<code>
+function _output($output)<br />
+{<br />
+&nbsp;&nbsp;&nbsp;&nbsp;echo $output;<br />
+}</code>
+
+<p>Please note that your <dfn>_output()</dfn> function will receive the data in its finalized form - including rendered benchmark and memory usage data, 
+so if you are using this feature the page execution timer might not be perfectly accurate.</p>

 underscore as the name prefix and it will not be served via a URL request. For example, if you were to have a function like this:</p>
