-<h1>Output Class</h1>
-
-<p>The Output class is a small class with one main function: To send the finalized web page to the requesting browser. It is
-also responsible for <a href="../general/caching.html">caching</a> your web pages, if you use that feature.</p>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-<p>Under normal circumstances you won't even notice the Output class since it works transparently without your intervention.
-For example, when you use the <a href="../libraries/loader.html">Loader</a> class to load a view file, it's automatically
-passed to the Output class, which will be called automatically by CodeIgniter at the end of system execution.
-It is possible, however, for you to manually intervene with the output if you need to, using either of the two following functions:</p>
-
-<h2>$this->output->set_output();</h2>
-
-<p>Permits you to manually set the final output string. Usage example:</p>
-
-<code>$this->output->set_output($data);</code>
-
-<p><strong>Important:</strong> If you do set your output manually, it must be the last thing done in the function you call it from.
-For example, if you build a page in one of your controller functions, don't set the output until the end.</p>
-
-
-<h2>$this->output->get_output();</h2>
-
-<p>Permits you to manually retrieve any output that has been sent for storage in the output class. Usage example:</p>
-<code>$string = $this->output->get_output();</code>
-
-<p>Note that data will only be retrievable from this function if it has been previously sent to the output class by one of the
-CodeIgniter functions like <var>$this->load->view()</var>.</p>
-
-
-<h2>$this->output->set_header();</h2>
-
-<p>Permits you to manually set server headers, which the output class will send for you when outputting the final rendered display. Example:</p>
-
-<code>
-$this->output->set_header("HTTP/1.0 200 OK");<br />
-$this->output->set_header("HTTP/1.1 200 OK");<br />
-$this->output->set_header('Last-Modified: '.gmdate('D, d M Y H:i:s', $last_update).' GMT');<br />
-$this->output->set_header("Cache-Control: no-store, no-cache, must-revalidate");<br />
-$this->output->set_header("Cache-Control: post-check=0, pre-check=0");<br />
-$this->output->set_header("Pragma: no-cache"); </code>
-
-
-<h2>$this->output->set_status_header();</h2>
-
-<p>Permits you to manually set a server status header. Example:</p>
-
-<code>$this->output->set_status_header('401');<br />
-// Sets the header as: Unauthorized</code>
-
-<p><a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html">See here</a> for a full list of headers.</p>
-
-<h2>$this->output->enable_profiler();</h2>
-
-<p>Permits you to enable/disable the <a href="../general/profiling.html">Profiler</a>, which will display benchmark and other data
-at the bottom of your pages for debugging and optimization purposes.</p>
-
-<p>To enable the profiler place the following function anywhere within your <a href="../general/controllers.html">Controller</a> functions:</p>
-<code>$this->output->enable_profiler(TRUE);</code>
-
-<p>When enabled a report will be generated and inserted at the bottom of your pages.</p>
-
-<p>To disable the profiler you will use:</p>
-<code>$this->output->enable_profiler(FALSE);</code>
-
-
-<h2>$this->output->cache();</h2>
-<p>The CodeIgniter output library also controls caching. For more information, please see the <a href="../general/caching.html">caching documentation</a>.</p>
