# Cache

The views use by default a cache system.

When loading a view, a file titled tmp_{fileDirectory}.php will be created in the cache folder if it doesn't exists already.

So the view will be loader from that file and any change made to the original file will not be displayed until the cache file expires or is deleted manually.

You can perfectly refresh the cache deleting the cache folder content.

If you want to force a view to don't use the cache system, you can pass a false value to the loader view method as the third parameter.

$this->load->view('home', $data, false);

This will force that view to don't use the cache system, keep in mind that the loading time could increase due to this.

The default life time for a cache file is One week, it is specified as a constant in the system/Core/Cache.php file, you can change it if you want.
