# 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 or the folder itself.

If you want to force a view to don't use the cache system, you can pass a false value to the render method of the Wolff\Core\View class as the third parameter.

View::render('home', $data, false);

That 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.
