How reload Twig cache in Symfony 2

Question

I have a application which is developed in PHP using the Symfony 2 framework. I have changed a HTML file, but the change is not reflecting when I refresh the page.

When creating a new Twig_Environment instance, you can pass an array of options as the constructor second argument. One of them is auto_reload. When developing with Twig, it's useful to recompile the template whenever the source code changes. If you don't provide a value for the auto_reload option, it will be determined automatically based on the debug value.

Set auto_reload to be true:

$twig = new Twig_Environment($loader, array('auto_reload' => true));
