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.

If you are using opcache/other similar caching, deleting twig's cache folder won't refresh templates as twig cache consist of only .php files. You need to delete twig's cache folder + execute php file which contains:

opcache_reset();
