$cache_dir

This is the name of the directory where template caches are stored. By default this is "./cache", meaning that Smarty will look for the cache directory in the same directory as the executing php script. This directory must be writeable by the web server (see install). You can also use your own custom cache handler function to control cache files, which will ignore this setting. See also $use_sub_dirs.
