This is the name of the directory where template caches are
stored. By default this is
./cache, meaning that
Smarty will look for the
in the same directory as the executing php script.
This directory must
be writeable by the web server,
see install for more info.
This setting must be either a relative or absolute path. include_path is not used for writing files.
It is not recommended to put this directory under the web server document root.
