“ /cache “ is your cache directory and 2000 is its space size on
disk(2000 MB = 2 GB) set this value whatever you want cache size) ##uncomments the below lines if you want to make log files cache_access_log /???/???/???/access.log cache_store_log /???/???/???/store.log cache_log /???/ ???/????/ cache_replacement_policy GDSF #
