So far we have learned the meaning of different parameters used with the
cache_dir directive. Let's see an example of the cache directory
/squid_cache/ with 50GB of free space:
cache_dir aufs /squid_cache/ 51200 32 512

/squid_cache/ with a 50 GB free disk space as a cache directory to cache web documents on the hard disk. Following the previous instructions, we can ...
