Specifies the directory for holding cached objects. Currently, LiteSpeed Cache stores each object in its own file. The filename is a hash of the object key. Multiple levels of directories will be created in order to avoid holding too many files in one directory. This value must be set at the Server level in order to enable cache. Virtual Host level settings will override Server level settings.
path
Assign a dedicated disk or disk array as the cache storage. RAID0 is recommended.
It is recommended to set a different cache storage path for each Virtual Host to prevent purge all requests from affecting other Virtual Hosts.

The maximum age of a cached file before the server will attempt to physically remove it. This removal operation will occur once per day to prevent cache storage from growing too large. Minimum setting is 60 minutes.
Integer number
Set this value to a time greater than your longest TTL to help prevent the removal of still valid cache files.
The maximum number of minutes a cached file will remain in cache storage without a cache hit before being physically removed by the server. Set to 0 to disable this feature.

A list of URL segments where any URL containing these listed segments will not be cached. String matching is used. Regular expressions are not supported. Can be set at the server or virtual host level. URL segments listed at the server level are inherited by all virtual hosts and added to their Do-Not-Cache URL lists.
You can add comments by starting a line with "#".
A comma-separated list of domains that will not be cached.
Comma-separated list. Domain names are case insensitive and the leading "www." should be removed. The wildcard characters "*" and "?" are allowed. "?" only replaces one character. "*" replaces any number of characters. For example, "*.mydomain.com" will match all subdomains of mydomain.com. Duplicate domain names are not allowed.
