Set the maximum number of cache entries

The gsk-crl-cache-size stanza entry specifies the maximum number of entries in the GSKit CRL cache. Each entry represents an entire CRL for a particular certificate authority. The default setting is "0". A value greater than "0" is required to activate the cache.

Note: CRL entries can use a large amount of memory. Therefore, try to specify the minimal value for the gsk-crl-cache-size.
