+.B pcacheValidate { TRUE | FALSE }
+Check whether the results of a query being cached can actually be returned
+from the cache by the proxy DSA. When enabled, the entries being returned
+while caching the results of a query are checked to ensure consistency
+with the schema known to the proxy DSA. In case of failure, the query
+is not cached. By default, the check is off.
+
+.TP
+.B pcacheOffline { TRUE | FALSE }
+Set the cache to offline mode. While offline, the consistency checker
+will be stopped and no expirations will occur. This allows the cache
+contents to be used indefinitely while the proxy is cut off from network
+access to the remote DSA. The default is FALSE, i.e. consistency
+checks and expirations will be performed.
+
+.TP
+.B pcachePersist { TRUE | FALSE }
+Specify whether the cached queries should be saved across restarts
+of the caching proxy, to provide hot startup of the cache. Only non-expired
+queries are reloaded. The default is FALSE.
+
+.BR CAVEAT :
+of course, the configuration of the proxy cache must not change
+across restarts; the pcache overlay does not perform any consistency
+checks in this sense.
+In detail, this option should be disabled unless the existing
+.B pcacheAttrset
+and
+.B pcacheTemplate
+directives are not changed neither in order nor in contents.
+If new sets and templates are added, or if other details of the pcache
+overlay configuration changed, this feature should not be affected.
+
+.TP
+.B pcacheTemplate <template_string> <attrset_index> <ttl> [<negttl> [<limitttl> [<ttr>]]]
+Specifies a cacheable template and "time to live" <ttl> of queries
