By default, any time a stability manager is set up, as a way to safeguard towards DNS spoofing attacks, the results of optimistic host name resolutions are cached permanently. Any time a protection manager will not be installed, the default habits is always to cache entries for just a finite (implementation dependent) stretch of time. The result of unsuccessful host title resolution is cached for a very limited time period (ten seconds) to improve effectiveness. In the event the default conduct is not really wanted, then a Java protection assets can be set to another Time-to-Reside (TTL) worth for favourable caching. Similarly, a process admin can configure another destructive caching TTL price when needed. Two Java security Qualities Management the TTL values employed for beneficial and destructive host identify resolution caching: networkaddress.cache.ttl
