Hi All,
I noticed that InetAddress.getLocalHost() uses cache to improve the
performance. However the default implementation is caching local host
within 5 seconds.
From the spec, networkaddress.cache.ttl should be used to control the
cache behaviour and I think it is a better solution.
For example, if the networkaddress.cache.ttl is set to -1 which means
always cache the local host then we can avoid unnecessary operations on
getAddressesFromNameService to improve the performance.
I have made a patch for this solution, so anyone would like to take a look?
