Thanks Paul,

It would be nice to have this piece of code in
org.apache.nutch.fetcher.Fetcher


private static final int DNS_CACHE_TTL_MINUTES =
    NutchConf.get().getFloat("dns.cache.ttl.minutes", 100);


static {
  java.security.Security.setProperty("networkaddress.cache.ttl" , 
    DNS_CACHE_TTL_MINUTES*60);
}

(may be smth better...)



>> java.security.Security.setProperty("networkaddress.cache.ttl" , 
>> "10000");

>I had to look up what the units are for this since your message was
possibly ambiguous.

>The units are in seconds; 10000 is about 150 minutes, the default is -1.

>When working with Weblogic a few years ago, I noticed that they included
the units in the property names.  For example:

>     something.timeoutMsec  or  something.timeoutSec

>similarly,

>     final static int SOMETHING_TIMEOUT_MSEC = 2000;

>I encourage this practice.
