Any way to make Java honor the DNS Caching Timeout (TTL)?

We use GSLB for geo-distribution and load-balancing. Each service is assigned a fixed domain name. Through some DNS magic, the domain name is resolved into an IP that's closest to the server with least load. For the load-balancing to work, the application server needs to honor the TTL from DNS response and to resolve the domain name agai...

Load balancing: DNS round robin in front of hardware load balancers. How to share stickiness?

Hi, DNS Round Robin (DRR) permits to do cheap load balancing (distribution is a better term). It has the pro of permitting infinite horizontal scaling. The con is that if one of the web servers goes down, some clients continue to use the broken IP for minutes (min TTL 300s) or more, even if the DNS implements fail-over. An Hardware Loa...
