Haproxy sounds like the perfect tool for it. I know of many companies that use haproxy simply because they're fronting an ever changing set of EC2 instances that go up and down all the time. Haproxy's reload is very clean; it does a very good job of transitioning ownership of the bound socket between old and new PID's without dropping incoming requests while existing requests continue to serve out of the old PID. At my last company, I had a job that wrote new config files and reloaded haproxy automatically at regular intervals. > > Thanks, > Corin > >
