2014-11-26 Thread Ulrich.Herbst
Maybe this should be a admin-configurable solution. Something like: Apache proxy checks backend server port 4711 and expects load data in a defined format. And we can configure, how often apache checks this backend server (maybe just every 10 seconds and not with every request...). And everyone
