Thank you! As long as after a timeout it detects the server as down this is good enough. Just making sure so that I don't have 1/3 of the connections failing before someone puts the backend in MX mode.

Only TCP profiles My findings are documented on my site at: http://www.talking-it.com/category/zlb-2/farmguardian/ Thanks Nick >>> "Andreas M.

Is there a way for Zen to detect whether a host is down and then take it out of the cluster? I.e. if one backend server were to fail, could Zen stop redirecting traffic there without manual intervention (i.e. maintenance mode). Kinda like farmguardian for TCP. It would be alright if it took Zen one "time out" on one connection rather than actively checking. -Andy Transform Medical Group (CS) Limited.
