FinalBSD, Ace, I was hoping someone would add that feature. Just tested it and it works perfectly.
My tests were: 1) check index.html for value "mytesttext" - result - OK site up - CORRECT (text is present on my page) 2) check index.html for value "not found" - result - site down - CORRECT (text not present on my page) 3) check doesntexist.html for value "not found" - result - site down - CORRECT (even though text is present on apache error page) Ldirectord / LVS also has a seperate interval time for http health checks (so you can make it longer), and also the option to do x TCP checks followed by 1 HTTP/grep check (to lower the impact of health checks on the cluster) These are just ideas for improvements but core feature is very useful, thanks again. 2009/2/18 匡萃彪 <[email protected]> > > Hi folks, > I wrote a patch and add two new features for haproxy(1.3.15.7) yesterday . > > 1.
