Failover with one CSS and two webservers?

Hi there,

I have another question about failover.

When you have only two webservers, how can you do failover. When one service has reached it's threshold, it should failover to the next available services (depending on your config). But if you only have two webservers running webservice port 80, and you have therefore configured two services on the CSS - say http_web1 and http_web2 -

then shouldn't failover give more problems?

I mean, when http_web1 reaches it's threshold, it should failover all of it's connections to the remaining services (http_web2) but that should also completely trash http-web2, right?

And then web2 should try to failover to web1 but finds web1 unavailable. I've set this up in the lab but apparently it does work. I just want to know why it works, can't figure it out

thanx,

Radboud

check exactly what's happening.

Your active connections will most probably stay with the first server after *failover* because the CSS usually do not touch active connections whatever happens.

So only new connections are redirected to the new server, so this one is far beyond the limit and can accept the new connections easily.

Gilles.
