Upstream "Sticky Connections?"

July 18, 2012 09:51AM
Hello Everyone,

We are currently using Nginx 1.2.1 to terminate SSL and to load balance between two JBoss servers.

Here is my upstream block:


upstream jboss_servers {
ip_hash;
server 192.168.1.100:8080;
server 192.168.1.101:8080;
}

The issue we're having is such -- When a user is connected to Nginx, Nginx will proxy the connection to one of the two backend servers, for example 192.168.1.100. If we take that server offline (by stopping JBoss) the user is directed to the 192.168.1.101 server and their session is broken, requiring them to login again. We understand and accept this.

However, when server 192.168.1.100 is brought back online, Nginx is then redirecting their session back to that server, breaking their session and requiring them to login yet again.

Is there a directive I can use to prevent this behavior? I've seen this referred to in other places as sticky sessions, does Nginx support a similar method?
