Hello,

I've experienced strange behavior - I have website with many subdomains and I have nginx set up as load balancer and proxy to apache.

each subdomain is using

proxy_pass http://apaches;

While upstream apaches is defined as follows:

upstream apaches {
ip_hash;
server 127.0.0.1:8044;
server 10.0.0.1:8044;
}


Today I noticed that one subdomain was going to 127.0.0.1 and another one to 10.0.0.1. I always thought nginx calculates the ip_hash centrally and then it does not matter in how many virtualhosts are there, it always points the ip to the same upstream.

I'm using nginx/0.8.33.

Thank you.
