Load balancing with nginx using ip_hash;


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 {

Today I noticed that one subdomain was going to and another
one to 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.
