Distinct upstream servers by name

January 12, 2011 04:26PM

I want to proxy 2 apache vhosts.
Both vhosts running on apache default port: 8080 and both are resolved through /etc/hosts

upstream ultimabex_upstream{
server ultimabex.va:8080;
server ultimabex.vb:8080;

The issue is how to send correct Host header to apache so it will find vhost in his vhosts.conf
and serve it accordingly.

Used custom LogFormat in apache to catch ServerName(%v),
Canonical ServerName(%V) ans Host(%h) headers sent by nginx.
Setting Host in nginx is altering Canonical ServerName(%V) in apache headers.

proxy_set_header Host $upstream_http_host - resulting in in apache logs
proxy_set_header Host $upstream_http_hostname - resulting in first found apache vhost

It works great when i set Host manually, like:
proxy_set_header Host "ultimabex.va"
proxy_set_header Host "ultimabex.vb"

Any way to set it automatically?

Thank you.
