nginx 1.2.7 on CentOS 6.3. Reverse-proxy with two upstream servers.  
One  
server should be default, the other should only be used when called from  
a  
link on a specific web server.

I have the reverse proxy working fine for the default upstream, but not  
quite right on the second, site-specific upstream. Ignoring that I am  
also  
rewriting for http to force https (yeah, I know, it’s discouraged to go  
encrypted between the nginx proxy and its upstreams, but it’s a  
corporate  
security thing) I am using a two server block configuration, one server  
name  
for the default and another for the site-specific server. The  
site-specific  
server will link to the default server URL but should rewrite to the  
site-specific upstream’s proxy’s URL.

It seems to work - not sure if it gets stuck in the proxy or on the  
upstream  
for the site-specific setup -, but it was suggested that a single  
server,  
selecting between upstream servers, would be preferable. I would like  
to  
know how that would be configured - just a quick overview or link to a  
documentation page would help a lot.

If I can throw together a quick test of a single-server-block  
reverse-proxy  
config with multiple upstreams which are selected based on calling  
server, I  
could test to see if it’s my multi-server-block setup or a problem on  
the  
upstream.

Thanks!

Jim.

Normal nginx aproach is to use distinct server blocks for servers  
with different configuration.
