I am looking to implement NGINX as a reverse proxy cache for a number  
of sites, there are 6 fairly busy sites between 4 webservers. I can  
find plenty of online assistance in configuring NGINX to reverse cache  
a single site from a single origin. I appear to be struggling to find  
how to configure a single NGINX installation to reverse cache multiple  
sites from multiple origins.

Could anyone point me in the right direction on this, or am I overly  
complicating a simple config?

Thanks in advance,

John

Just define multiple servers and configure them. See here for  
details:

Something like this should work:

```
proxy_cache_path /path/to/cache keys_zone=one:10m;

server {
    listen ...
    server_name site1.example.com;

    location / {
        proxy_pass http://site1.backend;
        proxy_cache one;
    }
}

server {
    listen ...
    server_name site2.example.com;

    location / {
        proxy_pass http://site2.backend;
        proxy_cache one;
    }
}

```
