upstream_phpapache.conf

### Upstream configuration for Apache functioning has a PHP handler.

## Add as many servers as needed.
## Cf. http://wiki.nginx.org/HttpUpstreamModule.
## Note that this configuration assumes by default that keepalive
## upstream connections are supported and that you have a Nginx
## version with the fair load balancer.

upstream phpapache {
    ## Use the least connection algorithm for load balancing. This
    ## algorithm was introduced in versions 1.3.1 and 1.2.2.
    least_conn;

    server 127.0.0.1:8080;
    server 127.0.0.1:8081;
    ## Create a backend connection cache. Note that this requires
    ## Nginx version greater or equal to 1.1.4.
    ## Cf. http://nginx.org/en/CHANGES. Comment out the following
    ## line if that's not the case.
    keepalive 5;
}

## Add a third pool as a fallback. Note that this requires php-cgi
## side by side php-fpm. If you don't have it installed comment it
## out.
upstream phpapache_backup {
    server 127.0.0.1:8082;
    ## Create a backend connection cache. Note that this requires
    ## Nginx version greater or equal to 1.1.4.
    ## Cf. http://nginx.org/en/CHANGES. Comment out the
