+Proxy template allow you to use Nginx as reverse proxy. Usefull when you have application serveur such as Redmine, Jenkins...

+
+Note: Few params are unavailable on old Nginx version. But this role don't put it if your version is too old!
+
+#### Upstream params
+
+- `name`: upstream name. Can be use in vhost with *proxy_pass http://upstream_name*
+- `params`: list of param (hash, zone...)
+- `servers`: each upstream MUST have at least 1 server
+
+#### Server params
+
+You must set a `path`. For example: *192.168.0.50:8080* or *unix:/tmp/my.sock*.
+
+All this params are optional. You should see [Nginx upstream doc](http://nginx.org/en/docs/http/ngx_http_upstream_module.html).
