-`filename`: (O) Specify filename in /etc/nginx/sites-*. Do NOT specify default (reserved keyword). It will be used for log filenames and directories creation.
-`headers`: (O) Set additionals header as key/value list. You can append "always" to the value. Show [nginx doc](http://nginx.org/en/docs/http/ngx_http_headers_module.html).
-`location_order`: (O) Due to non preditive `location` order, you can provide the good order (see test-location.local in [tests/test.yml](../tests/test.yml)).
-`upstream_params`: (O) Add upstream params (useful when you want to pass variables to PHP)
-`override_try_files`: (O) overrides default try\_files defined in template
-`manage_local_content`: (O) Boolean. Set to false if you do not want to manage local content (images, css...). This option is useless if you use `_proxy` template or `redirect_to` feature.
-`proto`: (O) list of protocol used. Default is a list with "http". If you need http and https, you must set a list with "http" and "https". You can only set "https" without http support.
