Top level configuration

The Lua config have to specify 4 variables:

domain_name: Your domain name such as "example.xyz"
key_path: The path to your SSL keys such as "/etc/letsencrypt/live/" if you are using certbot.
hosts: A table whose keys are the host names and whose values are a table with the host's configuration.
extra: An optional string that will be added as-is on the output file.

Host configuration

The configuration for each host is a table, this table must have the fields http, https, and target.

The field http can have the following value:

"no": In that case, the server does not serves HTTP on this host.
"server": The host will act as a web server. The path to the files to serve are in the target field.
"proxy": The host will act as a proxy. The target URL must be in the target field.
"redirection": The host will redirect to the URL in the target field.

The field https can have the same values or the "auto" value which make so that the HTTPS host acts as a proxy for the HTTP host.

By default, the HTTP and HTTPS hosts will have the same targets. But you can specify a different target for the HTTPS host in the field target_https.
