There is a single form that lists all of the settings for your proxy server. The proxy server's technical settings come from the magnus.conf file, and the content settings come from obj.conf. You first specified this directory during installation. Hostname is the URL clients will use to access your server. Port is the port on your system that the server listens to for HTTP requests.
Error log is the name and path of the server's error log file.
User is the user the server runs as. Processes is the number of processes your server uses when it starts. DNS shows whether DNS is enabled or disabled. The server's content settings depend on how you've configured your server. Typically, the proxy lists all templates, URL mappings, and access control.
