Adjusting IIS Settings for Websites
You or site owners can customize IIS configuration for a particular website in the Customer Panel in Websites & Domains > select a domain > IIS Settings. All the settings are divided into three groups:
The section Common settings contains the settings that website owners typically want to adjust. For example, to add custom index files or allow directory browsing. For each parameter, you can either type a custom value, or use the default IIS configuration (by selecting the Default value).
Directory Security Settings
The settings in the section Directory security settings allow you to enforce HTTPS connections and to prohibit anonymous access to the site.
Access Restriction Settings
The settings in the section Access restriction settings allow you to control access to the website by IP addresses.Note: As opposed to other web server settings, the Deny access to the site parameter does not override but supplements the list of IP addresses provided in the default configuration. In case of a conflict (for example, when you allow the address that is denied in the default configuration), your values will be used.
