You can customize Apache configuration for a particular website in the
Customer Panel on the Websites & Domains > <domain_name> > Apache
& nginx Settings page.
Adjusting Common Apache Settings
The section Common Apache settings contains the settings that
website owners typically want to adjust. For example, to add custom
index files or restrict access to the site by IP address. For each
parameter, you can either type a custom value, or use the default Apache
configuration (by selecting the Default value).
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.
Adjusting Additional Apache Directives
To add Apache directives for a website that are not available in the
Common Apache settings, use the Additional directives for HTTP
and Additional directives for HTTPS fields. When editing the fields,
use the syntax as in httpd.conf. For example, if you want to set a
custom error page, add the line:
ErrorDocument 401 /my_error_page.html
Note: Your customers cannot view and edit these fields.
Note: When a website has “Permanent SEO-safe 301 redirect from HTTP to
HTTPS” enabled, only additional directives for HTTPS
are applied, while additional directives for HTTP are not.
