Restrict Access to Addon Domains through the Main Domain

Summary

All Addon Domains must be associated with a subdomain. You are able to disable access to the subdomain, this article will show you how to do this.

Disable access to a subdomain

The following is an example '.htaccess' code which provides a thorough means of making the Addon domain folders, and their contents, invisible through the main domain by forcing a "404 Not Found" error. This will work both for web browsers and search engines:

    RewriteEngine On
            RewriteCond %{HTTP_HOST} ^(www.)?domain.com$ [NC]
            RewriteCond %{REQUEST_URI} ^/addonfolder/(.*)$
            RewriteRule ^(.*)$ - [L,R=404]
The example rewrite rules will force 'http://www.domain.com/addonfolder/' and any of its contents to report the "404 Not Found" error.

Be sure to replace the 'domain.com' in the example with your hosting account's main domain address and 'addonfolder' with the name of the folder for your Addon domain.

This can also be applied to multiple Addon domain folders through the use of the [OR] option as in the following example in which 3 Addon folders are being reported as "404 Not Found" when accessed through the main domain:

    RewriteEngine On
            RewriteCond %{HTTP_HOST} ^(www.)?domain.com$ [NC]
            RewriteCond %{REQUEST_URI} ^/addon1/(.*)$ [OR]
            RewriteCond %{REQUEST_URI} ^/addon2/(.*)$ [OR]
            RewriteCond %{REQUEST_URI} ^/addon3/(.*)$
            RewriteRule ^(.*)$ - [L,R=404]
