<p>We need to determine the subdomain pattern (ex: http://cdn-#.domain.tld ) substitution and the maximum number of subdomains we want to work with (ex: 5).</p>
<p>The pattern will transform an url like this ‘http://www.domain.tld/img/source1.jpg’ to this new url structure ‘http://cdn-X.domain.tld/img/source1.jpg’ where X ranges from 1 to 5 (max).</p>
<p>NOTE: If you have trouble accessing images using the new address because WordPress asks you to register the domain then you must insert the following line in the file wp-config.php</p>
<pre><code>include_once(ABSPATH.'wp-content/plugins/domain-sharding/domain-sharding-alias.php'); 
</code></pre>
<p>Then you need to be sure to set write permissions to the aliases folder located within the plugin directory.</p>
<p>NOTE: You’ll need to manually create the new A records for the subdomains in your DNS panel. They should have the same ip address of your main domain.</p>
