This plugin allows you to easily dequeue styles and scripts from your site’s queue.
It also allows you to check which ones are called from the Archive, Single, Page and Frontpage templates of your site.
Once you used it, you can copy&paste generated code to your plugin or theme files.
This plugin can break your site frontend, so be careful when using it. If you don’t know what you are doing, please don’t use this plugin.

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).
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).
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
<pre><code>include_once(ABSPATH.'wp-content/plugins/domain-sharding/domain-sharding-alias.php'); 
</code></pre>
Then you need to be sure to set write permissions to the aliases folder located within the plugin directory.
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.
