Dynamic CDN for front-end assets.
Dynamic solution for rewriting image asset URLs to a hosted content delivery network (CDN) with optional domain sharding for concurrent downloads.
This plugin is based heavily on the CDN dropin from Mark Jaquith's WP_Stack (https://github.com/markjaquith/WP-Stack).
- Upload the entire
/dynamic-cdndirectory to the/wp-content/plugins/directory. - Activate Dynamic CDN through the 'Plugins' menu in WordPress.
Yes. The plugin, as designed, will work just fine in the mu-plugins directory. We highly recommend a second mu-plugin be added to configure the CDN domains used by the system.
In a function wired to dynamic_cdn_first_loaded, you'll reference the ->add_domain() method of the Dynamic_CDN object. For example:
function my_cdn_domains() {
$manager = DomainManager::last();
$manager->add( 'cdn0.mydomain.com' );
$manager->add( 'cdn1.mydomain.com' );
$manager->add( 'cdn2.mydomain.com' );
}
add_action( 'dynamic_cdn_first_loaded', 'my_cdn_domains' );
Simply define a DYNCDN_DOMAINS constant that's a comma-delimited list of your cdn domains. For example:
define( 'DYNCDN_DOMAINS', 'cdn0.mydomain.com,cdn1.mydomain.com,cdn2.mydomain.com' );
Hopefully not. If you haven't added any domains the plugin will not rewrite anything, bypassing your images entirely.
None at this time.

- First release
Domain management has moved from a general-purpose class to a purpose-built DomainManager object. This object is
instantiated with your current site's domain name, and can be accessed throught the static DomainManager::last() helper.
(This method automatically returns the last-instantiated domain manager). If you weren't manipulating CdN domains
programmatically, you won't need to change anything at all.
