Dynamic CDN for front-end assets.

Description
-----------

[](#description)

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 ().

Installation
------------

[](#installation)

### Manual Installation

[](#manual-installation)

1. Upload the entire `/dynamic-cdn` directory to the `/wp-content/plugins/` directory.
2. Activate Dynamic CDN through the 'Plugins' menu in WordPress.

Frequently Asked Questions
--------------------------

[](#frequently-asked-questions)

### Will this work as a mu-plugin?

[](#will-this-work-as-a-mu-plugin)

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.

### How do I add a domain?

[](#how-do-i-add-a-domain)

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' );

```

### What if I want to add my domains through wp-config.php?

[](#what-if-i-want-to-add-my-domains-through-wp-configphp)

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' );

```

### What if I don't add any domains, will this break my images?

[](#what-if-i-dont-add-any-domains-will-this-break-my-images)

Hopefully not. If you haven't added any domains the plugin will not rewrite anything, bypassing your images entirely.

Screenshots

None at this time.

Upgrade Notice
--------------

[](#upgrade-notice)

### 0.4.0

[](#040-1)

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.
