## Description

For busy websites, using a CDN (Content Delivery Network) to transfer static content
such as images, javascripts, stylesheets, Flash etc. is highly recommended (as listed
in Yahoo!’s [Best Practices for Speeding Up Your Web Site](http://developer.yahoo.com/performance/rules.html))
as it reduces server load and bandwidth thus improves stability and availability.

There is a catch – Commerical CDN’s like Akamai and Limelight are not cheap at all.
Good news, we have an exception however – the free, P2P-based [CoralCDN](http://www.coralcdn.org/)
allows us to take full advantage of a powereful CDN without spending a dime. How
to use it? Well, basically, just append `.nyud.net` to the hostname of any URL, 
and that URL will be handled by Coral – simple.

This plugin takes that simplicity one step further (or closer?) by rewriting your
static files’ URL’s (JavaScripts, CSS, images etc.) so that they are served from
Coral servers instead of your own. You don’t have to touch anything! Just enable
it, and boom! your static contents are handled with care by Coral’s powerful server
clusters.

If you are paying bandwidth fee, this plugin hopefully helps with your bills. Even
if you don’t, enabling it may save your site in peak times.

### Features

 * Just enable the plugin and call it done – no extra steps required!
 * You can exclusively select the content types to be served through CoralCDN – 
   currently supporting JS, CSS, images, inline background images, and <object>’
   s
 * Additional URL’s can be added as includes or excludes
 * Debug mode gives you a good preview to make sure nothing goes wrong
 * Works normally with other plugins. Especially useful if run along with WP Super
   Cache
 * AJAX’ed admin section makes it quick and easy to adjust the settings

## FAQ

  I just enabled Free CDN. Now my contents take longer than usual to be downloaded!

The speed of downloading static contents is 100% decided by Coral servers. Depending
on the server status, sometimes it may take a bit longer for the contents to be 
downloaded. If the performance is not satisfied, you may want to enable the plugin
in certain peak times only.

  My JavaScripts got broken! My cookies just don’t work! [Insert error here]

If your javascript doesn’t work anymore, best bet is to uncheck “External JavaScript
includes” from “Using CDN on these contents” option section. You can also enable
Debug mode to see which files get involved, and try excluding them one by one to
find out the problematic one and deal with it for good.

  Why doesn’t the plugin parse the external stylesheet and rewrite the background
images there too?

There should be no need. If the stylesheet got rewritten and is served through Coral,
all relative (most commonly) background images defined inside it will be pulled 
from Coral servers too.

  Everything went wrong! My site is now totally blank/ messed up!

Looks like a plugin conflict. Try disabling your plugins one by one to find out 
which caused the problem.
