CMS CDN

This module allows for multiple site owners to utilize a single shared domain and CDN for all core JavaScript and CSS files. By serving these shared files from a single domain your end users will gain significant caching as they go from one Drupal site to another.

As an example, rather than serving the /misc/jquery.js file from your local server, or even a private CDN domain after installing this module you're file will be served from:
http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js

Other core files, that are specific to Drupal will be available based on your version of Drupal which is determined by the module. For example the /misc/drupal.js file will now be served here if you were using version 6.17:
http://j.cmscdn.net/drupal/6.17/misc/drupal.js

This module is meant for moderate traffic sites, with no more than 1,000 pageviews per day. If you would like to use the module on higher traffic sites please contact the module maintainer.

This module is not a replacement for the http://drupal.org/project/cdn module, however can work along side that one if you feel it is necessary.

Tag Sell It is a site the module maintainer runs, and is actively using the module.
