Microsoft has launched Microsoft Ajax CDN (Content Delivery Network) service that provides caching support for AJAX libraries (including jQuery and ASP.NET AJAX). The service is available for free, does not require any registration, and can be used for both commercial and non-commercial purposes.
CDN enables you to easily add Microsoft Ajax Library and jQuery scripts to your Web applications. You can start using the Microsoft Ajax Library or jQuery simply by adding a <script> tag to your page that points to Ajax.Microsoft.com.
For more information on how to use CDN and how it can help you in your Web development, see Microsoft Ajax CDN. For a list of what is cached, see Microsoft Ajax Releases on the CDN and jQuery Releases on the CDN. For an overview, see Scott Gurthrie’s blog post, Announcing the Microsoft AJAX CDN.
