Announcing the Microsoft AJAX CDN – ScottGu’s Blog

Earlier today the ASP.NET team launched a new 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.

this makes it ultra-easy to have ASP.NET AJAX libraries served automatically to your website’s users from the fastest (closes) possible server.
