Scott Guthrie announced the launch of the Microsoft Ajax CDN on his blog last night. If you have not read his post, I recommend that you read it now to get a general overview of the CDN and how you can take advantage of the CDN to improve the performance of your ASP.NET Web Forms and ASP.NET MVC applications:
“The Microsoft Ajax CDN enables you to significantly improve the performance of ASP.NET Web Forms and ASP.NET MVC applications that use ASP.NET AJAX or jQuery. The service is available for free, does not require any registration, and can be used for both commercial and non-commercial purposes.
If you are not familiar with the jQuery Validation library then you should know that this is one of the most popular form validation libraries used by jQuery developers. Microsoft is shipping the jQuery validation library with both ASP.NET Web Forms and ASP.NET MVC in Visual Studio 2010. Furthermore, jQuery Validation library will be integrated with ASP.NET MVC.
