Microsoft has launched the
AJAX CDN (content delivery network) service for caching AJAX and ASP.Net jQuery libraries. According
to the developers themselves, using this cache can significantly improve the performance of ASP.Net Web Forms and ASP.Net MVC web applications.
Ajax CDN works according to the standard CDN principle, that is, the content is duplicated on multiple servers geographically remote from each other, and each user is served by the server closest to him. To request a CDN, simply change the address of the script in the code of the web page:

')
Many standard scripts are already on the CDN (the list is
here ), in the future they promise to replenish the catalog considerably.
In addition to speeding up the load on the user’s side, using this service you can tritely save on traffic, since Ajax CDN is free for both private and commercial use, and does not require registration.
Talking about Microsoft Ajax tools, the company recently updated the
ASP.Net AJAX Preview 5 set of client-server JavaScript libraries to create Ajax applications. New features include dynamic and recursive patterns, binding converters and compatibility with ASP.Net UpdatePanel.
We also add that Microsoft recently introduced the
MS Doloto tool for optimizing Ajax applications.
