Hosted Libraries - Developer's Guide - Make the Web Faster. Cdnjs - the missing cdn. JsDelivr - Free CDN for javascript libraries, jQuery plugins, CSS frameworks, Fonts and more. Microsoft Ajax Content Delivery Network - ASP.NET Ajax Library. The Microsoft Ajax Content Delivery Network (CDN) hosts popular third party JavaScript libraries such as jQuery and enables you to easily add them to your Web applications.
For example, you can start using jQuery which is hosted on this CDN simply by adding a <script> tag to your page that points to ajax.aspnetcdn.com. By taking advantage of the CDN, you can significantly improve the performance of your Ajax applications. The contents of the CDN are cached on servers located around the world. In addition, the CDN enables browsers to reuse cached third party JavaScript files for web sites that are located in different domains. The CDN supports SSL (HTTPS) in case you need to serve a web page using the Secure Sockets Layer.
