With the release of RadControls for ASP.NET Ajax Q3 2009 SP1 we introduced built-in CDN support. It was very logical that Telerik Extensions for ASP.NET MVC receive some CDN love as well. Now this is a fact! Go download the current release from here (open source) or here (licensed).


Enabling global CDN support from web.config

Add the following XML in your web.config:

<sectionGroup name="telerik">
<section name="webAssets" type="Telerik.Web.Mvc.Configuration.WebAssetConfigurationSection, Telerik.Web.Mvc"/>
<webAssets useTelerikContentDeliveryNetwork="true" />

Enable CDN support from code

.DefaultGroup(group => group.UseTelerikContentDeliveryNetwork(true))


Questions and Answers

  1. Which files are served from the Telerik CDN?
    Only telerik “native files” get served from the CDN – JavaScript, CSS and images.
  2. Where is Telerik CDN hosted?
    Amazon CloudFront
  3. What is the URL that will be output?
    • JavaScript: http://aspnet-scripts.telerikstatic.com/mvc|mvcz/assemblyVersion (mvc or mvcz depends whether the browser supports GZIP content encoding)
    • CSS and image files: http://aspnet-skins.telerikstatic.com/mvc|mvcz/assemblyVersion (mvc or mvcz depends whether the browser supports GZIP content encoding)
  4. What about SSL support?
    SSL is automatically detected and then the following will be output:
    • CSS and image files: https://telerik-aspnet-skins.s3.amazonaws.com/mvc|mvcz/assemblyVersion
    • JavaScript files: https://telerik-aspnet-scripts.s3.amazonaws.com/mvc|mvcz/assemblyVersion

Is there anything else in this release

Actually yes. We have implemented RTL support for the tabstrip, panelbar and menu.
